DESCRIPTION

26       You can query/set/replace/unset options with this command. The name is
27       actually the section and the key separated by a dot, and the value will
28       be escaped.
29
30       Multiple lines can be added to an option by using the --add option. If
31       you want to update or unset an option which can occur on multiple
32       lines, a value-pattern (which is an extended regular expression, unless
33       the --fixed-value option is given) needs to be given. Only the existing
34       values that match the pattern are updated or unset. If you want to
35       handle the lines that do not match the pattern, just prepend a single
36       exclamation mark in front (see also the section called “EXAMPLES”), but
37       note that this only works when the --fixed-value option is not in use.
38
39       The --type=<type> option instructs git config to ensure that incoming
40       and outgoing values are canonicalize-able under the given <type>. If no
41       --type=<type> is given, no canonicalization will be performed. Callers
42       may unset an existing --type specifier with --no-type.
43
44       When reading, the values are read from the system, global and
45       repository local configuration files by default, and options --system,
46       --global, --local, --worktree and --file <filename> can be used to tell
47       the command to read from only that location (see the section called
48       “FILES”).
49
50       When writing, the new value is written to the repository local
51       configuration file by default, and options --system, --global,
52       --worktree, --file <filename> can be used to tell the command to write
53       to that location (you can say --local but that is the default).
54
55       This command will fail with non-zero status upon error. Some exit codes
56       are:
57
58       •   The section or key is invalid (ret=1),
59
60       •   no section or name was provided (ret=2),
61
62       •   the config file is invalid (ret=3),
63
64       •   the config file cannot be written (ret=4),
65
66       •   you try to unset an option which does not exist (ret=5),
67
68       •   you try to unset/set an option for which multiple lines match
69           (ret=5), or
70
71       •   you try to use an invalid regexp (ret=6).
72
73       On success, the command returns the exit code 0.
74
75       A list of all available configuration variables can be obtained using
76       the git help --config command.
77

OPTIONS

79       --replace-all
80           Default behavior is to replace at most one line. This replaces all
81           lines matching the key (and optionally the value-pattern).
82
83       --add
84           Adds a new line to the option without altering any existing values.
85           This is the same as providing ^$ as the value-pattern in
86           --replace-all.
87
88       --get
89           Get the value for a given key (optionally filtered by a regex
90           matching the value). Returns error code 1 if the key was not found
91           and the last value if multiple key values were found.
92
93       --get-all
94           Like get, but returns all values for a multi-valued key.
95
96       --get-regexp
97           Like --get-all, but interprets the name as a regular expression and
98           writes out the key names. Regular expression matching is currently
99           case-sensitive and done against a canonicalized version of the key
100           in which section and variable names are lowercased, but subsection
101           names are not.
102
103       --get-urlmatch <name> <URL>
104           When given a two-part name section.key, the value for
105           section.<URL>.key whose <URL> part matches the best to the given
106           URL is returned (if no such key exists, the value for section.key
107           is used as a fallback). When given just the section as name, do so
108           for all the keys in the section and list them. Returns error code 1
109           if no value is found.
110
111       --global
112           For writing options: write to global ~/.gitconfig file rather than
113           the repository .git/config, write to $XDG_CONFIG_HOME/git/config
114           file if this file exists and the ~/.gitconfig file doesn’t.
115
116           For reading options: read only from global ~/.gitconfig and from
117           $XDG_CONFIG_HOME/git/config rather than from all available files.
118
119           See also the section called “FILES”.
120
121       --system
122           For writing options: write to system-wide $(prefix)/etc/gitconfig
123           rather than the repository .git/config.
124
125           For reading options: read only from system-wide
126           $(prefix)/etc/gitconfig rather than from all available files.
127
128           See also the section called “FILES”.
129
130       --local
131           For writing options: write to the repository .git/config file. This
132           is the default behavior.
133
134           For reading options: read only from the repository .git/config
135           rather than from all available files.
136
137           See also the section called “FILES”.
138
139       --worktree
140           Similar to --local except that $GIT_DIR/config.worktree is read
141           from or written to if extensions.worktreeConfig is enabled. If not
142           it’s the same as --local. Note that $GIT_DIR is equal to
143           $GIT_COMMON_DIR for the main working tree, but is of the form
144           $GIT_DIR/worktrees/<id>/ for other working trees. See git-
145           worktree(1) to learn how to enable extensions.worktreeConfig.
146
147       -f <config-file>, --file <config-file>
148           For writing options: write to the specified file rather than the
149           repository .git/config.
150
151           For reading options: read only from the specified file rather than
152           from all available files.
153
154           See also the section called “FILES”.
155
156       --blob <blob>
157           Similar to --file but use the given blob instead of a file. E.g.
158           you can use master:.gitmodules to read values from the file
159           .gitmodules in the master branch. See "SPECIFYING REVISIONS"
160           section in gitrevisions(7) for a more complete list of ways to
161           spell blob names.
162
163       --remove-section
164           Remove the given section from the configuration file.
165
166       --rename-section
167           Rename the given section to a new name.
168
169       --unset
170           Remove the line matching the key from config file.
171
172       --unset-all
173           Remove all lines matching the key from config file.
174
175       -l, --list
176           List all variables set in config file, along with their values.
177
178       --fixed-value
179           When used with the value-pattern argument, treat value-pattern as
180           an exact string instead of a regular expression. This will restrict
181           the name/value pairs that are matched to only those where the value
182           is exactly equal to the value-pattern.
183
184       --type <type>
185           git config will ensure that any input or output is valid under the
186           given type constraint(s), and will canonicalize outgoing values in
187           <type>'s canonical form.
188
189           Valid <type>'s include:
190
191bool: canonicalize values as either "true" or "false".
192
193int: canonicalize values as simple decimal numbers. An optional
194               suffix of k, m, or g will cause the value to be multiplied by
195               1024, 1048576, or 1073741824 upon input.
196
197bool-or-int: canonicalize according to either bool or int, as
198               described above.
199
200path: canonicalize by expanding a leading ~ to the value of
201               $HOME and ~user to the home directory for the specified user.
202               This specifier has no effect when setting the value (but you
203               can use git config section.variable ~/ from the command line to
204               let your shell do the expansion.)
205
206expiry-date: canonicalize by converting from a fixed or
207               relative date-string to a timestamp. This specifier has no
208               effect when setting the value.
209
210color: When getting a value, canonicalize by converting to an
211               ANSI color escape sequence. When setting a value, a
212               sanity-check is performed to ensure that the given value is
213               canonicalize-able as an ANSI color, but it is written as-is.
214
215       --bool, --int, --bool-or-int, --path, --expiry-date
216           Historical options for selecting a type specifier. Prefer instead
217           --type (see above).
218
219       --no-type
220           Un-sets the previously set type specifier (if one was previously
221           set). This option requests that git config not canonicalize the
222           retrieved variable.  --no-type has no effect without --type=<type>
223           or --<type>.
224
225       -z, --null
226           For all options that output values and/or keys, always end values
227           with the null character (instead of a newline). Use newline instead
228           as a delimiter between key and value. This allows for secure
229           parsing of the output without getting confused e.g. by values that
230           contain line breaks.
231
232       --name-only
233           Output only the names of config variables for --list or
234           --get-regexp.
235
236       --show-origin
237           Augment the output of all queried config options with the origin
238           type (file, standard input, blob, command line) and the actual
239           origin (config file path, ref, or blob id if applicable).
240
241       --show-scope
242           Similar to --show-origin in that it augments the output of all
243           queried config options with the scope of that value (worktree,
244           local, global, system, command).
245
246       --get-colorbool <name> [<stdout-is-tty>]
247           Find the color setting for <name> (e.g.  color.diff) and output
248           "true" or "false".  <stdout-is-tty> should be either "true" or
249           "false", and is taken into account when configuration says "auto".
250           If <stdout-is-tty> is missing, then checks the standard output of
251           the command itself, and exits with status 0 if color is to be used,
252           or exits with status 1 otherwise. When the color setting for name
253           is undefined, the command uses color.ui as fallback.
254
255       --get-color <name> [<default>]
256           Find the color configured for name (e.g.  color.diff.new) and
257           output it as the ANSI color escape sequence to the standard output.
258           The optional default parameter is used instead, if there is no
259           color configured for name.
260
261           --type=color [--default=<default>] is preferred over --get-color
262           (but note that --get-color will omit the trailing newline printed
263           by --type=color).
264
265       -e, --edit
266           Opens an editor to modify the specified config file; either
267           --system, --global, or repository (default).
268
269       --[no-]includes
270           Respect include.*  directives in config files when looking up
271           values. Defaults to off when a specific file is given (e.g., using
272           --file, --global, etc) and on when searching all config files.
273
274       --default <value>
275           When using --get, and the requested variable is not found, behave
276           as if <value> were the value assigned to the that variable.
277

CONFIGURATION

279       pager.config is only respected when listing configuration, i.e., when
280       using --list or any of the --get-* which may return multiple results.
281       The default is to use a pager.
282

FILES

284       By default, git config will read configuration options from multiple
285       files:
286
287       $(prefix)/etc/gitconfig
288           System-wide configuration file.
289
290       $XDG_CONFIG_HOME/git/config, ~/.gitconfig
291           User-specific configuration files. When the XDG_CONFIG_HOME
292           environment variable is not set or empty, $HOME/.config/ is used as
293           $XDG_CONFIG_HOME.
294
295           These are also called "global" configuration files. If both files
296           exist, both files are read in the order given above.
297
298       $GIT_DIR/config
299           Repository specific configuration file.
300
301       $GIT_DIR/config.worktree
302           This is optional and is only searched when
303           extensions.worktreeConfig is present in $GIT_DIR/config.
304
305       You may also provide additional configuration parameters when running
306       any git command by using the -c option. See git(1) for details.
307
308       Options will be read from all of these files that are available. If the
309       global or the system-wide configuration files are missing or unreadable
310       they will be ignored. If the repository configuration file is missing
311       or unreadable, git config will exit with a non-zero error code. An
312       error message is produced if the file is unreadable, but not if it is
313       missing.
314
315       The files are read in the order given above, with last value found
316       taking precedence over values read earlier. When multiple values are
317       taken then all values of a key from all files will be used.
318
319       By default, options are only written to the repository specific
320       configuration file. Note that this also affects options like
321       --replace-all and --unset. git config will only ever change one file at
322       a time.
323
324       You can limit which configuration sources are read from or written to
325       by specifying the path of a file with the --file option, or by
326       specifying a configuration scope with --system, --global, --local, or
327       --worktree. For more, see the section called “OPTIONS” above.
328

SCOPES

330       Each configuration source falls within a configuration scope. The
331       scopes are:
332
333       system
334           $(prefix)/etc/gitconfig
335
336       global
337           $XDG_CONFIG_HOME/git/config
338
339           ~/.gitconfig
340
341       local
342           $GIT_DIR/config
343
344       worktree
345           $GIT_DIR/config.worktree
346
347       command
348           GIT_CONFIG_{COUNT,KEY,VALUE} environment variables (see the section
349           called “ENVIRONMENT” below)
350
351           the -c option
352
353       With the exception of command, each scope corresponds to a command line
354       option: --system, --global, --local, --worktree.
355
356       When reading options, specifying a scope will only read options from
357       the files within that scope. When writing options, specifying a scope
358       will write to the files within that scope (instead of the repository
359       specific configuration file). See the section called “OPTIONS” above
360       for a complete description.
361
362       Most configuration options are respected regardless of the scope it is
363       defined in, but some options are only respected in certain scopes. See
364       the respective option’s documentation for the full details.
365
366   Protected configuration
367       Protected configuration refers to the system, global, and command
368       scopes. For security reasons, certain options are only respected when
369       they are specified in protected configuration, and ignored otherwise.
370
371       Git treats these scopes as if they are controlled by the user or a
372       trusted administrator. This is because an attacker who controls these
373       scopes can do substantial harm without using Git, so it is assumed that
374       the user’s environment protects these scopes against attackers.
375

ENVIRONMENT

377       GIT_CONFIG_GLOBAL, GIT_CONFIG_SYSTEM
378           Take the configuration from the given files instead from global or
379           system-level configuration. See git(1) for details.
380
381       GIT_CONFIG_NOSYSTEM
382           Whether to skip reading settings from the system-wide
383           $(prefix)/etc/gitconfig file. See git(1) for details.
384
385       See also the section called “FILES”.
386
387       GIT_CONFIG_COUNT, GIT_CONFIG_KEY_<n>, GIT_CONFIG_VALUE_<n>
388           If GIT_CONFIG_COUNT is set to a positive number, all environment
389           pairs GIT_CONFIG_KEY_<n> and GIT_CONFIG_VALUE_<n> up to that number
390           will be added to the process’s runtime configuration. The config
391           pairs are zero-indexed. Any missing key or value is treated as an
392           error. An empty GIT_CONFIG_COUNT is treated the same as
393           GIT_CONFIG_COUNT=0, namely no pairs are processed. These
394           environment variables will override values in configuration files,
395           but will be overridden by any explicit options passed via git -c.
396
397           This is useful for cases where you want to spawn multiple git
398           commands with a common configuration but cannot depend on a
399           configuration file, for example when writing scripts.
400
401       GIT_CONFIG
402           If no --file option is provided to git config, use the file given
403           by GIT_CONFIG as if it were provided via --file. This variable has
404           no effect on other Git commands, and is mostly for historical
405           compatibility; there is generally no reason to use it instead of
406           the --file option.
407

EXAMPLES

409       Given a .git/config like this:
410
411           #
412           # This is the config file, and
413           # a '#' or ';' character indicates
414           # a comment
415           #
416
417           ; core variables
418           [core]
419                   ; Don't trust file modes
420                   filemode = false
421
422           ; Our diff algorithm
423           [diff]
424                   external = /usr/local/bin/diff-wrapper
425                   renames = true
426
427           ; Proxy settings
428           [core]
429                   gitproxy=proxy-command for kernel.org
430                   gitproxy=default-proxy ; for all the rest
431
432           ; HTTP
433           [http]
434                   sslVerify
435           [http "https://weak.example.com"]
436                   sslVerify = false
437                   cookieFile = /tmp/cookie.txt
438
439       you can set the filemode to true with
440
441           % git config core.filemode true
442
443       The hypothetical proxy command entries actually have a postfix to
444       discern what URL they apply to. Here is how to change the entry for
445       kernel.org to "ssh".
446
447           % git config core.gitproxy '"ssh" for kernel.org' 'for kernel.org$'
448
449       This makes sure that only the key/value pair for kernel.org is
450       replaced.
451
452       To delete the entry for renames, do
453
454           % git config --unset diff.renames
455
456       If you want to delete an entry for a multivar (like core.gitproxy
457       above), you have to provide a regex matching the value of exactly one
458       line.
459
460       To query the value for a given key, do
461
462           % git config --get core.filemode
463
464       or
465
466           % git config core.filemode
467
468       or, to query a multivar:
469
470           % git config --get core.gitproxy "for kernel.org$"
471
472       If you want to know all the values for a multivar, do:
473
474           % git config --get-all core.gitproxy
475
476       If you like to live dangerously, you can replace all core.gitproxy by a
477       new one with
478
479           % git config --replace-all core.gitproxy ssh
480
481       However, if you really only want to replace the line for the default
482       proxy, i.e. the one without a "for ..." postfix, do something like
483       this:
484
485           % git config core.gitproxy ssh '! for '
486
487       To actually match only values with an exclamation mark, you have to
488
489           % git config section.key value '[!]'
490
491       To add a new proxy, without altering any of the existing ones, use
492
493           % git config --add core.gitproxy '"proxy-command" for example.com'
494
495       An example to use customized color from the configuration in your
496       script:
497
498           #!/bin/sh
499           WS=$(git config --get-color color.diff.whitespace "blue reverse")
500           RESET=$(git config --get-color "" "reset")
501           echo "${WS}your whitespace color or blue reverse${RESET}"
502
503       For URLs in https://weak.example.com, http.sslVerify is set to false,
504       while it is set to true for all others:
505
506           % git config --type=bool --get-urlmatch http.sslverify https://good.example.com
507           true
508           % git config --type=bool --get-urlmatch http.sslverify https://weak.example.com
509           false
510           % git config --get-urlmatch http https://weak.example.com
511           http.cookieFile /tmp/cookie.txt
512           http.sslverify false
513

CONFIGURATION FILE

515       The Git configuration file contains a number of variables that affect
516       the Git commands' behavior. The files .git/config and optionally
517       config.worktree (see the "CONFIGURATION FILE" section of git-
518       worktree(1)) in each repository are used to store the configuration for
519       that repository, and $HOME/.gitconfig is used to store a per-user
520       configuration as fallback values for the .git/config file. The file
521       /etc/gitconfig can be used to store a system-wide default
522       configuration.
523
524       The configuration variables are used by both the Git plumbing and the
525       porcelain commands. The variables are divided into sections, wherein
526       the fully qualified variable name of the variable itself is the last
527       dot-separated segment and the section name is everything before the
528       last dot. The variable names are case-insensitive, allow only
529       alphanumeric characters and -, and must start with an alphabetic
530       character. Some variables may appear multiple times; we say then that
531       the variable is multivalued.
532
533   Syntax
534       The syntax is fairly flexible and permissive; whitespaces are mostly
535       ignored. The # and ; characters begin comments to the end of line,
536       blank lines are ignored.
537
538       The file consists of sections and variables. A section begins with the
539       name of the section in square brackets and continues until the next
540       section begins. Section names are case-insensitive. Only alphanumeric
541       characters, - and . are allowed in section names. Each variable must
542       belong to some section, which means that there must be a section header
543       before the first setting of a variable.
544
545       Sections can be further divided into subsections. To begin a subsection
546       put its name in double quotes, separated by space from the section
547       name, in the section header, like in the example below:
548
549                   [section "subsection"]
550
551       Subsection names are case sensitive and can contain any characters
552       except newline and the null byte. Doublequote " and backslash can be
553       included by escaping them as \" and \\, respectively. Backslashes
554       preceding other characters are dropped when reading; for example, \t is
555       read as t and \0 is read as 0. Section headers cannot span multiple
556       lines. Variables may belong directly to a section or to a given
557       subsection. You can have [section] if you have [section "subsection"],
558       but you don’t need to.
559
560       There is also a deprecated [section.subsection] syntax. With this
561       syntax, the subsection name is converted to lower-case and is also
562       compared case sensitively. These subsection names follow the same
563       restrictions as section names.
564
565       All the other lines (and the remainder of the line after the section
566       header) are recognized as setting variables, in the form name = value
567       (or just name, which is a short-hand to say that the variable is the
568       boolean "true"). The variable names are case-insensitive, allow only
569       alphanumeric characters and -, and must start with an alphabetic
570       character.
571
572       A line that defines a value can be continued to the next line by ending
573       it with a \; the backslash and the end-of-line are stripped. Leading
574       whitespaces after name =, the remainder of the line after the first
575       comment character # or ;, and trailing whitespaces of the line are
576       discarded unless they are enclosed in double quotes. Internal
577       whitespaces within the value are retained verbatim.
578
579       Inside double quotes, double quote " and backslash \ characters must be
580       escaped: use \" for " and \\ for \.
581
582       The following escape sequences (beside \" and \\) are recognized: \n
583       for newline character (NL), \t for horizontal tabulation (HT, TAB) and
584       \b for backspace (BS). Other char escape sequences (including octal
585       escape sequences) are invalid.
586
587   Includes
588       The include and includeIf sections allow you to include config
589       directives from another source. These sections behave identically to
590       each other with the exception that includeIf sections may be ignored if
591       their condition does not evaluate to true; see "Conditional includes"
592       below.
593
594       You can include a config file from another by setting the special
595       include.path (or includeIf.*.path) variable to the name of the file to
596       be included. The variable takes a pathname as its value, and is subject
597       to tilde expansion. These variables can be given multiple times.
598
599       The contents of the included file are inserted immediately, as if they
600       had been found at the location of the include directive. If the value
601       of the variable is a relative path, the path is considered to be
602       relative to the configuration file in which the include directive was
603       found. See below for examples.
604
605   Conditional includes
606       You can conditionally include a config file from another by setting an
607       includeIf.<condition>.path variable to the name of the file to be
608       included.
609
610       The condition starts with a keyword followed by a colon and some data
611       whose format and meaning depends on the keyword. Supported keywords
612       are:
613
614       gitdir
615           The data that follows the keyword gitdir: is used as a glob
616           pattern. If the location of the .git directory matches the pattern,
617           the include condition is met.
618
619           The .git location may be auto-discovered, or come from $GIT_DIR
620           environment variable. If the repository is auto-discovered via a
621           .git file (e.g. from submodules, or a linked worktree), the .git
622           location would be the final location where the .git directory is,
623           not where the .git file is.
624
625           The pattern can contain standard globbing wildcards and two
626           additional ones, **/ and /**, that can match multiple path
627           components. Please refer to gitignore(5) for details. For
628           convenience:
629
630           •   If the pattern starts with ~/, ~ will be substituted with the
631               content of the environment variable HOME.
632
633           •   If the pattern starts with ./, it is replaced with the
634               directory containing the current config file.
635
636           •   If the pattern does not start with either ~/, ./ or /, **/ will
637               be automatically prepended. For example, the pattern foo/bar
638               becomes **/foo/bar and would match /any/path/to/foo/bar.
639
640           •   If the pattern ends with /, ** will be automatically added. For
641               example, the pattern foo/ becomes foo/**. In other words, it
642               matches "foo" and everything inside, recursively.
643
644       gitdir/i
645           This is the same as gitdir except that matching is done
646           case-insensitively (e.g. on case-insensitive file systems)
647
648       onbranch
649           The data that follows the keyword onbranch: is taken to be a
650           pattern with standard globbing wildcards and two additional ones,
651           **/ and /**, that can match multiple path components. If we are in
652           a worktree where the name of the branch that is currently checked
653           out matches the pattern, the include condition is met.
654
655           If the pattern ends with /, ** will be automatically added. For
656           example, the pattern foo/ becomes foo/**. In other words, it
657           matches all branches that begin with foo/. This is useful if your
658           branches are organized hierarchically and you would like to apply a
659           configuration to all the branches in that hierarchy.
660
661       hasconfig:remote.*.url:
662           The data that follows this keyword is taken to be a pattern with
663           standard globbing wildcards and two additional ones, **/ and /**,
664           that can match multiple components. The first time this keyword is
665           seen, the rest of the config files will be scanned for remote URLs
666           (without applying any values). If there exists at least one remote
667           URL that matches this pattern, the include condition is met.
668
669           Files included by this option (directly or indirectly) are not
670           allowed to contain remote URLs.
671
672           Note that unlike other includeIf conditions, resolving this
673           condition relies on information that is not yet known at the point
674           of reading the condition. A typical use case is this option being
675           present as a system-level or global-level config, and the remote
676           URL being in a local-level config; hence the need to scan ahead
677           when resolving this condition. In order to avoid the
678           chicken-and-egg problem in which potentially-included files can
679           affect whether such files are potentially included, Git breaks the
680           cycle by prohibiting these files from affecting the resolution of
681           these conditions (thus, prohibiting them from declaring remote
682           URLs).
683
684           As for the naming of this keyword, it is for forwards compatibility
685           with a naming scheme that supports more variable-based include
686           conditions, but currently Git only supports the exact keyword
687           described above.
688
689       A few more notes on matching via gitdir and gitdir/i:
690
691       •   Symlinks in $GIT_DIR are not resolved before matching.
692
693       •   Both the symlink & realpath versions of paths will be matched
694           outside of $GIT_DIR. E.g. if ~/git is a symlink to
695           /mnt/storage/git, both gitdir:~/git and gitdir:/mnt/storage/git
696           will match.
697
698           This was not the case in the initial release of this feature in
699           v2.13.0, which only matched the realpath version. Configuration
700           that wants to be compatible with the initial release of this
701           feature needs to either specify only the realpath version, or both
702           versions.
703
704       •   Note that "../" is not special and will match literally, which is
705           unlikely what you want.

762
763   Values
764       Values of many variables are treated as a simple string, but there are
765       variables that take values of specific types and there are rules as to
766       how to spell them.
767
768       boolean
769           When a variable is said to take a boolean value, many synonyms are
770           accepted for true and false; these are all case-insensitive.
771
772           true
773               Boolean true literals are yes, on, true, and 1. Also, a
774               variable defined without = <value> is taken as true.
775
776           false
777               Boolean false literals are no, off, false, 0 and the empty
778               string.
779
780               When converting a value to its canonical form using the
781               --type=bool type specifier, git config will ensure that the
782               output is "true" or "false" (spelled in lowercase).
783
784       integer
785           The value for many variables that specify various sizes can be
786           suffixed with k, M,... to mean "scale the number by 1024", "by
787           1024x1024", etc.
788
789       color
790           The value for a variable that takes a color is a list of colors (at
791           most two, one for foreground and one for background) and attributes
792           (as many as you want), separated by spaces.
793
794           The basic colors accepted are normal, black, red, green, yellow,
795           blue, magenta, cyan, white and default. The first color given is
796           the foreground; the second is the background. All the basic colors
797           except normal and default have a bright variant that can be
798           specified by prefixing the color with bright, like brightred.
799
800           The color normal makes no change to the color. It is the same as an
801           empty string, but can be used as the foreground color when
802           specifying a background color alone (for example, "normal red").
803
804           The color default explicitly resets the color to the terminal
805           default, for example to specify a cleared background. Although it
806           varies between terminals, this is usually not the same as setting
807           to "white black".
808
809           Colors may also be given as numbers between 0 and 255; these use
810           ANSI 256-color mode (but note that not all terminals may support
811           this). If your terminal supports it, you may also specify 24-bit
812           RGB values as hex, like #ff0ab3.
813
814           The accepted attributes are bold, dim, ul, blink, reverse, italic,
815           and strike (for crossed-out or "strikethrough" letters). The
816           position of any attributes with respect to the colors (before,
817           after, or in between), doesn’t matter. Specific attributes may be
818           turned off by prefixing them with no or no- (e.g., noreverse,
819           no-ul, etc).
820
821           The pseudo-attribute reset resets all colors and attributes before
822           applying the specified coloring. For example, reset green will
823           result in a green foreground and default background without any
824           active attributes.
825
826           An empty color string produces no color effect at all. This can be
827           used to avoid coloring specific elements without disabling color
828           entirely.
829
830           For git’s pre-defined color slots, the attributes are meant to be
831           reset at the beginning of each item in the colored output. So
832           setting color.decorate.branch to black will paint that branch name
833           in a plain black, even if the previous thing on the same output
834           line (e.g. opening parenthesis before the list of branch names in
835           log --decorate output) is set to be painted with bold or some other
836           attribute. However, custom log formats may do more complicated and
837           layered coloring, and the negated forms may be useful there.
838
839       pathname
840           A variable that takes a pathname value can be given a string that
841           begins with "~/" or "~user/", and the usual tilde expansion happens
842           to such a string: ~/ is expanded to the value of $HOME, and ~user/
843           to the specified user’s home directory.
844
845           If a path starts with %(prefix)/, the remainder is interpreted as a
846           path relative to Git’s "runtime prefix", i.e. relative to the
847           location where Git itself was installed. For example,
848           %(prefix)/bin/ refers to the directory in which the Git executable
849           itself lives. If Git was compiled without runtime prefix support,
850           the compiled-in prefix will be substituted instead. In the unlikely
851           event that a literal path needs to be specified that should not be
852           expanded, it needs to be prefixed by ./, like so: ./%(prefix)/bin.
853
854   Variables
855       Note that this list is non-comprehensive and not necessarily complete.
856       For command-specific variables, you will find a more detailed
857       description in the appropriate manual page.
858
859       Other git-related tools may and do use their own variables. When
860       inventing new variables for use in your own tool, make sure their names
861       do not conflict with those that are used by Git itself and other
862       popular tools, and describe them in your documentation.
863
864       advice.*
865           These variables control various optional help messages designed to
866           aid new users. All advice.*  variables default to true, and you can
867           tell Git that you do not need help by setting these to false:
868
869           ambiguousFetchRefspec
870               Advice shown when a fetch refspec for multiple remotes maps to
871               the same remote-tracking branch namespace and causes branch
872               tracking set-up to fail.
873
874           fetchShowForcedUpdates
875               Advice shown when git-fetch(1) takes a long time to calculate
876               forced updates after ref updates, or to warn that the check is
877               disabled.
878
879           pushUpdateRejected
880               Set this variable to false if you want to disable
881               pushNonFFCurrent, pushNonFFMatching, pushAlreadyExists,
882               pushFetchFirst, pushNeedsForce, and pushRefNeedsUpdate
883               simultaneously.
884
885           pushNonFFCurrent
886               Advice shown when git-push(1) fails due to a non-fast-forward
887               update to the current branch.
888
889           pushNonFFMatching
890               Advice shown when you ran git-push(1) and pushed matching refs
891               explicitly (i.e. you used :, or specified a refspec that isn’t
892               your current branch) and it resulted in a non-fast-forward
893               error.
894
895           pushAlreadyExists
896               Shown when git-push(1) rejects an update that does not qualify
897               for fast-forwarding (e.g., a tag.)
898
899           pushFetchFirst
900               Shown when git-push(1) rejects an update that tries to
901               overwrite a remote ref that points at an object we do not have.
902
903           pushNeedsForce
904               Shown when git-push(1) rejects an update that tries to
905               overwrite a remote ref that points at an object that is not a
906               commit-ish, or make the remote ref point at an object that is
907               not a commit-ish.
908
909           pushUnqualifiedRefname
910               Shown when git-push(1) gives up trying to guess based on the
911               source and destination refs what remote ref namespace the
912               source belongs in, but where we can still suggest that the user
913               push to either refs/heads/* or refs/tags/* based on the type of
914               the source object.
915
916           pushRefNeedsUpdate
917               Shown when git-push(1) rejects a forced update of a branch when
918               its remote-tracking ref has updates that we do not have
919               locally.
920
921           skippedCherryPicks
922               Shown when git-rebase(1) skips a commit that has already been
923               cherry-picked onto the upstream branch.
924
925           statusAheadBehind
926               Shown when git-status(1) computes the ahead/behind counts for a
927               local ref compared to its remote tracking ref, and that
928               calculation takes longer than expected. Will not appear if
929               status.aheadBehind is false or the option --no-ahead-behind is
930               given.
931
932           statusHints
933               Show directions on how to proceed from the current state in the
934               output of git-status(1), in the template shown when writing
935               commit messages in git-commit(1), and in the help message shown
936               by git-switch(1) or git-checkout(1) when switching branches.
937
938           statusUoption
939               Advise to consider using the -u option to git-status(1) when
940               the command takes more than 2 seconds to enumerate untracked
941               files.
942
943           commitBeforeMerge
944               Advice shown when git-merge(1) refuses to merge to avoid
945               overwriting local changes.
946
947           resetNoRefresh
948               Advice to consider using the --no-refresh option to git-
949               reset(1) when the command takes more than 2 seconds to refresh
950               the index after reset.
951
952           resolveConflict
953               Advice shown by various commands when conflicts prevent the
954               operation from being performed.
955
956           sequencerInUse
957               Advice shown when a sequencer command is already in progress.
958
959           implicitIdentity
960               Advice on how to set your identity configuration when your
961               information is guessed from the system username and domain
962               name.
963
964           detachedHead
965               Advice shown when you used git-switch(1) or git-checkout(1) to
966               move to the detached HEAD state, to instruct how to create a
967               local branch after the fact.
968
969           suggestDetachingHead
970               Advice shown when git-switch(1) refuses to detach HEAD without
971               the explicit --detach option.
972
973           checkoutAmbiguousRemoteBranchName
974               Advice shown when the argument to git-checkout(1) and git-
975               switch(1) ambiguously resolves to a remote tracking branch on
976               more than one remote in situations where an unambiguous
977               argument would have otherwise caused a remote-tracking branch
978               to be checked out. See the checkout.defaultRemote configuration
979               variable for how to set a given remote to be used by default in
980               some situations where this advice would be printed.
981
982           amWorkDir
983               Advice that shows the location of the patch file when git-am(1)
984               fails to apply it.
985
986           rmHints
987               In case of failure in the output of git-rm(1), show directions
988               on how to proceed from the current state.
989
990           addEmbeddedRepo
991               Advice on what to do when you’ve accidentally added one git
992               repo inside of another.
993
994           ignoredHook
995               Advice shown if a hook is ignored because the hook is not set
996               as executable.
997
998           waitingForEditor
999               Print a message to the terminal whenever Git is waiting for
1000               editor input from the user.
1001
1002           nestedTag
1003               Advice shown if a user attempts to recursively tag a tag
1004               object.
1005
1006           submoduleAlternateErrorStrategyDie
1007               Advice shown when a submodule.alternateErrorStrategy option
1008               configured to "die" causes a fatal error.
1009
1010           submodulesNotUpdated
1011               Advice shown when a user runs a submodule command that fails
1012               because git submodule update --init was not run.
1013
1014           addIgnoredFile
1015               Advice shown if a user attempts to add an ignored file to the
1016               index.
1017
1018           addEmptyPathspec
1019               Advice shown if a user runs the add command without providing
1020               the pathspec parameter.
1021
1022           updateSparsePath
1023               Advice shown when either git-add(1) or git-rm(1) is asked to
1024               update index entries outside the current sparse checkout.
1025
1026           diverging
1027               Advice shown when a fast-forward is not possible.
1028
1029           worktreeAddOrphan
1030               Advice shown when a user tries to create a worktree from an
1031               invalid reference, to instruct how to create a new orphan
1032               branch instead.
1033
1034       attr.tree
1035           A reference to a tree in the repository from which to read
1036           attributes, instead of the .gitattributes file in the working tree.
1037           In a bare repository, this defaults to HEAD:.gitattributes. If the
1038           value does not resolve to a valid tree object, an empty tree is
1039           used instead. When the GIT_ATTR_SOURCE environment variable or
1040           --attr-source command line option are used, this configuration
1041           variable has no effect.
1042
1043       core.fileMode
1044           Tells Git if the executable bit of files in the working tree is to
1045           be honored.
1046
1047           Some filesystems lose the executable bit when a file that is marked
1048           as executable is checked out, or checks out a non-executable file
1049           with executable bit on.  git-clone(1) or git-init(1) probe the
1050           filesystem to see if it handles the executable bit correctly and
1051           this variable is automatically set as necessary.
1052
1053           A repository, however, may be on a filesystem that handles the
1054           filemode correctly, and this variable is set to true when created,
1055           but later may be made accessible from another environment that
1056           loses the filemode (e.g. exporting ext4 via CIFS mount, visiting a
1057           Cygwin created repository with Git for Windows or Eclipse). In such
1058           a case it may be necessary to set this variable to false. See git-
1059           update-index(1).
1060
1061           The default is true (when core.filemode is not specified in the
1062           config file).
1063
1064       core.hideDotFiles
1065           (Windows-only) If true, mark newly-created directories and files
1066           whose name starts with a dot as hidden. If dotGitOnly, only the
1067           .git/ directory is hidden, but no other files starting with a dot.
1068           The default mode is dotGitOnly.
1069
1070       core.ignoreCase
1071           Internal variable which enables various workarounds to enable Git
1072           to work better on filesystems that are not case sensitive, like
1073           APFS, HFS+, FAT, NTFS, etc. For example, if a directory listing
1074           finds "makefile" when Git expects "Makefile", Git will assume it is
1075           really the same file, and continue to remember it as "Makefile".
1076
1077           The default is false, except git-clone(1) or git-init(1) will probe
1078           and set core.ignoreCase true if appropriate when the repository is
1079           created.
1080
1081           Git relies on the proper configuration of this variable for your
1082           operating and file system. Modifying this value may result in
1083           unexpected behavior.
1084
1085       core.precomposeUnicode
1086           This option is only used by Mac OS implementation of Git. When
1087           core.precomposeUnicode=true, Git reverts the unicode decomposition
1088           of filenames done by Mac OS. This is useful when sharing a
1089           repository between Mac OS and Linux or Windows. (Git for Windows
1090           1.7.10 or higher is needed, or Git under cygwin 1.7). When false,
1091           file names are handled fully transparent by Git, which is backward
1092           compatible with older versions of Git.
1093
1094       core.protectHFS
1095           If set to true, do not allow checkout of paths that would be
1096           considered equivalent to .git on an HFS+ filesystem. Defaults to
1097           true on Mac OS, and false elsewhere.
1098
1099       core.protectNTFS
1100           If set to true, do not allow checkout of paths that would cause
1101           problems with the NTFS filesystem, e.g. conflict with 8.3 "short"
1102           names. Defaults to true on Windows, and false elsewhere.
1103
1104       core.fsmonitor
1105           If set to true, enable the built-in file system monitor daemon for
1106           this working directory (git-fsmonitor--daemon(1)).
1107
1108           Like hook-based file system monitors, the built-in file system
1109           monitor can speed up Git commands that need to refresh the Git
1110           index (e.g.  git status) in a working directory with many files.
1111           The built-in monitor eliminates the need to install and maintain an
1112           external third-party tool.
1113
1114           The built-in file system monitor is currently available only on a
1115           limited set of supported platforms. Currently, this includes
1116           Windows and MacOS.
1117
1118               Otherwise, this variable contains the pathname of the "fsmonitor"
1119               hook command.
1120
1121           This hook command is used to identify all files that may have
1122           changed since the requested date/time. This information is used to
1123           speed up git by avoiding unnecessary scanning of files that have
1124           not changed.
1125
1126           See the "fsmonitor-watchman" section of githooks(5).
1127
1128           Note that if you concurrently use multiple versions of Git, such as
1129           one version on the command line and another version in an IDE tool,
1130           that the definition of core.fsmonitor was extended to allow boolean
1131           values in addition to hook pathnames. Git versions 2.35.1 and prior
1132           will not understand the boolean values and will consider the "true"
1133           or "false" values as hook pathnames to be invoked. Git versions
1134           2.26 thru 2.35.1 default to hook protocol V2 and will fall back to
1135           no fsmonitor (full scan). Git versions prior to 2.26 default to
1136           hook protocol V1 and will silently assume there were no changes to
1137           report (no scan), so status commands may report incomplete results.
1138           For this reason, it is best to upgrade all of your Git versions
1139           before using the built-in file system monitor.
1140
1141       core.fsmonitorHookVersion
1142           Sets the protocol version to be used when invoking the "fsmonitor"
1143           hook.
1144
1145           There are currently versions 1 and 2. When this is not set, version
1146           2 will be tried first and if it fails then version 1 will be tried.
1147           Version 1 uses a timestamp as input to determine which files have
1148           changes since that time but some monitors like Watchman have race
1149           conditions when used with a timestamp. Version 2 uses an opaque
1150           string so that the monitor can return something that can be used to
1151           determine what files have changed without race conditions.
1152
1153       core.trustctime
1154           If false, the ctime differences between the index and the working
1155           tree are ignored; useful when the inode change time is regularly
1156           modified by something outside Git (file system crawlers and some
1157           backup systems). See git-update-index(1). True by default.
1158
1159       core.splitIndex
1160           If true, the split-index feature of the index will be used. See
1161           git-update-index(1). False by default.
1162
1163       core.untrackedCache
1164           Determines what to do about the untracked cache feature of the
1165           index. It will be kept, if this variable is unset or set to keep.
1166           It will automatically be added if set to true. And it will
1167           automatically be removed, if set to false. Before setting it to
1168           true, you should check that mtime is working properly on your
1169           system. See git-update-index(1).  keep by default, unless
1170           feature.manyFiles is enabled which sets this setting to true by
1171           default.
1172
1173       core.checkStat
1174           When missing or is set to default, many fields in the stat
1175           structure are checked to detect if a file has been modified since
1176           Git looked at it. When this configuration variable is set to
1177           minimal, sub-second part of mtime and ctime, the uid and gid of the
1178           owner of the file, the inode number (and the device number, if Git
1179           was compiled to use it), are excluded from the check among these
1180           fields, leaving only the whole-second part of mtime (and ctime, if
1181           core.trustCtime is set) and the filesize to be checked.
1182
1183           There are implementations of Git that do not leave usable values in
1184           some fields (e.g. JGit); by excluding these fields from the
1185           comparison, the minimal mode may help interoperability when the
1186           same repository is used by these other systems at the same time.
1187
1188       core.quotePath
1189           Commands that output paths (e.g.  ls-files, diff), will quote
1190           "unusual" characters in the pathname by enclosing the pathname in
1191           double-quotes and escaping those characters with backslashes in the
1192           same way C escapes control characters (e.g.  \t for TAB, \n for LF,
1193           \\ for backslash) or bytes with values larger than 0x80 (e.g. octal
1194           \302\265 for "micro" in UTF-8). If this variable is set to false,
1195           bytes higher than 0x80 are not considered "unusual" any more.
1196           Double-quotes, backslash and control characters are always escaped
1197           regardless of the setting of this variable. A simple space
1198           character is not considered "unusual". Many commands can output
1199           pathnames completely verbatim using the -z option. The default
1200           value is true.
1201
1202       core.eol
1203           Sets the line ending type to use in the working directory for files
1204           that are marked as text (either by having the text attribute set,
1205           or by having text=auto and Git auto-detecting the contents as
1206           text). Alternatives are lf, crlf and native, which uses the
1207           platform’s native line ending. The default value is native. See
1208           gitattributes(5) for more information on end-of-line conversion.
1209           Note that this value is ignored if core.autocrlf is set to true or
1210           input.
1211
1212       core.safecrlf
1213           If true, makes Git check if converting CRLF is reversible when
1214           end-of-line conversion is active. Git will verify if a command
1215           modifies a file in the work tree either directly or indirectly. For
1216           example, committing a file followed by checking out the same file
1217           should yield the original file in the work tree. If this is not the
1218           case for the current setting of core.autocrlf, Git will reject the
1219           file. The variable can be set to "warn", in which case Git will
1220           only warn about an irreversible conversion but continue the
1221           operation.
1222
1223           CRLF conversion bears a slight chance of corrupting data. When it
1224           is enabled, Git will convert CRLF to LF during commit and LF to
1225           CRLF during checkout. A file that contains a mixture of LF and CRLF
1226           before the commit cannot be recreated by Git. For text files this
1227           is the right thing to do: it corrects line endings such that we
1228           have only LF line endings in the repository. But for binary files
1229           that are accidentally classified as text the conversion can corrupt
1230           data.
1231
1232           If you recognize such corruption early you can easily fix it by
1233           setting the conversion type explicitly in .gitattributes. Right
1234           after committing you still have the original file in your work tree
1235           and this file is not yet corrupted. You can explicitly tell Git
1236           that this file is binary and Git will handle the file
1237           appropriately.
1238
1239           Unfortunately, the desired effect of cleaning up text files with
1240           mixed line endings and the undesired effect of corrupting binary
1241           files cannot be distinguished. In both cases CRLFs are removed in
1242           an irreversible way. For text files this is the right thing to do
1243           because CRLFs are line endings, while for binary files converting
1244           CRLFs corrupts data.
1245
1246           Note, this safety check does not mean that a checkout will generate
1247           a file identical to the original file for a different setting of
1248           core.eol and core.autocrlf, but only for the current one. For
1249           example, a text file with LF would be accepted with core.eol=lf and
1250           could later be checked out with core.eol=crlf, in which case the
1251           resulting file would contain CRLF, although the original file
1252           contained LF. However, in both work trees the line endings would be
1253           consistent, that is either all LF or all CRLF, but never mixed. A
1254           file with mixed line endings would be reported by the core.safecrlf
1255           mechanism.
1256
1257       core.autocrlf
1258           Setting this variable to "true" is the same as setting the text
1259           attribute to "auto" on all files and core.eol to "crlf". Set to
1260           true if you want to have CRLF line endings in your working
1261           directory and the repository has LF line endings. This variable can
1262           be set to input, in which case no output conversion is performed.
1263
1264       core.checkRoundtripEncoding
1265           A comma and/or whitespace separated list of encodings that Git
1266           performs UTF-8 round trip checks on if they are used in an
1267           working-tree-encoding attribute (see gitattributes(5)). The default
1268           value is SHIFT-JIS.
1269
1270       core.symlinks
1271           If false, symbolic links are checked out as small plain files that
1272           contain the link text.  git-update-index(1) and git-add(1) will not
1273           change the recorded type to regular file. Useful on filesystems
1274           like FAT that do not support symbolic links.
1275
1276           The default is true, except git-clone(1) or git-init(1) will probe
1277           and set core.symlinks false if appropriate when the repository is
1278           created.
1279
1280       core.gitProxy
1281           A "proxy command" to execute (as command host port) instead of
1282           establishing direct connection to the remote server when using the
1283           Git protocol for fetching. If the variable value is in the "COMMAND
1284           for DOMAIN" format, the command is applied only on hostnames ending
1285           with the specified domain string. This variable may be set multiple
1286           times and is matched in the given order; the first match wins.
1287
1288           Can be overridden by the GIT_PROXY_COMMAND environment variable
1289           (which always applies universally, without the special "for"
1290           handling).
1291
1292           The special string none can be used as the proxy command to specify
1293           that no proxy be used for a given domain pattern. This is useful
1294           for excluding servers inside a firewall from proxy use, while
1295           defaulting to a common proxy for external domains.
1296
1297       core.sshCommand
1298           If this variable is set, git fetch and git push will use the
1299           specified command instead of ssh when they need to connect to a
1300           remote system. The command is in the same form as the
1301           GIT_SSH_COMMAND environment variable and is overridden when the
1302           environment variable is set.
1303
1304       core.ignoreStat
1305           If true, Git will avoid using lstat() calls to detect if files have
1306           changed by setting the "assume-unchanged" bit for those tracked
1307           files which it has updated identically in both the index and
1308           working tree.
1309
1310           When files are modified outside of Git, the user will need to stage
1311           the modified files explicitly (e.g. see Examples section in git-
1312           update-index(1)). Git will not normally detect changes to those
1313           files.
1314
1315           This is useful on systems where lstat() calls are very slow, such
1316           as CIFS/Microsoft Windows.
1317
1318           False by default.
1319
1320       core.preferSymlinkRefs
1321           Instead of the default "symref" format for HEAD and other symbolic
1322           reference files, use symbolic links. This is sometimes needed to
1323           work with old scripts that expect HEAD to be a symbolic link.
1324
1325       core.alternateRefsCommand
1326           When advertising tips of available history from an alternate, use
1327           the shell to execute the specified command instead of git-for-each-
1328           ref(1). The first argument is the absolute path of the alternate.
1329           Output must contain one hex object id per line (i.e., the same as
1330           produced by git for-each-ref --format='%(objectname)').
1331
1332           Note that you cannot generally put git for-each-ref directly into
1333           the config value, as it does not take a repository path as an
1334           argument (but you can wrap the command above in a shell script).
1335
1336       core.alternateRefsPrefixes
1337           When listing references from an alternate, list only references
1338           that begin with the given prefix. Prefixes match as if they were
1339           given as arguments to git-for-each-ref(1). To list multiple
1340           prefixes, separate them with whitespace. If
1341           core.alternateRefsCommand is set, setting
1342           core.alternateRefsPrefixes has no effect.
1343
1344       core.bare
1345           If true this repository is assumed to be bare and has no working
1346           directory associated with it. If this is the case a number of
1347           commands that require a working directory will be disabled, such as
1348           git-add(1) or git-merge(1).
1349
1350           This setting is automatically guessed by git-clone(1) or git-
1351           init(1) when the repository was created. By default a repository
1352           that ends in "/.git" is assumed to be not bare (bare = false),
1353           while all other repositories are assumed to be bare (bare = true).
1354
1355       core.worktree
1356           Set the path to the root of the working tree. If GIT_COMMON_DIR
1357           environment variable is set, core.worktree is ignored and not used
1358           for determining the root of working tree. This can be overridden by
1359           the GIT_WORK_TREE environment variable and the --work-tree
1360           command-line option. The value can be an absolute path or relative
1361           to the path to the .git directory, which is either specified by
1362           --git-dir or GIT_DIR, or automatically discovered. If --git-dir or
1363           GIT_DIR is specified but none of --work-tree, GIT_WORK_TREE and
1364           core.worktree is specified, the current working directory is
1365           regarded as the top level of your working tree.
1366
1367           Note that this variable is honored even when set in a configuration
1368           file in a ".git" subdirectory of a directory and its value differs
1369           from the latter directory (e.g. "/path/to/.git/config" has
1370           core.worktree set to "/different/path"), which is most likely a
1371           misconfiguration. Running Git commands in the "/path/to" directory
1372           will still use "/different/path" as the root of the work tree and
1373           can cause confusion unless you know what you are doing (e.g. you
1374           are creating a read-only snapshot of the same index to a location
1375           different from the repository’s usual working tree).
1376
1377       core.logAllRefUpdates
1378           Enable the reflog. Updates to a ref <ref> is logged to the file
1379           "$GIT_DIR/logs/<ref>", by appending the new and old SHA-1, the
1380           date/time and the reason of the update, but only when the file
1381           exists. If this configuration variable is set to true, missing
1382           "$GIT_DIR/logs/<ref>" file is automatically created for branch
1383           heads (i.e. under refs/heads/), remote refs (i.e. under
1384           refs/remotes/), note refs (i.e. under refs/notes/), and the
1385           symbolic ref HEAD. If it is set to always, then a missing reflog is
1386           automatically created for any ref under refs/.
1387
1388           This information can be used to determine what commit was the tip
1389           of a branch "2 days ago".
1390
1391           This value is true by default in a repository that has a working
1392           directory associated with it, and false by default in a bare
1393           repository.
1394
1395       core.repositoryFormatVersion
1396           Internal variable identifying the repository format and layout
1397           version.
1398
1399       core.sharedRepository
1400           When group (or true), the repository is made shareable between
1401           several users in a group (making sure all the files and objects are
1402           group-writable). When all (or world or everybody), the repository
1403           will be readable by all users, additionally to being
1404           group-shareable. When umask (or false), Git will use permissions
1405           reported by umask(2). When 0xxx, where 0xxx is an octal number,
1406           files in the repository will have this mode value.  0xxx will
1407           override user’s umask value (whereas the other options will only
1408           override requested parts of the user’s umask value). Examples: 0660
1409           will make the repo read/write-able for the owner and group, but
1410           inaccessible to others (equivalent to group unless umask is e.g.
1411           0022).  0640 is a repository that is group-readable but not
1412           group-writable. See git-init(1). False by default.
1413
1414       core.warnAmbiguousRefs
1415           If true, Git will warn you if the ref name you passed it is
1416           ambiguous and might match multiple refs in the repository. True by
1417           default.
1418
1419       core.compression
1420           An integer -1..9, indicating a default compression level. -1 is the
1421           zlib default. 0 means no compression, and 1..9 are various
1422           speed/size tradeoffs, 9 being slowest. If set, this provides a
1423           default to other compression variables, such as
1424           core.looseCompression and pack.compression.
1425
1426       core.looseCompression
1427           An integer -1..9, indicating the compression level for objects that
1428           are not in a pack file. -1 is the zlib default. 0 means no
1429           compression, and 1..9 are various speed/size tradeoffs, 9 being
1430           slowest. If not set, defaults to core.compression. If that is not
1431           set, defaults to 1 (best speed).
1432
1433       core.packedGitWindowSize
1434           Number of bytes of a pack file to map into memory in a single
1435           mapping operation. Larger window sizes may allow your system to
1436           process a smaller number of large pack files more quickly. Smaller
1437           window sizes will negatively affect performance due to increased
1438           calls to the operating system’s memory manager, but may improve
1439           performance when accessing a large number of large pack files.
1440
1441           Default is 1 MiB if NO_MMAP was set at compile time, otherwise 32
1442           MiB on 32 bit platforms and 1 GiB on 64 bit platforms. This should
1443           be reasonable for all users/operating systems. You probably do not
1444           need to adjust this value.
1445
1446           Common unit suffixes of k, m, or g are supported.
1447
1448       core.packedGitLimit
1449           Maximum number of bytes to map simultaneously into memory from pack
1450           files. If Git needs to access more than this many bytes at once to
1451           complete an operation it will unmap existing regions to reclaim
1452           virtual address space within the process.
1453
1454           Default is 256 MiB on 32 bit platforms and 32 TiB (effectively
1455           unlimited) on 64 bit platforms. This should be reasonable for all
1456           users/operating systems, except on the largest projects. You
1457           probably do not need to adjust this value.
1458
1459           Common unit suffixes of k, m, or g are supported.
1460
1461       core.deltaBaseCacheLimit
1462           Maximum number of bytes per thread to reserve for caching base
1463           objects that may be referenced by multiple deltified objects. By
1464           storing the entire decompressed base objects in a cache Git is able
1465           to avoid unpacking and decompressing frequently used base objects
1466           multiple times.
1467
1468           Default is 96 MiB on all platforms. This should be reasonable for
1469           all users/operating systems, except on the largest projects. You
1470           probably do not need to adjust this value.
1471
1472           Common unit suffixes of k, m, or g are supported.
1473
1474       core.bigFileThreshold
1475           The size of files considered "big", which as discussed below
1476           changes the behavior of numerous git commands, as well as how such
1477           files are stored within the repository. The default is 512 MiB.
1478           Common unit suffixes of k, m, or g are supported.
1479
1480           Files above the configured limit will be:
1481
1482           •   Stored deflated in packfiles, without attempting delta
1483               compression.
1484
1485               The default limit is primarily set with this use-case in mind.
1486               With it, most projects will have their source code and other
1487               text files delta compressed, but not larger binary media files.
1488
1489               Storing large files without delta compression avoids excessive
1490               memory usage, at the slight expense of increased disk usage.
1491
1492           •   Will be treated as if they were labeled "binary" (see
1493               gitattributes(5)). e.g.  git-log(1) and git-diff(1) will not
1494               compute diffs for files above this limit.
1495
1496           •   Will generally be streamed when written, which avoids excessive
1497               memory usage, at the cost of some fixed overhead. Commands that
1498               make use of this include git-archive(1), git-fast-import(1),
1499               git-index-pack(1), git-unpack-objects(1) and git-fsck(1).
1500
1501       core.excludesFile
1502           Specifies the pathname to the file that contains patterns to
1503           describe paths that are not meant to be tracked, in addition to
1504           .gitignore (per-directory) and .git/info/exclude. Defaults to
1505           $XDG_CONFIG_HOME/git/ignore. If $XDG_CONFIG_HOME is either not set
1506           or empty, $HOME/.config/git/ignore is used instead. See
1507           gitignore(5).
1508
1509       core.askPass
1510           Some commands (e.g. svn and http interfaces) that interactively ask
1511           for a password can be told to use an external program given via the
1512           value of this variable. Can be overridden by the GIT_ASKPASS
1513           environment variable. If not set, fall back to the value of the
1514           SSH_ASKPASS environment variable or, failing that, a simple
1515           password prompt. The external program shall be given a suitable
1516           prompt as command-line argument and write the password on its
1517           STDOUT.
1518
1519       core.attributesFile
1520           In addition to .gitattributes (per-directory) and
1521           .git/info/attributes, Git looks into this file for attributes (see
1522           gitattributes(5)). Path expansions are made the same way as for
1523           core.excludesFile. Its default value is
1524           $XDG_CONFIG_HOME/git/attributes. If $XDG_CONFIG_HOME is either not
1525           set or empty, $HOME/.config/git/attributes is used instead.
1526
1527       core.hooksPath
1528           By default Git will look for your hooks in the $GIT_DIR/hooks
1529           directory. Set this to different path, e.g.  /etc/git/hooks, and
1530           Git will try to find your hooks in that directory, e.g.
1531           /etc/git/hooks/pre-receive instead of in
1532           $GIT_DIR/hooks/pre-receive.
1533
1534           The path can be either absolute or relative. A relative path is
1535           taken as relative to the directory where the hooks are run (see the
1536           "DESCRIPTION" section of githooks(5)).
1537
1538           This configuration variable is useful in cases where you’d like to
1539           centrally configure your Git hooks instead of configuring them on a
1540           per-repository basis, or as a more flexible and centralized
1541           alternative to having an init.templateDir where you’ve changed
1542           default hooks.
1543
1544       core.editor
1545           Commands such as commit and tag that let you edit messages by
1546           launching an editor use the value of this variable when it is set,
1547           and the environment variable GIT_EDITOR is not set. See git-var(1).
1548
1549       core.commentChar
1550           Commands such as commit and tag that let you edit messages consider
1551           a line that begins with this character commented, and removes them
1552           after the editor returns (default #).
1553
1554           If set to "auto", git-commit would select a character that is not
1555           the beginning character of any line in existing commit messages.
1556
1557       core.filesRefLockTimeout
1558           The length of time, in milliseconds, to retry when trying to lock
1559           an individual reference. Value 0 means not to retry at all; -1
1560           means to try indefinitely. Default is 100 (i.e., retry for 100ms).
1561
1562       core.packedRefsTimeout
1563           The length of time, in milliseconds, to retry when trying to lock
1564           the packed-refs file. Value 0 means not to retry at all; -1 means
1565           to try indefinitely. Default is 1000 (i.e., retry for 1 second).
1566
1567       core.pager
1568           Text viewer for use by Git commands (e.g., less). The value is
1569           meant to be interpreted by the shell. The order of preference is
1570           the $GIT_PAGER environment variable, then core.pager configuration,
1571           then $PAGER, and then the default chosen at compile time (usually
1572           less).
1573
1574           When the LESS environment variable is unset, Git sets it to FRX (if
1575           LESS environment variable is set, Git does not change it at all).
1576           If you want to selectively override Git’s default setting for LESS,
1577           you can set core.pager to e.g.  less -S. This will be passed to the
1578           shell by Git, which will translate the final command to LESS=FRX
1579           less -S. The environment does not set the S option but the command
1580           line does, instructing less to truncate long lines. Similarly,
1581           setting core.pager to less -+F will deactivate the F option
1582           specified by the environment from the command-line, deactivating
1583           the "quit if one screen" behavior of less. One can specifically
1584           activate some flags for particular commands: for example, setting
1585           pager.blame to less -S enables line truncation only for git blame.
1586
1587           Likewise, when the LV environment variable is unset, Git sets it to
1588           -c. You can override this setting by exporting LV with another
1589           value or setting core.pager to lv +c.
1590
1591       core.whitespace
1592           A comma separated list of common whitespace problems to notice.
1593           git diff will use color.diff.whitespace to highlight them, and git
1594           apply --whitespace=error will consider them as errors. You can
1595           prefix - to disable any of them (e.g.  -trailing-space):
1596
1597blank-at-eol treats trailing whitespaces at the end of the line
1598               as an error (enabled by default).
1599
1600space-before-tab treats a space character that appears
1601               immediately before a tab character in the initial indent part
1602               of the line as an error (enabled by default).
1603
1604indent-with-non-tab treats a line that is indented with space
1605               characters instead of the equivalent tabs as an error (not
1606               enabled by default).
1607
1608tab-in-indent treats a tab character in the initial indent part
1609               of the line as an error (not enabled by default).
1610
1611blank-at-eof treats blank lines added at the end of file as an
1612               error (enabled by default).
1613
1614trailing-space is a short-hand to cover both blank-at-eol and
1615               blank-at-eof.
1616
1617cr-at-eol treats a carriage-return at the end of line as part
1618               of the line terminator, i.e. with it, trailing-space does not
1619               trigger if the character before such a carriage-return is not a
1620               whitespace (not enabled by default).
1621
1622tabwidth=<n> tells how many character positions a tab occupies;
1623               this is relevant for indent-with-non-tab and when Git fixes
1624               tab-in-indent errors. The default tab width is 8. Allowed
1625               values are 1 to 63.
1626
1627       core.fsync
1628           A comma-separated list of components of the repository that should
1629           be hardened via the core.fsyncMethod when created or modified. You
1630           can disable hardening of any component by prefixing it with a -.
1631           Items that are not hardened may be lost in the event of an unclean
1632           system shutdown. Unless you have special requirements, it is
1633           recommended that you leave this option empty or pick one of
1634           committed, added, or all.
1635
1636           When this configuration is encountered, the set of components
1637           starts with the platform default value, disabled components are
1638           removed, and additional components are added.  none resets the
1639           state so that the platform default is ignored.
1640
1641           The empty string resets the fsync configuration to the platform
1642           default. The default on most platforms is equivalent to
1643           core.fsync=committed,-loose-object, which has good performance, but
1644           risks losing recent work in the event of an unclean system
1645           shutdown.
1646
1647none clears the set of fsynced components.
1648
1649loose-object hardens objects added to the repo in loose-object
1650               form.
1651
1652pack hardens objects added to the repo in packfile form.
1653
1654pack-metadata hardens packfile bitmaps and indexes.
1655
1656commit-graph hardens the commit-graph file.
1657
1658index hardens the index when it is modified.
1659
1660objects is an aggregate option that is equivalent to
1661               loose-object,pack.
1662
1663reference hardens references modified in the repo.
1664
1665derived-metadata is an aggregate option that is equivalent to
1666               pack-metadata,commit-graph.
1667
1668committed is an aggregate option that is currently equivalent
1669               to objects. This mode sacrifices some performance to ensure
1670               that work that is committed to the repository with git commit
1671               or similar commands is hardened.
1672
1673added is an aggregate option that is currently equivalent to
1674               committed,index. This mode sacrifices additional performance to
1675               ensure that the results of commands like git add and similar
1676               operations are hardened.
1677
1678all is an aggregate option that syncs all individual components
1679               above.
1680
1681       core.fsyncMethod
1682           A value indicating the strategy Git will use to harden repository
1683           data using fsync and related primitives.
1684
1685fsync uses the fsync() system call or platform equivalents.
1686
1687writeout-only issues pagecache writeback requests, but
1688               depending on the filesystem and storage hardware, data added to
1689               the repository may not be durable in the event of a system
1690               crash. This is the default mode on macOS.
1691
1692batch enables a mode that uses writeout-only flushes to stage
1693               multiple updates in the disk writeback cache and then does a
1694               single full fsync of a dummy file to trigger the disk cache
1695               flush at the end of the operation.
1696
1697               Currently batch mode only applies to loose-object files. Other
1698               repository data is made durable as if fsync was specified. This
1699               mode is expected to be as safe as fsync on macOS for repos
1700               stored on HFS+ or APFS filesystems and on Windows for repos
1701               stored on NTFS or ReFS filesystems.
1702
1703       core.fsyncObjectFiles
1704           This boolean will enable fsync() when writing object files. This
1705           setting is deprecated. Use core.fsync instead.
1706
1707           This setting affects data added to the Git repository in
1708           loose-object form. When set to true, Git will issue an fsync or
1709           similar system call to flush caches so that loose-objects remain
1710           consistent in the face of a unclean system shutdown.
1711
1712       core.preloadIndex
1713           Enable parallel index preload for operations like git diff
1714
1715           This can speed up operations like git diff and git status
1716           especially on filesystems like NFS that have weak caching semantics
1717           and thus relatively high IO latencies. When enabled, Git will do
1718           the index comparison to the filesystem data in parallel, allowing
1719           overlapping IO’s. Defaults to true.
1720
1721       core.unsetenvvars
1722           Windows-only: comma-separated list of environment variables' names
1723           that need to be unset before spawning any other process. Defaults
1724           to PERL5LIB to account for the fact that Git for Windows insists on
1725           using its own Perl interpreter.
1726
1727       core.restrictinheritedhandles
1728           Windows-only: override whether spawned processes inherit only
1729           standard file handles (stdin, stdout and stderr) or all handles.
1730           Can be auto, true or false. Defaults to auto, which means true on
1731           Windows 7 and later, and false on older Windows versions.
1732
1733       core.createObject
1734           You can set this to link, in which case a hardlink followed by a
1735           delete of the source are used to make sure that object creation
1736           will not overwrite existing objects.
1737
1738           On some file system/operating system combinations, this is
1739           unreliable. Set this config setting to rename there; However, This
1740           will remove the check that makes sure that existing object files
1741           will not get overwritten.
1742
1743       core.notesRef
1744           When showing commit messages, also show notes which are stored in
1745           the given ref. The ref must be fully qualified. If the given ref
1746           does not exist, it is not an error but means that no notes should
1747           be printed.
1748
1749           This setting defaults to "refs/notes/commits", and it can be
1750           overridden by the GIT_NOTES_REF environment variable. See git-
1751           notes(1).
1752
1753       core.commitGraph
1754           If true, then git will read the commit-graph file (if it exists) to
1755           parse the graph structure of commits. Defaults to true. See git-
1756           commit-graph(1) for more information.
1757
1758       core.useReplaceRefs
1759           If set to false, behave as if the --no-replace-objects option was
1760           given on the command line. See git(1) and git-replace(1) for more
1761           information.
1762
1763       core.multiPackIndex
1764           Use the multi-pack-index file to track multiple packfiles using a
1765           single index. See git-multi-pack-index(1) for more information.
1766           Defaults to true.
1767
1768       core.sparseCheckout
1769           Enable "sparse checkout" feature. See git-sparse-checkout(1) for
1770           more information.
1771
1772       core.sparseCheckoutCone
1773           Enables the "cone mode" of the sparse checkout feature. When the
1774           sparse-checkout file contains a limited set of patterns, this mode
1775           provides significant performance advantages. The "non-cone mode"
1776           can be requested to allow specifying more flexible patterns by
1777           setting this variable to false. See git-sparse-checkout(1) for more
1778           information.
1779
1780       core.abbrev
1781           Set the length object names are abbreviated to. If unspecified or
1782           set to "auto", an appropriate value is computed based on the
1783           approximate number of packed objects in your repository, which
1784           hopefully is enough for abbreviated object names to stay unique for
1785           some time. If set to "no", no abbreviation is made and the object
1786           names are shown in their full length. The minimum length is 4.
1787
1788       core.maxTreeDepth
1789           The maximum depth Git is willing to recurse while traversing a tree
1790           (e.g., "a/b/cde/f" has a depth of 4). This is a fail-safe to allow
1791           Git to abort cleanly, and should not generally need to be adjusted.
1792           The default is 4096.
1793
1794       add.ignoreErrors, add.ignore-errors (deprecated)
1795           Tells git add to continue adding files when some files cannot be
1796           added due to indexing errors. Equivalent to the --ignore-errors
1797           option of git-add(1).  add.ignore-errors is deprecated, as it does
1798           not follow the usual naming convention for configuration variables.
1799
1800       add.interactive.useBuiltin
1801           Unused configuration variable. Used in Git versions v2.25.0 to
1802           v2.36.0 to enable the built-in version of git-add(1)'s interactive
1803           mode, which then became the default in Git versions v2.37.0 to
1804           v2.39.0.
1805
1806       alias.*
1807           Command aliases for the git(1) command wrapper - e.g. after
1808           defining alias.last = cat-file commit HEAD, the invocation git last
1809           is equivalent to git cat-file commit HEAD. To avoid confusion and
1810           troubles with script usage, aliases that hide existing Git commands
1811           are ignored. Arguments are split by spaces, the usual shell quoting
1812           and escaping are supported. A quote pair or a backslash can be used
1813           to quote them.
1814
1815           Note that the first word of an alias does not necessarily have to
1816           be a command. It can be a command-line option that will be passed
1817           into the invocation of git. In particular, this is useful when used
1818           with -c to pass in one-time configurations or -p to force
1819           pagination. For example, loud-rebase = -c commit.verbose=true
1820           rebase can be defined such that running git loud-rebase would be
1821           equivalent to git -c commit.verbose=true rebase. Also, ps = -p
1822           status would be a helpful alias since git ps would paginate the
1823           output of git status where the original command does not.
1824
1825           If the alias expansion is prefixed with an exclamation point, it
1826           will be treated as a shell command. For example, defining alias.new
1827           = !gitk --all --not ORIG_HEAD, the invocation git new is equivalent
1828           to running the shell command gitk --all --not ORIG_HEAD. Note that
1829           shell commands will be executed from the top-level directory of a
1830           repository, which may not necessarily be the current directory.
1831           GIT_PREFIX is set as returned by running git rev-parse
1832           --show-prefix from the original current directory. See git-rev-
1833           parse(1).
1834
1835       am.keepcr
1836           If true, git-am will call git-mailsplit for patches in mbox format
1837           with parameter --keep-cr. In this case git-mailsplit will not
1838           remove \r from lines ending with \r\n. Can be overridden by giving
1839           --no-keep-cr from the command line. See git-am(1), git-
1840           mailsplit(1).
1841
1842       am.threeWay
1843           By default, git am will fail if the patch does not apply cleanly.
1844           When set to true, this setting tells git am to fall back on 3-way
1845           merge if the patch records the identity of blobs it is supposed to
1846           apply to and we have those blobs available locally (equivalent to
1847           giving the --3way option from the command line). Defaults to false.
1848           See git-am(1).
1849
1850       apply.ignoreWhitespace
1851           When set to change, tells git apply to ignore changes in
1852           whitespace, in the same way as the --ignore-space-change option.
1853           When set to one of: no, none, never, false, it tells git apply to
1854           respect all whitespace differences. See git-apply(1).
1855
1856       apply.whitespace
1857           Tells git apply how to handle whitespace, in the same way as the
1858           --whitespace option. See git-apply(1).
1859
1860       blame.blankBoundary
1861           Show blank commit object name for boundary commits in git-blame(1).
1862           This option defaults to false.
1863
1864       blame.coloring
1865           This determines the coloring scheme to be applied to blame output.
1866           It can be repeatedLines, highlightRecent, or none which is the
1867           default.
1868
1869       blame.date
1870           Specifies the format used to output dates in git-blame(1). If unset
1871           the iso format is used. For supported values, see the discussion of
1872           the --date option at git-log(1).
1873
1874       blame.showEmail
1875           Show the author email instead of author name in git-blame(1). This
1876           option defaults to false.
1877
1878       blame.showRoot
1879           Do not treat root commits as boundaries in git-blame(1). This
1880           option defaults to false.
1881
1882       blame.ignoreRevsFile
1883           Ignore revisions listed in the file, one unabbreviated object name
1884           per line, in git-blame(1). Whitespace and comments beginning with #
1885           are ignored. This option may be repeated multiple times. Empty file
1886           names will reset the list of ignored revisions. This option will be
1887           handled before the command line option --ignore-revs-file.
1888
1889       blame.markUnblamableLines
1890           Mark lines that were changed by an ignored revision that we could
1891           not attribute to another commit with a * in the output of git-
1892           blame(1).
1893
1894       blame.markIgnoredLines
1895           Mark lines that were changed by an ignored revision that we
1896           attributed to another commit with a ?  in the output of git-
1897           blame(1).
1898
1899       branch.autoSetupMerge
1900           Tells git branch, git switch and git checkout to set up new
1901           branches so that git-pull(1) will appropriately merge from the
1902           starting point branch. Note that even if this option is not set,
1903           this behavior can be chosen per-branch using the --track and
1904           --no-track options. The valid settings are: false — no automatic
1905           setup is done; true — automatic setup is done when the starting
1906           point is a remote-tracking branch; always — automatic setup is done
1907           when the starting point is either a local branch or remote-tracking
1908           branch; inherit — if the starting point has a tracking
1909           configuration, it is copied to the new branch; simple — automatic
1910           setup is done only when the starting point is a remote-tracking
1911           branch and the new branch has the same name as the remote branch.
1912           This option defaults to true.
1913
1914       branch.autoSetupRebase
1915           When a new branch is created with git branch, git switch or git
1916           checkout that tracks another branch, this variable tells Git to set
1917           up pull to rebase instead of merge (see "branch.<name>.rebase").
1918           When never, rebase is never automatically set to true. When local,
1919           rebase is set to true for tracked branches of other local branches.
1920           When remote, rebase is set to true for tracked branches of
1921           remote-tracking branches. When always, rebase will be set to true
1922           for all tracking branches. See "branch.autoSetupMerge" for details
1923           on how to set up a branch to track another branch. This option
1924           defaults to never.
1925
1926       branch.sort
1927           This variable controls the sort ordering of branches when displayed
1928           by git-branch(1). Without the "--sort=<value>" option provided, the
1929           value of this variable will be used as the default. See git-for-
1930           each-ref(1) field names for valid values.
1931
1932       branch.<name>.remote
1933           When on branch <name>, it tells git fetch and git push which remote
1934           to fetch from or push to. The remote to push to may be overridden
1935           with remote.pushDefault (for all branches). The remote to push to,
1936           for the current branch, may be further overridden by
1937           branch.<name>.pushRemote. If no remote is configured, or if you are
1938           not on any branch and there is more than one remote defined in the
1939           repository, it defaults to origin for fetching and
1940           remote.pushDefault for pushing. Additionally, .  (a period) is the
1941           current local repository (a dot-repository), see
1942           branch.<name>.merge's final note below.
1943
1944       branch.<name>.pushRemote
1945           When on branch <name>, it overrides branch.<name>.remote for
1946           pushing. It also overrides remote.pushDefault for pushing from
1947           branch <name>. When you pull from one place (e.g. your upstream)
1948           and push to another place (e.g. your own publishing repository),
1949           you would want to set remote.pushDefault to specify the remote to
1950           push to for all branches, and use this option to override it for a
1951           specific branch.
1952
1953       branch.<name>.merge
1954           Defines, together with branch.<name>.remote, the upstream branch
1955           for the given branch. It tells git fetch/git pull/git rebase which
1956           branch to merge and can also affect git push (see push.default).
1957           When in branch <name>, it tells git fetch the default refspec to be
1958           marked for merging in FETCH_HEAD. The value is handled like the
1959           remote part of a refspec, and must match a ref which is fetched
1960           from the remote given by "branch.<name>.remote". The merge
1961           information is used by git pull (which first calls git fetch) to
1962           lookup the default branch for merging. Without this option, git
1963           pull defaults to merge the first refspec fetched. Specify multiple
1964           values to get an octopus merge. If you wish to setup git pull so
1965           that it merges into <name> from another branch in the local
1966           repository, you can point branch.<name>.merge to the desired
1967           branch, and use the relative path setting .  (a period) for
1968           branch.<name>.remote.
1969
1970       branch.<name>.mergeOptions
1971           Sets default options for merging into branch <name>. The syntax and
1972           supported options are the same as those of git-merge(1), but option
1973           values containing whitespace characters are currently not
1974           supported.
1975
1976       branch.<name>.rebase
1977           When true, rebase the branch <name> on top of the fetched branch,
1978           instead of merging the default branch from the default remote when
1979           "git pull" is run. See "pull.rebase" for doing this in a non
1980           branch-specific manner.
1981
1982           When merges (or just m), pass the --rebase-merges option to git
1983           rebase so that the local merge commits are included in the rebase
1984           (see git-rebase(1) for details).
1985
1986           When the value is interactive (or just i), the rebase is run in
1987           interactive mode.
1988
1989           NOTE: this is a possibly dangerous operation; do not use it unless
1990           you understand the implications (see git-rebase(1) for details).
1991
1992       branch.<name>.description
1993           Branch description, can be edited with git branch
1994           --edit-description. Branch description is automatically added to
1995           the format-patch cover letter or request-pull summary.
1996
1997       browser.<tool>.cmd
1998           Specify the command to invoke the specified browser. The specified
1999           command is evaluated in shell with the URLs passed as arguments.
2000           (See git-web--browse(1).)
2001
2002       browser.<tool>.path
2003           Override the path for the given tool that may be used to browse
2004           HTML help (see -w option in git-help(1)) or a working repository in
2005           gitweb (see git-instaweb(1)).
2006
2007       bundle.*
2008           The bundle.*  keys may appear in a bundle list file found via the
2009           git clone --bundle-uri option. These keys currently have no effect
2010           if placed in a repository config file, though this will change in
2011           the future. See the bundle URI design document[1] for more details.
2012
2013       bundle.version
2014           This integer value advertises the version of the bundle list format
2015           used by the bundle list. Currently, the only accepted value is 1.
2016
2017       bundle.mode
2018           This string value should be either all or any. This value describes
2019           whether all of the advertised bundles are required to unbundle a
2020           complete understanding of the bundled information (all) or if any
2021           one of the listed bundle URIs is sufficient (any).
2022
2023       bundle.heuristic
2024           If this string-valued key exists, then the bundle list is designed
2025           to work well with incremental git fetch commands. The heuristic
2026           signals that there are additional keys available for each bundle
2027           that help determine which subset of bundles the client should
2028           download. The only value currently understood is creationToken.
2029
2030       bundle.<id>.*
2031           The bundle.<id>.*  keys are used to describe a single item in the
2032           bundle list, grouped under <id> for identification purposes.
2033
2034       bundle.<id>.uri
2035           This string value defines the URI by which Git can reach the
2036           contents of this <id>. This URI may be a bundle file or another
2037           bundle list.
2038
2039       checkout.defaultRemote
2040           When you run git checkout <something> or git switch <something> and
2041           only have one remote, it may implicitly fall back on checking out
2042           and tracking e.g.  origin/<something>. This stops working as soon
2043           as you have more than one remote with a <something> reference. This
2044           setting allows for setting the name of a preferred remote that
2045           should always win when it comes to disambiguation. The typical
2046           use-case is to set this to origin.
2047
2048           Currently this is used by git-switch(1) and git-checkout(1) when
2049           git checkout <something> or git switch <something> will checkout
2050           the <something> branch on another remote, and by git-worktree(1)
2051           when git worktree add refers to a remote branch. This setting might
2052           be used for other checkout-like commands or functionality in the
2053           future.
2054
2055       checkout.guess
2056           Provides the default value for the --guess or --no-guess option in
2057           git checkout and git switch. See git-switch(1) and git-checkout(1).
2058
2059       checkout.workers
2060           The number of parallel workers to use when updating the working
2061           tree. The default is one, i.e. sequential execution. If set to a
2062           value less than one, Git will use as many workers as the number of
2063           logical cores available. This setting and
2064           checkout.thresholdForParallelism affect all commands that perform
2065           checkout. E.g. checkout, clone, reset, sparse-checkout, etc.
2066
2067           Note: Parallel checkout usually delivers better performance for
2068           repositories located on SSDs or over NFS. For repositories on
2069           spinning disks and/or machines with a small number of cores, the
2070           default sequential checkout often performs better. The size and
2071           compression level of a repository might also influence how well the
2072           parallel version performs.
2073
2074       checkout.thresholdForParallelism
2075           When running parallel checkout with a small number of files, the
2076           cost of subprocess spawning and inter-process communication might
2077           outweigh the parallelization gains. This setting allows you to
2078           define the minimum number of files for which parallel checkout
2079           should be attempted. The default is 100.
2080
2081       clean.requireForce
2082           A boolean to make git-clean do nothing unless given -f, -i, or -n.
2083           Defaults to true.
2084
2085       clone.defaultRemoteName
2086           The name of the remote to create when cloning a repository.
2087           Defaults to origin, and can be overridden by passing the --origin
2088           command-line option to git-clone(1).
2089
2090       clone.rejectShallow
2091           Reject cloning a repository if it is a shallow one; this can be
2092           overridden by passing the --reject-shallow option on the command
2093           line. See git-clone(1)
2094
2095       clone.filterSubmodules
2096           If a partial clone filter is provided (see --filter in git-rev-
2097           list(1)) and --recurse-submodules is used, also apply the filter to
2098           submodules.
2099
2100       color.advice
2101           A boolean to enable/disable color in hints (e.g. when a push
2102           failed, see advice.*  for a list). May be set to always, false (or
2103           never) or auto (or true), in which case colors are used only when
2104           the error output goes to a terminal. If unset, then the value of
2105           color.ui is used (auto by default).
2106
2107       color.advice.hint
2108           Use customized color for hints.
2109
2110       color.blame.highlightRecent
2111           Specify the line annotation color for git blame --color-by-age
2112           depending upon the age of the line.
2113
2114           This setting should be set to a comma-separated list of color and
2115           date settings, starting and ending with a color, the dates should
2116           be set from oldest to newest. The metadata will be colored with the
2117           specified colors if the line was introduced before the given
2118           timestamp, overwriting older timestamped colors.
2119
2120           Instead of an absolute timestamp relative timestamps work as well,
2121           e.g.  2.weeks.ago is valid to address anything older than 2 weeks.
2122
2123           It defaults to blue,12 month ago,white,1 month ago,red, which
2124           colors everything older than one year blue, recent changes between
2125           one month and one year old are kept white, and lines introduced
2126           within the last month are colored red.
2127
2128       color.blame.repeatedLines
2129           Use the specified color to colorize line annotations for git blame
2130           --color-lines, if they come from the same commit as the preceding
2131           line. Defaults to cyan.
2132
2133       color.branch
2134           A boolean to enable/disable color in the output of git-branch(1).
2135           May be set to always, false (or never) or auto (or true), in which
2136           case colors are used only when the output is to a terminal. If
2137           unset, then the value of color.ui is used (auto by default).
2138
2139       color.branch.<slot>
2140           Use customized color for branch coloration.  <slot> is one of
2141           current (the current branch), local (a local branch), remote (a
2142           remote-tracking branch in refs/remotes/), upstream (upstream
2143           tracking branch), plain (other refs).
2144
2145       color.diff
2146           Whether to use ANSI escape sequences to add color to patches. If
2147           this is set to always, git-diff(1), git-log(1), and git-show(1)
2148           will use color for all patches. If it is set to true or auto, those
2149           commands will only use color when output is to the terminal. If
2150           unset, then the value of color.ui is used (auto by default).
2151
2152           This does not affect git-format-patch(1) or the git-diff-* plumbing
2153           commands. Can be overridden on the command line with the
2154           --color[=<when>] option.
2155
2156       color.diff.<slot>
2157           Use customized color for diff colorization.  <slot> specifies which
2158           part of the patch to use the specified color, and is one of context
2159           (context text - plain is a historical synonym), meta
2160           (metainformation), frag (hunk header), func (function in hunk
2161           header), old (removed lines), new (added lines), commit (commit
2162           headers), whitespace (highlighting whitespace errors), oldMoved
2163           (deleted lines), newMoved (added lines), oldMovedDimmed,
2164           oldMovedAlternative, oldMovedAlternativeDimmed, newMovedDimmed,
2165           newMovedAlternative newMovedAlternativeDimmed (See the <mode>
2166           setting of --color-moved in git-diff(1) for details),
2167           contextDimmed, oldDimmed, newDimmed, contextBold, oldBold, and
2168           newBold (see git-range-diff(1) for details).
2169
2170       color.decorate.<slot>
2171           Use customized color for git log --decorate output.  <slot> is one
2172           of branch, remoteBranch, tag, stash or HEAD for local branches,
2173           remote-tracking branches, tags, stash and HEAD, respectively and
2174           grafted for grafted commits.
2175
2176       color.grep
2177           When set to always, always highlight matches. When false (or
2178           never), never. When set to true or auto, use color only when the
2179           output is written to the terminal. If unset, then the value of
2180           color.ui is used (auto by default).
2181
2182       color.grep.<slot>
2183           Use customized color for grep colorization.  <slot> specifies which
2184           part of the line to use the specified color, and is one of
2185
2186           context
2187               non-matching text in context lines (when using -A, -B, or -C)
2188
2189           filename
2190               filename prefix (when not using -h)

2193               function name lines (when using -p)
2194
2195           lineNumber
2196               line number prefix (when using -n)
2197
2198           column
2199               column number prefix (when using --column)
2200
2201           match
2202               matching text (same as setting matchContext and matchSelected)
2203
2204           matchContext
2205               matching text in context lines
2206
2207           matchSelected
2208               matching text in selected lines. Also, used to customize the
2209               following git-log(1) subcommands: --grep, --author, and
2210               --committer.
2211
2212           selected
2213               non-matching text in selected lines. Also, used to customize
2214               the following git-log(1) subcommands: --grep, --author and
2215               --committer.
2216
2217           separator
2218               separators between fields on a line (:, -, and =) and between
2219               hunks (--)
2220
2221       color.interactive
2222           When set to always, always use colors for interactive prompts and
2223           displays (such as those used by "git-add --interactive" and
2224           "git-clean --interactive"). When false (or never), never. When set
2225           to true or auto, use colors only when the output is to the
2226           terminal. If unset, then the value of color.ui is used (auto by
2227           default).
2228
2229       color.interactive.<slot>
2230           Use customized color for git add --interactive and git clean
2231           --interactive output.  <slot> may be prompt, header, help or error,
2232           for four distinct types of normal output from interactive commands.
2233
2234       color.pager
2235           A boolean to specify whether auto color modes should colorize
2236           output going to the pager. Defaults to true; set this to false if
2237           your pager does not understand ANSI color codes.
2238
2239       color.push
2240           A boolean to enable/disable color in push errors. May be set to
2241           always, false (or never) or auto (or true), in which case colors
2242           are used only when the error output goes to a terminal. If unset,
2243           then the value of color.ui is used (auto by default).
2244
2245       color.push.error
2246           Use customized color for push errors.
2247
2248       color.remote
2249           If set, keywords at the start of the line are highlighted. The
2250           keywords are "error", "warning", "hint" and "success", and are
2251           matched case-insensitively. May be set to always, false (or never)
2252           or auto (or true). If unset, then the value of color.ui is used
2253           (auto by default).
2254
2255       color.remote.<slot>
2256           Use customized color for each remote keyword.  <slot> may be hint,
2257           warning, success or error which match the corresponding keyword.
2258
2259       color.showBranch
2260           A boolean to enable/disable color in the output of git-show-
2261           branch(1). May be set to always, false (or never) or auto (or
2262           true), in which case colors are used only when the output is to a
2263           terminal. If unset, then the value of color.ui is used (auto by
2264           default).
2265
2266       color.status
2267           A boolean to enable/disable color in the output of git-status(1).
2268           May be set to always, false (or never) or auto (or true), in which
2269           case colors are used only when the output is to a terminal. If
2270           unset, then the value of color.ui is used (auto by default).
2271
2272       color.status.<slot>
2273           Use customized color for status colorization.  <slot> is one of
2274           header (the header text of the status message), added or updated
2275           (files which are added but not committed), changed (files which are
2276           changed but not added in the index), untracked (files which are not
2277           tracked by Git), branch (the current branch), nobranch (the color
2278           the no branch warning is shown in, defaulting to red), localBranch
2279           or remoteBranch (the local and remote branch names, respectively,
2280           when branch and tracking information is displayed in the status
2281           short-format), or unmerged (files which have unmerged changes).
2282
2283       color.transport
2284           A boolean to enable/disable color when pushes are rejected. May be
2285           set to always, false (or never) or auto (or true), in which case
2286           colors are used only when the error output goes to a terminal. If
2287           unset, then the value of color.ui is used (auto by default).
2288
2289       color.transport.rejected
2290           Use customized color when a push was rejected.
2291
2292       color.ui
2293           This variable determines the default value for variables such as
2294           color.diff and color.grep that control the use of color per command
2295           family. Its scope will expand as more commands learn configuration
2296           to set a default for the --color option. Set it to false or never
2297           if you prefer Git commands not to use color unless enabled
2298           explicitly with some other configuration or the --color option. Set
2299           it to always if you want all output not intended for machine
2300           consumption to use color, to true or auto (this is the default
2301           since Git 1.8.4) if you want such output to use color when written
2302           to the terminal.
2303
2304       column.ui
2305           Specify whether supported commands should output in columns. This
2306           variable consists of a list of tokens separated by spaces or
2307           commas:
2308
2309           These options control when the feature should be enabled (defaults
2310           to never):
2311
2312           always
2313               always show in columns
2314
2315           never
2316               never show in columns
2317
2318           auto
2319               show in columns if the output is to the terminal
2320
2321           These options control layout (defaults to column). Setting any of
2322           these implies always if none of always, never, or auto are
2323           specified.
2324
2325           column
2326               fill columns before rows
2327
2328           row
2329               fill rows before columns
2330
2331           plain
2332               show in one column
2333
2334           Finally, these options can be combined with a layout option
2335           (defaults to nodense):
2336
2337           dense
2338               make unequal size columns to utilize more space
2339
2340           nodense
2341               make equal size columns
2342
2343       column.branch
2344           Specify whether to output branch listing in git branch in columns.
2345           See column.ui for details.
2346
2347       column.clean
2348           Specify the layout when listing items in git clean -i, which always
2349           shows files and directories in columns. See column.ui for details.
2350
2351       column.status
2352           Specify whether to output untracked files in git status in columns.
2353           See column.ui for details.
2354
2355       column.tag
2356           Specify whether to output tag listings in git tag in columns. See
2357           column.ui for details.
2358
2359       commit.cleanup
2360           This setting overrides the default of the --cleanup option in git
2361           commit. See git-commit(1) for details. Changing the default can be
2362           useful when you always want to keep lines that begin with the
2363           comment character # in your log message, in which case you would do
2364           git config commit.cleanup whitespace (note that you will have to
2365           remove the help lines that begin with # in the commit log template
2366           yourself, if you do this).
2367
2368       commit.gpgSign
2369           A boolean to specify whether all commits should be GPG signed. Use
2370           of this option when doing operations such as rebase can result in a
2371           large number of commits being signed. It may be convenient to use
2372           an agent to avoid typing your GPG passphrase several times.
2373
2374       commit.status
2375           A boolean to enable/disable inclusion of status information in the
2376           commit message template when using an editor to prepare the commit
2377           message. Defaults to true.
2378
2379       commit.template
2380           Specify the pathname of a file to use as the template for new
2381           commit messages.
2382
2383       commit.verbose
2384           A boolean or int to specify the level of verbosity with git commit.
2385           See git-commit(1).
2386
2387       commitGraph.generationVersion
2388           Specifies the type of generation number version to use when writing
2389           or reading the commit-graph file. If version 1 is specified, then
2390           the corrected commit dates will not be written or read. Defaults to
2391           2.
2392
2393       commitGraph.maxNewFilters
2394           Specifies the default value for the --max-new-filters option of git
2395           commit-graph write (c.f., git-commit-graph(1)).
2396
2397       commitGraph.readChangedPaths
2398           If true, then git will use the changed-path Bloom filters in the
2399           commit-graph file (if it exists, and they are present). Defaults to
2400           true. See git-commit-graph(1) for more information.
2401
2402       credential.helper
2403           Specify an external helper to be called when a username or password
2404           credential is needed; the helper may consult external storage to
2405           avoid prompting the user for the credentials. This is normally the
2406           name of a credential helper with possible arguments, but may also
2407           be an absolute path with arguments or, if preceded by !, shell
2408           commands.
2409
2410           Note that multiple helpers may be defined. See gitcredentials(7)
2411           for details and examples.
2412
2413       credential.useHttpPath
2414           When acquiring credentials, consider the "path" component of an
2415           http or https URL to be important. Defaults to false. See
2416           gitcredentials(7) for more information.
2417
2418       credential.username
2419           If no username is set for a network authentication, use this
2420           username by default. See credential.<context>.* below, and
2421           gitcredentials(7).
2422
2423       credential.<url>.*
2424           Any of the credential.* options above can be applied selectively to
2425           some credentials. For example,
2426           "credential.https://example.com.username" would set the default
2427           username only for https connections to example.com. See
2428           gitcredentials(7) for details on how URLs are matched.
2429
2430       credentialCache.ignoreSIGHUP
2431           Tell git-credential-cache—daemon to ignore SIGHUP, instead of
2432           quitting.
2433
2434       credentialStore.lockTimeoutMS
2435           The length of time, in milliseconds, for git-credential-store to
2436           retry when trying to lock the credentials file. A value of 0 means
2437           not to retry at all; -1 means to try indefinitely. Default is 1000
2438           (i.e., retry for 1s).
2439
2440       completion.commands
2441           This is only used by git-completion.bash to add or remove commands
2442           from the list of completed commands. Normally only porcelain
2443           commands and a few select others are completed. You can add more
2444           commands, separated by space, in this variable. Prefixing the
2445           command with - will remove it from the existing list.
2446
2447       diff.autoRefreshIndex
2448           When using git diff to compare with work tree files, do not
2449           consider stat-only changes as changed. Instead, silently run git
2450           update-index --refresh to update the cached stat information for
2451           paths whose contents in the work tree match the contents in the
2452           index. This option defaults to true. Note that this affects only
2453           git diff Porcelain, and not lower level diff commands such as git
2454           diff-files.
2455
2456       diff.dirstat
2457           A comma separated list of --dirstat parameters specifying the
2458           default behavior of the --dirstat option to git-diff(1) and
2459           friends. The defaults can be overridden on the command line (using
2460           --dirstat=<param1,param2,...>). The fallback defaults (when not
2461           changed by diff.dirstat) are changes,noncumulative,3. The following
2462           parameters are available:
2463
2464           changes
2465               Compute the dirstat numbers by counting the lines that have
2466               been removed from the source, or added to the destination. This
2467               ignores the amount of pure code movements within a file. In
2468               other words, rearranging lines in a file is not counted as much
2469               as other changes. This is the default behavior when no
2470               parameter is given.
2471
2472           lines
2473               Compute the dirstat numbers by doing the regular line-based
2474               diff analysis, and summing the removed/added line counts. (For
2475               binary files, count 64-byte chunks instead, since binary files
2476               have no natural concept of lines). This is a more expensive
2477               --dirstat behavior than the changes behavior, but it does count
2478               rearranged lines within a file as much as other changes. The
2479               resulting output is consistent with what you get from the other
2480               --*stat options.
2481
2482           files
2483               Compute the dirstat numbers by counting the number of files
2484               changed. Each changed file counts equally in the dirstat
2485               analysis. This is the computationally cheapest --dirstat
2486               behavior, since it does not have to look at the file contents
2487               at all.
2488
2489           cumulative
2490               Count changes in a child directory for the parent directory as
2491               well. Note that when using cumulative, the sum of the
2492               percentages reported may exceed 100%. The default
2493               (non-cumulative) behavior can be specified with the
2494               noncumulative parameter.
2495
2496           <limit>
2497               An integer parameter specifies a cut-off percent (3% by
2498               default). Directories contributing less than this percentage of
2499               the changes are not shown in the output.
2500
2501           Example: The following will count changed files, while ignoring
2502           directories with less than 10% of the total amount of changed
2503           files, and accumulating child directory counts in the parent
2504           directories: files,10,cumulative.
2505
2506       diff.statNameWidth
2507           Limit the width of the filename part in --stat output. If set,
2508           applies to all commands generating --stat output except
2509           format-patch.
2510
2511       diff.statGraphWidth
2512           Limit the width of the graph part in --stat output. If set, applies
2513           to all commands generating --stat output except format-patch.
2514
2515       diff.context
2516           Generate diffs with <n> lines of context instead of the default of
2517           3. This value is overridden by the -U option.
2518
2519       diff.interHunkContext
2520           Show the context between diff hunks, up to the specified number of
2521           lines, thereby fusing the hunks that are close to each other. This
2522           value serves as the default for the --inter-hunk-context command
2523           line option.
2524
2525       diff.external
2526           If this config variable is set, diff generation is not performed
2527           using the internal diff machinery, but using the given command. Can
2528           be overridden with the “GIT_EXTERNAL_DIFF” environment variable.
2529           The command is called with parameters as described under "git
2530           Diffs" in git(1). Note: if you want to use an external diff program
2531           only on a subset of your files, you might want to use
2532           gitattributes(5) instead.
2533
2534       diff.ignoreSubmodules
2535           Sets the default value of --ignore-submodules. Note that this
2536           affects only git diff Porcelain, and not lower level diff commands
2537           such as git diff-files.  git checkout and git switch also honor
2538           this setting when reporting uncommitted changes. Setting it to all
2539           disables the submodule summary normally shown by git commit and git
2540           status when status.submoduleSummary is set unless it is overridden
2541           by using the --ignore-submodules command-line option. The git
2542           submodule commands are not affected by this setting. By default
2543           this is set to untracked so that any untracked submodules are
2544           ignored.
2545
2546       diff.mnemonicPrefix
2547           If set, git diff uses a prefix pair that is different from the
2548           standard "a/" and "b/" depending on what is being compared. When
2549           this configuration is in effect, reverse diff output also swaps the
2550           order of the prefixes:
2551
2552           git diff
2553               compares the (i)ndex and the (w)ork tree;
2554
2555           git diff HEAD
2556               compares a (c)ommit and the (w)ork tree;
2557
2558           git diff --cached
2559               compares a (c)ommit and the (i)ndex;
2560
2561           git diff HEAD:file1 file2
2562               compares an (o)bject and a (w)ork tree entity;
2563
2564           git diff --no-index a b
2565               compares two non-git things (1) and (2).
2566
2567       diff.noprefix
2568           If set, git diff does not show any source or destination prefix.
2569
2570       diff.relative
2571           If set to true, git diff does not show changes outside of the
2572           directory and show pathnames relative to the current directory.
2573
2574       diff.orderFile
2575           File indicating how to order files within a diff. See the -O option
2576           to git-diff(1) for details. If diff.orderFile is a relative
2577           pathname, it is treated as relative to the top of the working tree.
2578
2579       diff.renameLimit
2580           The number of files to consider in the exhaustive portion of
2581           copy/rename detection; equivalent to the git diff option -l. If not
2582           set, the default value is currently 1000. This setting has no
2583           effect if rename detection is turned off.
2584
2585       diff.renames
2586           Whether and how Git detects renames. If set to "false", rename
2587           detection is disabled. If set to "true", basic rename detection is
2588           enabled. If set to "copies" or "copy", Git will detect copies, as
2589           well. Defaults to true. Note that this affects only git diff
2590           Porcelain like git-diff(1) and git-log(1), and not lower level
2591           commands such as git-diff-files(1).
2592
2593       diff.suppressBlankEmpty
2594           A boolean to inhibit the standard behavior of printing a space
2595           before each empty output line. Defaults to false.
2596
2597       diff.submodule
2598           Specify the format in which differences in submodules are shown.
2599           The "short" format just shows the names of the commits at the
2600           beginning and end of the range. The "log" format lists the commits
2601           in the range like git-submodule(1) summary does. The "diff" format
2602           shows an inline diff of the changed contents of the submodule.
2603           Defaults to "short".
2604
2605       diff.wordRegex
2606           A POSIX Extended Regular Expression used to determine what is a
2607           "word" when performing word-by-word difference calculations.
2608           Character sequences that match the regular expression are "words",
2609           all other characters are ignorable whitespace.
2610
2611       diff.<driver>.command
2612           The custom diff driver command. See gitattributes(5) for details.
2613
2614       diff.<driver>.xfuncname
2615           The regular expression that the diff driver should use to recognize
2616           the hunk header. A built-in pattern may also be used. See
2617           gitattributes(5) for details.
2618
2619       diff.<driver>.binary
2620           Set this option to true to make the diff driver treat files as
2621           binary. See gitattributes(5) for details.
2622
2623       diff.<driver>.textconv
2624           The command that the diff driver should call to generate the
2625           text-converted version of a file. The result of the conversion is
2626           used to generate a human-readable diff. See gitattributes(5) for
2627           details.
2628
2629       diff.<driver>.wordRegex
2630           The regular expression that the diff driver should use to split
2631           words in a line. See gitattributes(5) for details.
2632
2633       diff.<driver>.cachetextconv
2634           Set this option to true to make the diff driver cache the text
2635           conversion outputs. See gitattributes(5) for details.

2710           Set this option to false to disable the default heuristics that
2711           shift diff hunk boundaries to make patches easier to read.
2712
2713       diff.algorithm
2714           Choose a diff algorithm. The variants are as follows:
2715
2716           default, myers
2717               The basic greedy diff algorithm. Currently, this is the
2718               default.
2719
2720           minimal
2721               Spend extra time to make sure the smallest possible diff is
2722               produced.
2723
2724           patience
2725               Use "patience diff" algorithm when generating patches.
2726
2727           histogram
2728               This algorithm extends the patience algorithm to "support
2729               low-occurrence common elements".
2730
2731       diff.wsErrorHighlight
2732           Highlight whitespace errors in the context, old or new lines of the
2733           diff. Multiple values are separated by comma, none resets previous
2734           values, default reset the list to new and all is a shorthand for
2735           old,new,context. The whitespace errors are colored with
2736           color.diff.whitespace. The command line option
2737           --ws-error-highlight=<kind> overrides this setting.
2738
2739       diff.colorMoved
2740           If set to either a valid <mode> or a true value, moved lines in a
2741           diff are colored differently, for details of valid modes see
2742           --color-moved in git-diff(1). If simply set to true the default
2743           color mode will be used. When set to false, moved lines are not
2744           colored.
2745
2746       diff.colorMovedWS
2747           When moved lines are colored using e.g. the diff.colorMoved
2748           setting, this option controls the <mode> how spaces are treated for
2749           details of valid modes see --color-moved-ws in git-diff(1).
2750
2751       diff.tool
2752           Controls which diff tool is used by git-difftool(1). This variable
2753           overrides the value configured in merge.tool. The list below shows
2754           the valid built-in values. Any other value is treated as a custom
2755           diff tool and requires that a corresponding difftool.<tool>.cmd
2756           variable is defined.
2757
2758       diff.guitool
2759           Controls which diff tool is used by git-difftool(1) when the
2760           -g/--gui flag is specified. This variable overrides the value
2761           configured in merge.guitool. The list below shows the valid
2762           built-in values. Any other value is treated as a custom diff tool
2763           and requires that a corresponding difftool.<guitool>.cmd variable
2764           is defined.
2765
2766       difftool.<tool>.cmd
2767           Specify the command to invoke the specified diff tool. The
2768           specified command is evaluated in shell with the following
2769           variables available: LOCAL is set to the name of the temporary file
2770           containing the contents of the diff pre-image and REMOTE is set to
2771           the name of the temporary file containing the contents of the diff
2772           post-image.
2773
2774           See the --tool=<tool> option in git-difftool(1) for more details.
2775
2776       difftool.<tool>.path
2777           Override the path for the given tool. This is useful in case your
2778           tool is not in the PATH.
2779
2780       difftool.trustExitCode
2781           Exit difftool if the invoked diff tool returns a non-zero exit
2782           status.
2783
2784           See the --trust-exit-code option in git-difftool(1) for more
2785           details.
2786
2787       difftool.prompt
2788           Prompt before each invocation of the diff tool.
2789
2790       difftool.guiDefault
2791           Set true to use the diff.guitool by default (equivalent to
2792           specifying the --gui argument), or auto to select diff.guitool or
2793           diff.tool depending on the presence of a DISPLAY environment
2794           variable value. The default is false, where the --gui argument must
2795           be provided explicitly for the diff.guitool to be used.
2796
2797       extensions.objectFormat
2798           Specify the hash algorithm to use. The acceptable values are sha1
2799           and sha256. If not specified, sha1 is assumed. It is an error to
2800           specify this key unless core.repositoryFormatVersion is 1.
2801
2802           Note that this setting should only be set by git-init(1) or git-
2803           clone(1). Trying to change it after initialization will not work
2804           and will produce hard-to-diagnose issues.
2805
2806       extensions.worktreeConfig
2807           If enabled, then worktrees will load config settings from the
2808           $GIT_DIR/config.worktree file in addition to the
2809           $GIT_COMMON_DIR/config file. Note that $GIT_COMMON_DIR and $GIT_DIR
2810           are the same for the main working tree, while other working trees
2811           have $GIT_DIR equal to $GIT_COMMON_DIR/worktrees/<id>/. The
2812           settings in the config.worktree file will override settings from
2813           any other config files.
2814
2815           When enabling extensions.worktreeConfig, you must be careful to
2816           move certain values from the common config file to the main working
2817           tree’s config.worktree file, if present:
2818
2819core.worktree must be moved from $GIT_COMMON_DIR/config to
2820               $GIT_COMMON_DIR/config.worktree.
2821
2822           •   If core.bare is true, then it must be moved from
2823               $GIT_COMMON_DIR/config to $GIT_COMMON_DIR/config.worktree.
2824
2825               It may also be beneficial to adjust the locations of
2826               core.sparseCheckout and core.sparseCheckoutCone depending on
2827               your desire for customizable sparse-checkout settings for each
2828               worktree. By default, the git sparse-checkout builtin enables
2829               extensions.worktreeConfig, assigns these config values on a
2830               per-worktree basis, and uses the $GIT_DIR/info/sparse-checkout
2831               file to specify the sparsity for each worktree independently.
2832               See git-sparse-checkout(1) for more details.
2833
2834               For historical reasons, extensions.worktreeConfig is respected
2835               regardless of the core.repositoryFormatVersion setting.
2836
2837       fastimport.unpackLimit
2838           If the number of objects imported by git-fast-import(1) is below
2839           this limit, then the objects will be unpacked into loose object
2840           files. However, if the number of imported objects equals or exceeds
2841           this limit, then the pack will be stored as a pack. Storing the
2842           pack from a fast-import can make the import operation complete
2843           faster, especially on slow filesystems. If not set, the value of
2844           transfer.unpackLimit is used instead.
2845
2846       feature.*
2847           The config settings that start with feature.  modify the defaults
2848           of a group of other config settings. These groups are created by
2849           the Git developer community as recommended defaults and are subject
2850           to change. In particular, new config options may be added with
2851           different defaults.
2852
2853       feature.experimental
2854           Enable config options that are new to Git, and are being considered
2855           for future defaults. Config settings included here may be added or
2856           removed with each release, including minor version updates. These
2857           settings may have unintended interactions since they are so new.
2858           Please enable this setting if you are interested in providing
2859           feedback on experimental features. The new default values are:
2860
2861fetch.negotiationAlgorithm=skipping may improve fetch
2862               negotiation times by skipping more commits at a time, reducing
2863               the number of round trips.
2864
2865pack.useBitmapBoundaryTraversal=true may improve bitmap
2866               traversal times by walking fewer objects.
2867
2868       feature.manyFiles
2869           Enable config options that optimize for repos with many files in
2870           the working directory. With many files, commands such as git status
2871           and git checkout may be slow and these new defaults improve
2872           performance:
2873
2874index.skipHash=true speeds up index writes by not computing a
2875               trailing checksum. Note that this will cause Git versions
2876               earlier than 2.13.0 to refuse to parse the index and Git
2877               versions earlier than 2.40.0 will report a corrupted index
2878               during git fsck.
2879
2880index.version=4 enables path-prefix compression in the index.
2881
2882core.untrackedCache=true enables the untracked cache. This
2883               setting assumes that mtime is working on your machine.
2884
2885       fetch.recurseSubmodules
2886           This option controls whether git fetch (and the underlying fetch in
2887           git pull) will recursively fetch into populated submodules. This
2888           option can be set either to a boolean value or to on-demand.
2889           Setting it to a boolean changes the behavior of fetch and pull to
2890           recurse unconditionally into submodules when set to true or to not
2891           recurse at all when set to false. When set to on-demand, fetch and
2892           pull will only recurse into a populated submodule when its
2893           superproject retrieves a commit that updates the submodule’s
2894           reference. Defaults to on-demand, or to the value of
2895           submodule.recurse if set.
2896
2897       fetch.fsckObjects
2898           If it is set to true, git-fetch-pack will check all fetched
2899           objects. See transfer.fsckObjects for what’s checked. Defaults to
2900           false. If not set, the value of transfer.fsckObjects is used
2901           instead.
2902
2903       fetch.fsck.<msg-id>
2904           Acts like fsck.<msg-id>, but is used by git-fetch-pack(1) instead
2905           of git-fsck(1). See the fsck.<msg-id> documentation for details.
2906
2907       fetch.fsck.skipList
2908           Acts like fsck.skipList, but is used by git-fetch-pack(1) instead
2909           of git-fsck(1). See the fsck.skipList documentation for details.
2910
2911       fetch.unpackLimit
2912           If the number of objects fetched over the Git native transfer is
2913           below this limit, then the objects will be unpacked into loose
2914           object files. However if the number of received objects equals or
2915           exceeds this limit then the received pack will be stored as a pack,
2916           after adding any missing delta bases. Storing the pack from a push
2917           can make the push operation complete faster, especially on slow
2918           filesystems. If not set, the value of transfer.unpackLimit is used
2919           instead.
2920
2921       fetch.prune
2922           If true, fetch will automatically behave as if the --prune option
2923           was given on the command line. See also remote.<name>.prune and the
2924           PRUNING section of git-fetch(1).
2925
2926       fetch.pruneTags
2927           If true, fetch will automatically behave as if the
2928           refs/tags/*:refs/tags/* refspec was provided when pruning, if not
2929           set already. This allows for setting both this option and
2930           fetch.prune to maintain a 1=1 mapping to upstream refs. See also
2931           remote.<name>.pruneTags and the PRUNING section of git-fetch(1).
2932
2933       fetch.output
2934           Control how ref update status is printed. Valid values are full and
2935           compact. Default value is full. See the OUTPUT section in git-
2936           fetch(1) for details.
2937
2938       fetch.negotiationAlgorithm
2939           Control how information about the commits in the local repository
2940           is sent when negotiating the contents of the packfile to be sent by
2941           the server. Set to "consecutive" to use an algorithm that walks
2942           over consecutive commits checking each one. Set to "skipping" to
2943           use an algorithm that skips commits in an effort to converge
2944           faster, but may result in a larger-than-necessary packfile; or set
2945           to "noop" to not send any information at all, which will almost
2946           certainly result in a larger-than-necessary packfile, but will skip
2947           the negotiation step. Set to "default" to override settings made
2948           previously and use the default behaviour. The default is normally
2949           "consecutive", but if feature.experimental is true, then the
2950           default is "skipping". Unknown values will cause git fetch to error
2951           out.
2952
2953           See also the --negotiate-only and --negotiation-tip options to git-
2954           fetch(1).
2955
2956       fetch.showForcedUpdates
2957           Set to false to enable --no-show-forced-updates in git-fetch(1) and
2958           git-pull(1) commands. Defaults to true.
2959
2960       fetch.parallel
2961           Specifies the maximal number of fetch operations to be run in
2962           parallel at a time (submodules, or remotes when the --multiple
2963           option of git-fetch(1) is in effect).
2964
2965           A value of 0 will give some reasonable default. If unset, it
2966           defaults to 1.
2967
2968           For submodules, this setting can be overridden using the
2969           submodule.fetchJobs config setting.
2970
2971       fetch.writeCommitGraph
2972           Set to true to write a commit-graph after every git fetch command
2973           that downloads a pack-file from a remote. Using the --split option,
2974           most executions will create a very small commit-graph file on top
2975           of the existing commit-graph file(s). Occasionally, these files
2976           will merge and the write may take longer. Having an updated
2977           commit-graph file helps performance of many Git commands, including
2978           git merge-base, git push -f, and git log --graph. Defaults to
2979           false.
2980
2981       fetch.bundleURI
2982           This value stores a URI for downloading Git object data from a
2983           bundle URI before performing an incremental fetch from the origin
2984           Git server. This is similar to how the --bundle-uri option behaves
2985           in git-clone(1).  git clone --bundle-uri will set the
2986           fetch.bundleURI value if the supplied bundle URI contains a bundle
2987           list that is organized for incremental fetches.
2988
2989           If you modify this value and your repository has a
2990           fetch.bundleCreationToken value, then remove that
2991           fetch.bundleCreationToken value before fetching from the new bundle
2992           URI.
2993
2994       fetch.bundleCreationToken
2995           When using fetch.bundleURI to fetch incrementally from a bundle
2996           list that uses the "creationToken" heuristic, this config value
2997           stores the maximum creationToken value of the downloaded bundles.
2998           This value is used to prevent downloading bundles in the future if
2999           the advertised creationToken is not strictly larger than this
3000           value.
3001
3002           The creation token values are chosen by the provider serving the
3003           specific bundle URI. If you modify the URI at fetch.bundleURI, then
3004           be sure to remove the value for the fetch.bundleCreationToken value
3005           before fetching.
3006
3007       format.attach
3008           Enable multipart/mixed attachments as the default for format-patch.
3009           The value can also be a double quoted string which will enable
3010           attachments as the default and set the value as the boundary. See
3011           the --attach option in git-format-patch(1). To countermand an
3012           earlier value, set it to an empty string.
3013
3014       format.from
3015           Provides the default value for the --from option to format-patch.
3016           Accepts a boolean value, or a name and email address. If false,
3017           format-patch defaults to --no-from, using commit authors directly
3018           in the "From:" field of patch mails. If true, format-patch defaults
3019           to --from, using your committer identity in the "From:" field of
3020           patch mails and including a "From:" field in the body of the patch
3021           mail if different. If set to a non-boolean value, format-patch uses
3022           that value instead of your committer identity. Defaults to false.
3023
3024       format.forceInBodyFrom
3025           Provides the default value for the --[no-]force-in-body-from option
3026           to format-patch. Defaults to false.
3027
3028       format.numbered
3029           A boolean which can enable or disable sequence numbers in patch
3030           subjects. It defaults to "auto" which enables it only if there is
3031           more than one patch. It can be enabled or disabled for all messages
3032           by setting it to "true" or "false". See --numbered option in git-
3033           format-patch(1).
3034
3035       format.headers
3036           Additional email headers to include in a patch to be submitted by
3037           mail. See git-format-patch(1).
3038
3039       format.to, format.cc
3040           Additional recipients to include in a patch to be submitted by
3041           mail. See the --to and --cc options in git-format-patch(1).
3042
3043       format.subjectPrefix
3044           The default for format-patch is to output files with the [PATCH]
3045           subject prefix. Use this variable to change that prefix.
3046
3047       format.coverFromDescription
3048           The default mode for format-patch to determine which parts of the
3049           cover letter will be populated using the branch’s description. See
3050           the --cover-from-description option in git-format-patch(1).
3051
3052       format.signature
3053           The default for format-patch is to output a signature containing
3054           the Git version number. Use this variable to change that default.
3055           Set this variable to the empty string ("") to suppress signature
3056           generation.
3057
3058       format.signatureFile
3059           Works just like format.signature except the contents of the file
3060           specified by this variable will be used as the signature.
3061
3062       format.suffix
3063           The default for format-patch is to output files with the suffix
3064           .patch. Use this variable to change that suffix (make sure to
3065           include the dot if you want it).
3066
3067       format.encodeEmailHeaders
3068           Encode email headers that have non-ASCII characters with
3069           "Q-encoding" (described in RFC 2047) for email transmission.
3070           Defaults to true.
3071
3072       format.pretty
3073           The default pretty format for log/show/whatchanged command. See
3074           git-log(1), git-show(1), git-whatchanged(1).
3075
3076       format.thread
3077           The default threading style for git format-patch. Can be a boolean
3078           value, or shallow or deep.  shallow threading makes every mail a
3079           reply to the head of the series, where the head is chosen from the
3080           cover letter, the --in-reply-to, and the first patch mail, in this
3081           order.  deep threading makes every mail a reply to the previous
3082           one. A true boolean value is the same as shallow, and a false value
3083           disables threading.
3084
3085       format.signOff
3086           A boolean value which lets you enable the -s/--signoff option of
3087           format-patch by default.  Note: Adding the Signed-off-by trailer to
3088           a patch should be a conscious act and means that you certify you
3089           have the rights to submit this work under the same open source
3090           license. Please see the SubmittingPatches document for further
3091           discussion.
3092
3093       format.coverLetter
3094           A boolean that controls whether to generate a cover-letter when
3095           format-patch is invoked, but in addition can be set to "auto", to
3096           generate a cover-letter only when there’s more than one patch.
3097           Default is false.
3098
3099       format.outputDirectory
3100           Set a custom directory to store the resulting files instead of the
3101           current working directory. All directory components will be
3102           created.
3103
3104       format.filenameMaxLength
3105           The maximum length of the output filenames generated by the
3106           format-patch command; defaults to 64. Can be overridden by the
3107           --filename-max-length=<n> command line option.
3108
3109       format.useAutoBase
3110           A boolean value which lets you enable the --base=auto option of
3111           format-patch by default. Can also be set to "whenAble" to allow
3112           enabling --base=auto if a suitable base is available, but to skip
3113           adding base info otherwise without the format dying.
3114
3115       format.notes
3116           Provides the default value for the --notes option to format-patch.
3117           Accepts a boolean value, or a ref which specifies where to get
3118           notes. If false, format-patch defaults to --no-notes. If true,
3119           format-patch defaults to --notes. If set to a non-boolean value,
3120           format-patch defaults to --notes=<ref>, where ref is the
3121           non-boolean value. Defaults to false.
3122
3123           If one wishes to use the ref ref/notes/true, please use that
3124           literal instead.
3125
3126           This configuration can be specified multiple times in order to
3127           allow multiple notes refs to be included. In that case, it will
3128           behave similarly to multiple --[no-]notes[=] options passed in.
3129           That is, a value of true will show the default notes, a value of
3130           <ref> will also show notes from that notes ref and a value of false
3131           will negate previous configurations and not show notes.
3132
3133           For example,
3134
3135               [format]
3136                       notes = true
3137                       notes = foo
3138                       notes = false
3139                       notes = bar
3140
3141           will only show notes from refs/notes/bar.
3142
3143       format.mboxrd
3144           A boolean value which enables the robust "mboxrd" format when
3145           --stdout is in use to escape "^>+From " lines.
3146
3147       format.noprefix
3148           If set, do not show any source or destination prefix in patches.
3149           This is equivalent to the diff.noprefix option used by git diff
3150           (but which is not respected by format-patch). Note that by setting
3151           this, the receiver of any patches you generate will have to apply
3152           them using the -p0 option.
3153
3154       filter.<driver>.clean
3155           The command which is used to convert the content of a worktree file
3156           to a blob upon checkin. See gitattributes(5) for details.
3157
3158       filter.<driver>.smudge
3159           The command which is used to convert the content of a blob object
3160           to a worktree file upon checkout. See gitattributes(5) for details.

3162       fsck.<msg-id>
3163           During fsck git may find issues with legacy data which wouldn’t be
3164           generated by current versions of git, and which wouldn’t be sent
3165           over the wire if transfer.fsckObjects was set. This feature is
3166           intended to support working with legacy repositories containing
3167           such data.
3168
3169           Setting fsck.<msg-id> will be picked up by git-fsck(1), but to
3170           accept pushes of such data set receive.fsck.<msg-id> instead, or to
3171           clone or fetch it set fetch.fsck.<msg-id>.
3172
3173           The rest of the documentation discusses fsck.*  for brevity, but
3174           the same applies for the corresponding receive.fsck.*  and
3175           fetch.fsck.*. variables.
3176
3177           Unlike variables like color.ui and core.editor, the
3178           receive.fsck.<msg-id> and fetch.fsck.<msg-id> variables will not
3179           fall back on the fsck.<msg-id> configuration if they aren’t set. To
3180           uniformly configure the same fsck settings in different
3181           circumstances, all three of them must be set to the same values.
3182
3183           When fsck.<msg-id> is set, errors can be switched to warnings and
3184           vice versa by configuring the fsck.<msg-id> setting where the
3185           <msg-id> is the fsck message ID and the value is one of error, warn
3186           or ignore. For convenience, fsck prefixes the error/warning with
3187           the message ID, e.g. "missingEmail: invalid author/committer line -
3188           missing email" means that setting fsck.missingEmail = ignore will
3189           hide that issue.
3190
3191           In general, it is better to enumerate existing objects with
3192           problems with fsck.skipList, instead of listing the kind of
3193           breakages these problematic objects share to be ignored, as doing
3194           the latter will allow new instances of the same breakages go
3195           unnoticed.
3196
3197           Setting an unknown fsck.<msg-id> value will cause fsck to die, but
3198           doing the same for receive.fsck.<msg-id> and fetch.fsck.<msg-id>
3199           will only cause git to warn.
3200
3201           See the Fsck Messages section of git-fsck(1) for supported values
3202           of <msg-id>.
3203
3204       fsck.skipList
3205           The path to a list of object names (i.e. one unabbreviated SHA-1
3206           per line) that are known to be broken in a non-fatal way and should
3207           be ignored. On versions of Git 2.20 and later, comments (#), empty
3208           lines, and any leading and trailing whitespace are ignored.
3209           Everything but a SHA-1 per line will error out on older versions.
3210
3211           This feature is useful when an established project should be
3212           accepted despite early commits containing errors that can be safely
3213           ignored, such as invalid committer email addresses. Note: corrupt
3214           objects cannot be skipped with this setting.
3215
3216           Like fsck.<msg-id> this variable has corresponding
3217           receive.fsck.skipList and fetch.fsck.skipList variants.
3218
3219           Unlike variables like color.ui and core.editor the
3220           receive.fsck.skipList and fetch.fsck.skipList variables will not
3221           fall back on the fsck.skipList configuration if they aren’t set. To
3222           uniformly configure the same fsck settings in different
3223           circumstances, all three of them must be set to the same values.
3224
3225           Older versions of Git (before 2.20) documented that the object
3226           names list should be sorted. This was never a requirement; the
3227           object names could appear in any order, but when reading the list
3228           we tracked whether the list was sorted for the purposes of an
3229           internal binary search implementation, which could save itself some
3230           work with an already sorted list. Unless you had a humongous list
3231           there was no reason to go out of your way to pre-sort the list.
3232           After Git version 2.20 a hash implementation is used instead, so
3233           there’s now no reason to pre-sort the list.
3234
3235       fsmonitor.allowRemote
3236           By default, the fsmonitor daemon refuses to work with
3237           network-mounted repositories. Setting fsmonitor.allowRemote to true
3238           overrides this behavior. Only respected when core.fsmonitor is set
3239           to true.
3240
3241       fsmonitor.socketDir
3242           This Mac OS-specific option, if set, specifies the directory in
3243           which to create the Unix domain socket used for communication
3244           between the fsmonitor daemon and various Git commands. The
3245           directory must reside on a native Mac OS filesystem. Only respected
3246           when core.fsmonitor is set to true.
3247
3248       gc.aggressiveDepth
3249           The depth parameter used in the delta compression algorithm used by
3250           git gc --aggressive. This defaults to 50, which is the default for
3251           the --depth option when --aggressive isn’t in use.
3252
3253           See the documentation for the --depth option in git-repack(1) for
3254           more details.
3255
3256       gc.aggressiveWindow
3257           The window size parameter used in the delta compression algorithm
3258           used by git gc --aggressive. This defaults to 250, which is a much
3259           more aggressive window size than the default --window of 10.
3260
3261           See the documentation for the --window option in git-repack(1) for
3262           more details.
3263
3264       gc.auto
3265           When there are approximately more than this many loose objects in
3266           the repository, git gc --auto will pack them. Some Porcelain
3267           commands use this command to perform a light-weight garbage
3268           collection from time to time. The default value is 6700.
3269
3270           Setting this to 0 disables not only automatic packing based on the
3271           number of loose objects, but also any other heuristic git gc --auto
3272           will otherwise use to determine if there’s work to do, such as
3273           gc.autoPackLimit.
3274
3275       gc.autoPackLimit
3276           When there are more than this many packs that are not marked with
3277           *.keep file in the repository, git gc --auto consolidates them into
3278           one larger pack. The default value is 50. Setting this to 0
3279           disables it. Setting gc.auto to 0 will also disable this.
3280
3281           See the gc.bigPackThreshold configuration variable below. When in
3282           use, it’ll affect how the auto pack limit works.
3283
3284       gc.autoDetach
3285           Make git gc --auto return immediately and run in the background if
3286           the system supports it. Default is true.
3287
3288       gc.bigPackThreshold
3289           If non-zero, all non-cruft packs larger than this limit are kept
3290           when git gc is run. This is very similar to --keep-largest-pack
3291           except that all non-cruft packs that meet the threshold are kept,
3292           not just the largest pack. Defaults to zero. Common unit suffixes
3293           of k, m, or g are supported.
3294
3295           Note that if the number of kept packs is more than
3296           gc.autoPackLimit, this configuration variable is ignored, all packs
3297           except the base pack will be repacked. After this the number of
3298           packs should go below gc.autoPackLimit and gc.bigPackThreshold
3299           should be respected again.
3300
3301           If the amount of memory estimated for git repack to run smoothly is
3302           not available and gc.bigPackThreshold is not set, the largest pack
3303           will also be excluded (this is the equivalent of running git gc
3304           with --keep-largest-pack).
3305
3306       gc.writeCommitGraph
3307           If true, then gc will rewrite the commit-graph file when git-gc(1)
3308           is run. When using git gc --auto the commit-graph will be updated
3309           if housekeeping is required. Default is true. See git-commit-
3310           graph(1) for details.
3311
3312       gc.logExpiry
3313           If the file gc.log exists, then git gc --auto will print its
3314           content and exit with status zero instead of running unless that
3315           file is more than gc.logExpiry old. Default is "1.day". See
3316           gc.pruneExpire for more ways to specify its value.
3317
3318       gc.packRefs
3319           Running git pack-refs in a repository renders it unclonable by Git
3320           versions prior to 1.5.1.2 over dumb transports such as HTTP. This
3321           variable determines whether git gc runs git pack-refs. This can be
3322           set to notbare to enable it within all non-bare repos or it can be
3323           set to a boolean value. The default is true.
3324
3325       gc.cruftPacks
3326           Store unreachable objects in a cruft pack (see git-repack(1))
3327           instead of as loose objects. The default is true.
3328
3329       gc.maxCruftSize
3330           Limit the size of new cruft packs when repacking. When specified in
3331           addition to --max-cruft-size, the command line option takes
3332           priority. See the --max-cruft-size option of git-repack(1).
3333
3334       gc.pruneExpire
3335           When git gc is run, it will call prune --expire 2.weeks.ago (and
3336           repack --cruft --cruft-expiration 2.weeks.ago if using cruft packs
3337           via gc.cruftPacks or --cruft). Override the grace period with this
3338           config variable. The value "now" may be used to disable this grace
3339           period and always prune unreachable objects immediately, or "never"
3340           may be used to suppress pruning. This feature helps prevent
3341           corruption when git gc runs concurrently with another process
3342           writing to the repository; see the "NOTES" section of git-gc(1).
3343
3344       gc.worktreePruneExpire
3345           When git gc is run, it calls git worktree prune --expire
3346           3.months.ago. This config variable can be used to set a different
3347           grace period. The value "now" may be used to disable the grace
3348           period and prune $GIT_DIR/worktrees immediately, or "never" may be
3349           used to suppress pruning.
3350
3351       gc.reflogExpire, gc.<pattern>.reflogExpire
3352           git reflog expire removes reflog entries older than this time;
3353           defaults to 90 days. The value "now" expires all entries
3354           immediately, and "never" suppresses expiration altogether. With
3355           "<pattern>" (e.g. "refs/stash") in the middle the setting applies
3356           only to the refs that match the <pattern>.
3357
3358       gc.reflogExpireUnreachable, gc.<pattern>.reflogExpireUnreachable
3359           git reflog expire removes reflog entries older than this time and
3360           are not reachable from the current tip; defaults to 30 days. The
3361           value "now" expires all entries immediately, and "never" suppresses
3362           expiration altogether. With "<pattern>" (e.g. "refs/stash") in the
3363           middle, the setting applies only to the refs that match the
3364           <pattern>.
3365
3366           These types of entries are generally created as a result of using
3367           git commit --amend or git rebase and are the commits prior to the
3368           amend or rebase occurring. Since these changes are not part of the
3369           current project most users will want to expire them sooner, which
3370           is why the default is more aggressive than gc.reflogExpire.
3371
3372       gc.recentObjectsHook
3373           When considering whether or not to remove an object (either when
3374           generating a cruft pack or storing unreachable objects as loose),
3375           use the shell to execute the specified command(s). Interpret their
3376           output as object IDs which Git will consider as "recent",
3377           regardless of their age. By treating their mtimes as "now", any
3378           objects (and their descendants) mentioned in the output will be
3379           kept regardless of their true age.
3380
3381           Output must contain exactly one hex object ID per line, and nothing
3382           else. Objects which cannot be found in the repository are ignored.
3383           Multiple hooks are supported, but all must exit successfully, else
3384           the operation (either generating a cruft pack or unpacking
3385           unreachable objects) will be halted.
3386
3387       gc.repackFilter
3388           When repacking, use the specified filter to move certain objects
3389           into a separate packfile. See the --filter=<filter-spec> option of
3390           git-repack(1).
3391
3392       gc.repackFilterTo
3393           When repacking and using a filter, see gc.repackFilter, the
3394           specified location will be used to create the packfile containing
3395           the filtered out objects.  WARNING: The specified location should
3396           be accessible, using for example the Git alternates mechanism,
3397           otherwise the repo could be considered corrupt by Git as it migh
3398           not be able to access the objects in that packfile. See the
3399           --filter-to=<dir> option of git-repack(1) and the
3400           objects/info/alternates section of gitrepository-layout(5).
3401
3402       gc.rerereResolved
3403           Records of conflicted merge you resolved earlier are kept for this
3404           many days when git rerere gc is run. You can also use more
3405           human-readable "1.month.ago", etc. The default is 60 days. See git-
3406           rerere(1).
3407
3408       gc.rerereUnresolved
3409           Records of conflicted merge you have not resolved are kept for this
3410           many days when git rerere gc is run. You can also use more
3411           human-readable "1.month.ago", etc. The default is 15 days. See git-
3412           rerere(1).
3413
3414       gitcvs.commitMsgAnnotation
3415           Append this string to each commit message. Set to empty string to
3416           disable this feature. Defaults to "via git-CVS emulator".
3417
3418       gitcvs.enabled
3419           Whether the CVS server interface is enabled for this repository.
3420           See git-cvsserver(1).
3421
3422       gitcvs.logFile
3423           Path to a log file where the CVS server interface well... logs
3424           various stuff. See git-cvsserver(1).
3425
3426       gitcvs.usecrlfattr
3427           If true, the server will look up the end-of-line conversion
3428           attributes for files to determine the -k modes to use. If the
3429           attributes force Git to treat a file as text, the -k mode will be
3430           left blank so CVS clients will treat it as text. If they suppress
3431           text conversion, the file will be set with -kb mode, which
3432           suppresses any newline munging the client might otherwise do. If
3433           the attributes do not allow the file type to be determined, then
3434           gitcvs.allBinary is used. See gitattributes(5).
3435
3436       gitcvs.allBinary
3437           This is used if gitcvs.usecrlfattr does not resolve the correct -kb
3438           mode to use. If true, all unresolved files are sent to the client
3439           in mode -kb. This causes the client to treat them as binary files,
3440           which suppresses any newline munging it otherwise might do.
3441           Alternatively, if it is set to "guess", then the contents of the
3442           file are examined to decide if it is binary, similar to
3443           core.autocrlf.
3444
3445       gitcvs.dbName
3446           Database used by git-cvsserver to cache revision information
3447           derived from the Git repository. The exact meaning depends on the
3448           used database driver, for SQLite (which is the default driver) this
3449           is a filename. Supports variable substitution (see git-cvsserver(1)
3450           for details). May not contain semicolons (;). Default:
3451           %Ggitcvs.%m.sqlite
3452
3453       gitcvs.dbDriver
3454           Used Perl DBI driver. You can specify any available driver for this
3455           here, but it might not work. git-cvsserver is tested with
3456           DBD::SQLite, reported to work with DBD::Pg, and reported not to
3457           work with DBD::mysql. Experimental feature. May not contain double
3458           colons (:). Default: SQLite. See git-cvsserver(1).
3459
3460       gitcvs.dbUser, gitcvs.dbPass
3461           Database user and password. Only useful if setting gitcvs.dbDriver,
3462           since SQLite has no concept of database users and/or passwords.
3463           gitcvs.dbUser supports variable substitution (see git-cvsserver(1)
3464           for details).
3465
3466       gitcvs.dbTableNamePrefix
3467           Database table name prefix. Prepended to the names of any database
3468           tables used, allowing a single database to be used for several
3469           repositories. Supports variable substitution (see git-cvsserver(1)
3470           for details). Any non-alphabetic characters will be replaced with
3471           underscores.
3472
3473       All gitcvs variables except for gitcvs.usecrlfattr and gitcvs.allBinary
3474       can also be specified as gitcvs.<access_method>.<varname> (where
3475       access_method is one of "ext" and "pserver") to make them apply only
3476       for the given access method.
3477

3488
3489       grep.column
3490           If set to true, enable the --column option by default.
3491
3492       grep.patternType
3493           Set the default matching behavior. Using a value of basic,
3494           extended, fixed, or perl will enable the --basic-regexp,
3495           --extended-regexp, --fixed-strings, or --perl-regexp option
3496           accordingly, while the value default will use the
3497           grep.extendedRegexp option to choose between basic and extended.
3498
3499       grep.extendedRegexp
3500           If set to true, enable --extended-regexp option by default. This
3501           option is ignored when the grep.patternType option is set to a
3502           value other than default.
3503
3504       grep.threads
3505           Number of grep worker threads to use. If unset (or set to 0), Git
3506           will use as many threads as the number of logical cores available.
3507
3508       grep.fullName
3509           If set to true, enable --full-name option by default.
3510
3511       grep.fallbackToNoIndex
3512           If set to true, fall back to git grep --no-index if git grep is
3513           executed outside of a git repository. Defaults to false.
3514
3515       gpg.program
3516           Use this custom program instead of "gpg" found on $PATH when making
3517           or verifying a PGP signature. The program must support the same
3518           command-line interface as GPG, namely, to verify a detached
3519           signature, "gpg --verify $signature - <$file" is run, and the
3520           program is expected to signal a good signature by exiting with code
3521           0. To generate an ASCII-armored detached signature, the standard
3522           input of "gpg -bsau $key" is fed with the contents to be signed,
3523           and the program is expected to send the result to its standard
3524           output.
3525
3526       gpg.format
3527           Specifies which key format to use when signing with --gpg-sign.
3528           Default is "openpgp". Other possible values are "x509", "ssh".
3529
3530           See gitformat-signature(5) for the signature format, which differs
3531           based on the selected gpg.format.
3532
3533       gpg.<format>.program
3534           Use this to customize the program used for the signing format you
3535           chose. (see gpg.program and gpg.format) gpg.program can still be
3536           used as a legacy synonym for gpg.openpgp.program. The default value
3537           for gpg.x509.program is "gpgsm" and gpg.ssh.program is
3538           "ssh-keygen".
3539
3540       gpg.minTrustLevel
3541           Specifies a minimum trust level for signature verification. If this
3542           option is unset, then signature verification for merge operations
3543           requires a key with at least marginal trust. Other operations that
3544           perform signature verification require a key with at least
3545           undefined trust. Setting this option overrides the required
3546           trust-level for all operations. Supported values, in increasing
3547           order of significance:
3548
3549undefined
3550
3551never
3552
3553marginal
3554
3555fully
3556
3557ultimate
3558
3559       gpg.ssh.defaultKeyCommand
3560           This command will be run when user.signingkey is not set and a ssh
3561           signature is requested. On successful exit a valid ssh public key
3562           prefixed with key:: is expected in the first line of its output.
3563           This allows for a script doing a dynamic lookup of the correct
3564           public key when it is impractical to statically configure
3565           user.signingKey. For example when keys or SSH Certificates are
3566           rotated frequently or selection of the right key depends on
3567           external factors unknown to git.
3568
3569       gpg.ssh.allowedSignersFile
3570           A file containing ssh public keys which you are willing to trust.
3571           The file consists of one or more lines of principals followed by an
3572           ssh public key. e.g.: user1@example.com,user2@example.com ssh-rsa
3573           AAAAX1...  See ssh-keygen(1) "ALLOWED SIGNERS" for details. The
3574           principal is only used to identify the key and is available when
3575           verifying a signature.
3576
3577           SSH has no concept of trust levels like gpg does. To be able to
3578           differentiate between valid signatures and trusted signatures the
3579           trust level of a signature verification is set to fully when the
3580           public key is present in the allowedSignersFile. Otherwise the
3581           trust level is undefined and git verify-commit/tag will fail.
3582
3583           This file can be set to a location outside of the repository and
3584           every developer maintains their own trust store. A central
3585           repository server could generate this file automatically from ssh
3586           keys with push access to verify the code against. In a corporate
3587           setting this file is probably generated at a global location from
3588           automation that already handles developer ssh keys.
3589
3590           A repository that only allows signed commits can store the file in
3591           the repository itself using a path relative to the top-level of the
3592           working tree. This way only committers with an already valid key
3593           can add or change keys in the keyring.
3594
3595           Since OpensSSH 8.8 this file allows specifying a key lifetime using
3596           valid-after & valid-before options. Git will mark signatures as
3597           valid if the signing key was valid at the time of the signature’s
3598           creation. This allows users to change a signing key without
3599           invalidating all previously made signatures.
3600
3601           Using a SSH CA key with the cert-authority option (see
3602           ssh-keygen(1) "CERTIFICATES") is also valid.
3603
3604       gpg.ssh.revocationFile
3605           Either a SSH KRL or a list of revoked public keys (without the
3606           principal prefix). See ssh-keygen(1) for details. If a public key
3607           is found in this file then it will always be treated as having
3608           trust level "never" and signatures will show as invalid.
3609
3610       gui.commitMsgWidth
3611           Defines how wide the commit message window is in the git-gui(1).
3612           "75" is the default.
3613
3614       gui.diffContext
3615           Specifies how many context lines should be used in calls to diff
3616           made by the git-gui(1). The default is "5".
3617
3618       gui.displayUntracked
3619           Determines if git-gui(1) shows untracked files in the file list.
3620           The default is "true".
3621
3622       gui.encoding
3623           Specifies the default character encoding to use for displaying of
3624           file contents in git-gui(1) and gitk(1). It can be overridden by
3625           setting the encoding attribute for relevant files (see
3626           gitattributes(5)). If this option is not set, the tools default to
3627           the locale encoding.
3628
3629       gui.matchTrackingBranch
3630           Determines if new branches created with git-gui(1) should default
3631           to tracking remote branches with matching names or not. Default:
3632           "false".
3633
3634       gui.newBranchTemplate
3635           Is used as a suggested name when creating new branches using the
3636           git-gui(1).
3637
3638       gui.pruneDuringFetch
3639           "true" if git-gui(1) should prune remote-tracking branches when
3640           performing a fetch. The default value is "false".
3641
3642       gui.trustmtime
3643           Determines if git-gui(1) should trust the file modification
3644           timestamp or not. By default the timestamps are not trusted.
3645
3646       gui.spellingDictionary
3647           Specifies the dictionary used for spell checking commit messages in
3648           the git-gui(1). When set to "none" spell checking is turned off.
3649
3650       gui.fastCopyBlame
3651           If true, git gui blame uses -C instead of -C -C for original
3652           location detection. It makes blame significantly faster on huge
3653           repositories at the expense of less thorough copy detection.
3654
3655       gui.copyBlameThreshold
3656           Specifies the threshold to use in git gui blame original location
3657           detection, measured in alphanumeric characters. See the git-
3658           blame(1) manual for more information on copy detection.
3659
3660       gui.blamehistoryctx
3661           Specifies the radius of history context in days to show in gitk(1)
3662           for the selected commit, when the Show History Context menu item is
3663           invoked from git gui blame. If this variable is set to zero, the
3664           whole history is shown.
3665
3666       guitool.<name>.cmd
3667           Specifies the shell command line to execute when the corresponding
3668           item of the git-gui(1) Tools menu is invoked. This option is
3669           mandatory for every tool. The command is executed from the root of
3670           the working directory, and in the environment it receives the name
3671           of the tool as GIT_GUITOOL, the name of the currently selected file
3672           as FILENAME, and the name of the current branch as CUR_BRANCH (if
3673           the head is detached, CUR_BRANCH is empty).
3674
3675       guitool.<name>.needsFile
3676           Run the tool only if a diff is selected in the GUI. It guarantees
3677           that FILENAME is not empty.
3678
3679       guitool.<name>.noConsole
3680           Run the command silently, without creating a window to display its
3681           output.
3682
3683       guitool.<name>.noRescan
3684           Don’t rescan the working directory for changes after the tool
3685           finishes execution.
3686
3687       guitool.<name>.confirm
3688           Show a confirmation dialog before actually running the tool.
3689
3690       guitool.<name>.argPrompt
3691           Request a string argument from the user, and pass it to the tool
3692           through the ARGS environment variable. Since requesting an argument
3693           implies confirmation, the confirm option has no effect if this is
3694           enabled. If the option is set to true, yes, or 1, the dialog uses a
3695           built-in generic prompt; otherwise the exact value of the variable
3696           is used.
3697
3698       guitool.<name>.revPrompt
3699           Request a single valid revision from the user, and set the REVISION
3700           environment variable. In other aspects this option is similar to
3701           argPrompt, and can be used together with it.
3702
3703       guitool.<name>.revUnmerged
3704           Show only unmerged branches in the revPrompt subdialog. This is
3705           useful for tools similar to merge or rebase, but not for things
3706           like checkout or reset.
3707
3708       guitool.<name>.title
3709           Specifies the title to use for the prompt dialog. The default is
3710           the tool name.
3711
3712       guitool.<name>.prompt
3713           Specifies the general prompt string to display at the top of the
3714           dialog, before subsections for argPrompt and revPrompt. The default
3715           value includes the actual command.
3716
3717       help.browser
3718           Specify the browser that will be used to display help in the web
3719           format. See git-help(1).
3720
3721       help.format
3722           Override the default help format used by git-help(1). Values man,
3723           info, web and html are supported.  man is the default.  web and
3724           html are the same.
3725
3726       help.autoCorrect
3727           If git detects typos and can identify exactly one valid command
3728           similar to the error, git will try to suggest the correct command
3729           or even run the suggestion automatically. Possible config values
3730           are:
3731
3732           •   0 (default): show the suggested command.
3733
3734           •   positive number: run the suggested command after specified
3735               deciseconds (0.1 sec).
3736
3737           •   "immediate": run the suggested command immediately.
3738
3739           •   "prompt": show the suggestion and prompt for confirmation to
3740               run the command.
3741
3742           •   "never": don’t run or show any suggested command.
3743
3744       help.htmlPath
3745           Specify the path where the HTML documentation resides. File system
3746           paths and URLs are supported. HTML pages will be prefixed with this
3747           path when help is displayed in the web format. This defaults to the
3748           documentation path of your Git installation.
3749
3750       http.proxy
3751           Override the HTTP proxy, normally configured using the http_proxy,
3752           https_proxy, and all_proxy environment variables (see curl(1)). In
3753           addition to the syntax understood by curl, it is possible to
3754           specify a proxy string with a user name but no password, in which
3755           case git will attempt to acquire one in the same way it does for
3756           other credentials. See gitcredentials(7) for more information. The
3757           syntax thus is [protocol://][user[:password]@]proxyhost[:port].
3758           This can be overridden on a per-remote basis; see
3759           remote.<name>.proxy
3760
3761       http.proxyAuthMethod
3762           Set the method with which to authenticate against the HTTP proxy.
3763           This only takes effect if the configured proxy string contains a
3764           user name part (i.e. is of the form user@host or user@host:port).
3765           This can be overridden on a per-remote basis; see
3766           remote.<name>.proxyAuthMethod. Both can be overridden by the
3767           GIT_HTTP_PROXY_AUTHMETHOD environment variable. Possible values
3768           are:
3769
3770anyauth - Automatically pick a suitable authentication method.
3771               It is assumed that the proxy answers an unauthenticated request
3772               with a 407 status code and one or more Proxy-authenticate
3773               headers with supported authentication methods. This is the
3774               default.
3775
3776basic - HTTP Basic authentication
3777
3778digest - HTTP Digest authentication; this prevents the password
3779               from being transmitted to the proxy in clear text
3780
3781negotiate - GSS-Negotiate authentication (compare the
3782               --negotiate option of curl(1))
3783
3784ntlm - NTLM authentication (compare the --ntlm option of
3785               curl(1))
3786
3787       http.proxySSLCert
3788           The pathname of a file that stores a client certificate to use to
3789           authenticate with an HTTPS proxy. Can be overridden by the
3790           GIT_PROXY_SSL_CERT environment variable.
3791
3792       http.proxySSLKey
3793           The pathname of a file that stores a private key to use to
3794           authenticate with an HTTPS proxy. Can be overridden by the
3795           GIT_PROXY_SSL_KEY environment variable.
3796
3797       http.proxySSLCertPasswordProtected
3798           Enable Git’s password prompt for the proxy SSL certificate.
3799           Otherwise OpenSSL will prompt the user, possibly many times, if the
3800           certificate or private key is encrypted. Can be overridden by the
3801           GIT_PROXY_SSL_CERT_PASSWORD_PROTECTED environment variable.
3802
3803       http.proxySSLCAInfo
3804           Pathname to the file containing the certificate bundle that should
3805           be used to verify the proxy with when using an HTTPS proxy. Can be
3806           overridden by the GIT_PROXY_SSL_CAINFO environment variable.
3807
3808       http.emptyAuth
3809           Attempt authentication without seeking a username or password. This
3810           can be used to attempt GSS-Negotiate authentication without
3811           specifying a username in the URL, as libcurl normally requires a
3812           username for authentication.
3813
3814       http.delegation
3815           Control GSSAPI credential delegation. The delegation is disabled by
3816           default in libcurl since version 7.21.7. Set parameter to tell the
3817           server what it is allowed to delegate when it comes to user
3818           credentials. Used with GSS/kerberos. Possible values are:
3819
3820none - Don’t allow any delegation.
3821
3822policy - Delegates if and only if the OK-AS-DELEGATE flag is
3823               set in the Kerberos service ticket, which is a matter of realm
3824               policy.
3825
3826always - Unconditionally allow the server to delegate.
3827
3828       http.extraHeader
3829           Pass an additional HTTP header when communicating with a server. If
3830           more than one such entry exists, all of them are added as extra
3831           headers. To allow overriding the settings inherited from the system
3832           config, an empty value will reset the extra headers to the empty
3833           list.
3834
3835       http.cookieFile
3836           The pathname of a file containing previously stored cookie lines,
3837           which should be used in the Git http session, if they match the
3838           server. The file format of the file to read cookies from should be
3839           plain HTTP headers or the Netscape/Mozilla cookie file format (see
3840           curl(1)). NOTE that the file specified with http.cookieFile is used
3841           only as input unless http.saveCookies is set.
3842
3843       http.saveCookies
3844           If set, store cookies received during requests to the file
3845           specified by http.cookieFile. Has no effect if http.cookieFile is
3846           unset.
3847
3848       http.version
3849           Use the specified HTTP protocol version when communicating with a
3850           server. If you want to force the default. The available and default
3851           version depend on libcurl. Currently the possible values of this
3852           option are:
3853
3854           •   HTTP/2
3855
3856           •   HTTP/1.1
3857
3858       http.curloptResolve
3859           Hostname resolution information that will be used first by libcurl
3860           when sending HTTP requests. This information should be in one of
3861           the following formats:
3862
3863           •   [+]HOST:PORT:ADDRESS[,ADDRESS]
3864
3865           •   -HOST:PORT
3866
3867           The first format redirects all requests to the given HOST:PORT to
3868           the provided ADDRESS(s). The second format clears all previous
3869           config values for that HOST:PORT combination. To allow easy
3870           overriding of all the settings inherited from the system config, an
3871           empty value will reset all resolution information to the empty
3872           list.
3873
3874       http.sslVersion
3875           The SSL version to use when negotiating an SSL connection, if you
3876           want to force the default. The available and default version depend
3877           on whether libcurl was built against NSS or OpenSSL and the
3878           particular configuration of the crypto library in use. Internally
3879           this sets the CURLOPT_SSL_VERSION option; see the libcurl
3880           documentation for more details on the format of this option and for
3881           the ssl version supported. Currently the possible values of this
3882           option are:
3883
3884           •   sslv2
3885
3886           •   sslv3
3887
3888           •   tlsv1
3889
3890           •   tlsv1.0
3891
3892           •   tlsv1.1
3893
3894           •   tlsv1.2
3895
3896           •   tlsv1.3
3897
3898           Can be overridden by the GIT_SSL_VERSION environment variable. To
3899           force git to use libcurl’s default ssl version and ignore any
3900           explicit http.sslversion option, set GIT_SSL_VERSION to the empty
3901           string.
3902
3903       http.sslCipherList
3904           A list of SSL ciphers to use when negotiating an SSL connection.
3905           The available ciphers depend on whether libcurl was built against
3906           NSS or OpenSSL and the particular configuration of the crypto
3907           library in use. Internally this sets the CURLOPT_SSL_CIPHER_LIST
3908           option; see the libcurl documentation for more details on the
3909           format of this list.
3910
3911           Can be overridden by the GIT_SSL_CIPHER_LIST environment variable.
3912           To force git to use libcurl’s default cipher list and ignore any
3913           explicit http.sslCipherList option, set GIT_SSL_CIPHER_LIST to the
3914           empty string.
3915
3916       http.sslVerify
3917           Whether to verify the SSL certificate when fetching or pushing over
3918           HTTPS. Defaults to true. Can be overridden by the GIT_SSL_NO_VERIFY
3919           environment variable.
3920
3921       http.sslCert
3922           File containing the SSL certificate when fetching or pushing over
3923           HTTPS. Can be overridden by the GIT_SSL_CERT environment variable.
3924
3925       http.sslKey
3926           File containing the SSL private key when fetching or pushing over
3927           HTTPS. Can be overridden by the GIT_SSL_KEY environment variable.
3928
3929       http.sslCertPasswordProtected
3930           Enable Git’s password prompt for the SSL certificate. Otherwise
3931           OpenSSL will prompt the user, possibly many times, if the
3932           certificate or private key is encrypted. Can be overridden by the
3933           GIT_SSL_CERT_PASSWORD_PROTECTED environment variable.
3934
3935       http.sslCAInfo
3936           File containing the certificates to verify the peer with when
3937           fetching or pushing over HTTPS. Can be overridden by the
3938           GIT_SSL_CAINFO environment variable.
3939
3940       http.sslCAPath
3941           Path containing files with the CA certificates to verify the peer
3942           with when fetching or pushing over HTTPS. Can be overridden by the
3943           GIT_SSL_CAPATH environment variable.
3944
3945       http.sslBackend
3946           Name of the SSL backend to use (e.g. "openssl" or "schannel"). This
3947           option is ignored if cURL lacks support for choosing the SSL
3948           backend at runtime.
3949
3950       http.schannelCheckRevoke
3951           Used to enforce or disable certificate revocation checks in cURL
3952           when http.sslBackend is set to "schannel". Defaults to true if
3953           unset. Only necessary to disable this if Git consistently errors
3954           and the message is about checking the revocation status of a
3955           certificate. This option is ignored if cURL lacks support for
3956           setting the relevant SSL option at runtime.
3957
3958       http.schannelUseSSLCAInfo
3959           As of cURL v7.60.0, the Secure Channel backend can use the
3960           certificate bundle provided via http.sslCAInfo, but that would
3961           override the Windows Certificate Store. Since this is not desirable
3962           by default, Git will tell cURL not to use that bundle by default
3963           when the schannel backend was configured via http.sslBackend,
3964           unless http.schannelUseSSLCAInfo overrides this behavior.
3965
3966       http.pinnedPubkey
3967           Public key of the https service. It may either be the filename of a
3968           PEM or DER encoded public key file or a string starting with
3969           sha256// followed by the base64 encoded sha256 hash of the public
3970           key. See also libcurl CURLOPT_PINNEDPUBLICKEY. git will exit with
3971           an error if this option is set but not supported by cURL.
3972
3973       http.sslTry
3974           Attempt to use AUTH SSL/TLS and encrypted data transfers when
3975           connecting via regular FTP protocol. This might be needed if the
3976           FTP server requires it for security reasons or you wish to connect
3977           securely whenever remote FTP server supports it. Default is false
3978           since it might trigger certificate verification errors on
3979           misconfigured servers.
3980
3981       http.maxRequests
3982           How many HTTP requests to launch in parallel. Can be overridden by
3983           the GIT_HTTP_MAX_REQUESTS environment variable. Default is 5.
3984
3985       http.minSessions
3986           The number of curl sessions (counted across slots) to be kept
3987           across requests. They will not be ended with curl_easy_cleanup()
3988           until http_cleanup() is invoked. If USE_CURL_MULTI is not defined,
3989           this value will be capped at 1. Defaults to 1.
3990
3991       http.postBuffer
3992           Maximum size in bytes of the buffer used by smart HTTP transports
3993           when POSTing data to the remote system. For requests larger than
3994           this buffer size, HTTP/1.1 and Transfer-Encoding: chunked is used
3995           to avoid creating a massive pack file locally. Default is 1 MiB,
3996           which is sufficient for most requests.
3997
3998           Note that raising this limit is only effective for disabling
3999           chunked transfer encoding and therefore should be used only where
4000           the remote server or a proxy only supports HTTP/1.0 or is
4001           noncompliant with the HTTP standard. Raising this is not, in
4002           general, an effective solution for most push problems, but can
4003           increase memory consumption significantly since the entire buffer
4004           is allocated even for small pushes.
4005
4006       http.lowSpeedLimit, http.lowSpeedTime
4007           If the HTTP transfer speed, in bytes per second, is less than
4008           http.lowSpeedLimit for longer than http.lowSpeedTime seconds, the
4009           transfer is aborted. Can be overridden by the
4010           GIT_HTTP_LOW_SPEED_LIMIT and GIT_HTTP_LOW_SPEED_TIME environment
4011           variables.
4012
4013       http.noEPSV
4014           A boolean which disables using of EPSV ftp command by curl. This
4015           can be helpful with some "poor" ftp servers which don’t support
4016           EPSV mode. Can be overridden by the GIT_CURL_FTP_NO_EPSV
4017           environment variable. Default is false (curl will use EPSV).
4018
4019       http.userAgent
4020           The HTTP USER_AGENT string presented to an HTTP server. The default
4021           value represents the version of the Git client such as git/1.7.1.
4022           This option allows you to override this value to a more common
4023           value such as Mozilla/4.0. This may be necessary, for instance, if
4024           connecting through a firewall that restricts HTTP connections to a
4025           set of common USER_AGENT strings (but not including those like
4026           git/1.7.1). Can be overridden by the GIT_HTTP_USER_AGENT
4027           environment variable.
4028
4029       http.followRedirects
4030           Whether git should follow HTTP redirects. If set to true, git will
4031           transparently follow any redirect issued by a server it encounters.
4032           If set to false, git will treat all redirects as errors. If set to
4033           initial, git will follow redirects only for the initial request to
4034           a remote, but not for subsequent follow-up HTTP requests. Since git
4035           uses the redirected URL as the base for the follow-up requests,
4036           this is generally sufficient. The default is initial.
4037
4038       http.<url>.*
4039           Any of the http.* options above can be applied selectively to some
4040           URLs. For a config key to match a URL, each element of the config
4041           key is compared to that of the URL, in the following order:
4042
4043            1. Scheme (e.g., https in https://example.com/). This field must
4044               match exactly between the config key and the URL.
4045
4046            2. Host/domain name (e.g., example.com in https://example.com/).
4047               This field must match between the config key and the URL. It is
4048               possible to specify a * as part of the host name to match all
4049               subdomains at this level.  https://*.example.com/ for example
4050               would match https://foo.example.com/, but not
4051               https://foo.bar.example.com/.
4052
4053            3. Port number (e.g., 8080 in http://example.com:8080/). This
4054               field must match exactly between the config key and the URL.
4055               Omitted port numbers are automatically converted to the correct
4056               default for the scheme before matching.
4057
4058            4. Path (e.g., repo.git in https://example.com/repo.git). The path
4059               field of the config key must match the path field of the URL
4060               either exactly or as a prefix of slash-delimited path elements.
4061               This means a config key with path foo/ matches URL path
4062               foo/bar. A prefix can only match on a slash (/) boundary.
4063               Longer matches take precedence (so a config key with path
4064               foo/bar is a better match to URL path foo/bar than a config key
4065               with just path foo/).
4066
4067            5. User name (e.g., user in https://user@example.com/repo.git). If
4068               the config key has a user name it must match the user name in
4069               the URL exactly. If the config key does not have a user name,
4070               that config key will match a URL with any user name (including
4071               none), but at a lower precedence than a config key with a user
4072               name.
4073
4074           The list above is ordered by decreasing precedence; a URL that
4075           matches a config key’s path is preferred to one that matches its
4076           user name. For example, if the URL is
4077           https://user@example.com/foo/bar a config key match of
4078           https://example.com/foo will be preferred over a config key match
4079           of https://user@example.com.
4080
4081           All URLs are normalized before attempting any matching (the
4082           password part, if embedded in the URL, is always ignored for
4083           matching purposes) so that equivalent URLs that are simply spelled
4084           differently will match properly. Environment variable settings
4085           always override any matches. The URLs that are matched against are
4086           those given directly to Git commands. This means any URLs visited
4087           as a result of a redirection do not participate in matching.
4088
4089       i18n.commitEncoding
4090           Character encoding the commit messages are stored in; Git itself
4091           does not care per se, but this information is necessary e.g. when
4092           importing commits from emails or in the gitk graphical history
4093           browser (and possibly in other places in the future or in other
4094           porcelains). See e.g.  git-mailinfo(1). Defaults to utf-8.
4095
4096       i18n.logOutputEncoding
4097           Character encoding the commit messages are converted to when
4098           running git log and friends.
4099
4100       imap.folder
4101           The folder to drop the mails into, which is typically the Drafts
4102           folder. For example: "INBOX.Drafts", "INBOX/Drafts" or
4103           "[Gmail]/Drafts". Required.
4104
4105       imap.tunnel
4106           Command used to set up a tunnel to the IMAP server through which
4107           commands will be piped instead of using a direct network connection
4108           to the server. Required when imap.host is not set.
4109
4110       imap.host
4111           A URL identifying the server. Use an imap:// prefix for non-secure
4112           connections and an imaps:// prefix for secure connections. Ignored
4113           when imap.tunnel is set, but required otherwise.
4114
4115       imap.user
4116           The username to use when logging in to the server.
4117
4118       imap.pass
4119           The password to use when logging in to the server.
4120
4121       imap.port
4122           An integer port number to connect to on the server. Defaults to 143
4123           for imap:// hosts and 993 for imaps:// hosts. Ignored when
4124           imap.tunnel is set.
4125
4126       imap.sslverify
4127           A boolean to enable/disable verification of the server certificate
4128           used by the SSL/TLS connection. Default is true. Ignored when
4129           imap.tunnel is set.
4130
4131       imap.preformattedHTML
4132           A boolean to enable/disable the use of html encoding when sending a
4133           patch. An html encoded patch will be bracketed with <pre> and have
4134           a content type of text/html. Ironically, enabling this option
4135           causes Thunderbird to send the patch as a plain/text, format=fixed
4136           email. Default is false.
4137
4138       imap.authMethod
4139           Specify the authentication method for authenticating with the IMAP
4140           server. If Git was built with the NO_CURL option, or if your curl
4141           version is older than 7.34.0, or if you’re running git-imap-send
4142           with the --no-curl option, the only supported method is CRAM-MD5.
4143           If this is not set then git imap-send uses the basic IMAP plaintext
4144           LOGIN command.
4145
4146       include.path, includeIf.<condition>.path
4147           Special variables to include other configuration files. See the
4148           "CONFIGURATION FILE" section in the main git-config(1)
4149           documentation, specifically the "Includes" and "Conditional
4150           Includes" subsections.
4151
4152       index.recordEndOfIndexEntries
4153           Specifies whether the index file should include an "End Of Index
4154           Entry" section. This reduces index load time on multiprocessor
4155           machines but produces a message "ignoring EOIE extension" when
4156           reading the index using Git versions before 2.20. Defaults to true
4157           if index.threads has been explicitly enabled, false otherwise.
4158
4159       index.recordOffsetTable
4160           Specifies whether the index file should include an "Index Entry
4161           Offset Table" section. This reduces index load time on
4162           multiprocessor machines but produces a message "ignoring IEOT
4163           extension" when reading the index using Git versions before 2.20.
4164           Defaults to true if index.threads has been explicitly enabled,
4165           false otherwise.
4166
4167       index.sparse
4168           When enabled, write the index using sparse-directory entries. This
4169           has no effect unless core.sparseCheckout and
4170           core.sparseCheckoutCone are both enabled. Defaults to false.
4171
4172       index.threads
4173           Specifies the number of threads to spawn when loading the index.
4174           This is meant to reduce index load time on multiprocessor machines.
4175           Specifying 0 or true will cause Git to auto-detect the number of
4176           CPUs and set the number of threads accordingly. Specifying 1 or
4177           false will disable multithreading. Defaults to true.
4178
4179       index.version
4180           Specify the version with which new index files should be
4181           initialized. This does not affect existing repositories. If
4182           feature.manyFiles is enabled, then the default is 4.
4183
4184       index.skipHash
4185           When enabled, do not compute the trailing hash for the index file.
4186           This accelerates Git commands that manipulate the index, such as
4187           git add, git commit, or git status. Instead of storing the
4188           checksum, write a trailing set of bytes with value zero, indicating
4189           that the computation was skipped.
4190
4191           If you enable index.skipHash, then Git clients older than 2.13.0
4192           will refuse to parse the index and Git clients older than 2.40.0
4193           will report an error during git fsck.
4194
4195       init.templateDir
4196           Specify the directory from which templates will be copied. (See the
4197           "TEMPLATE DIRECTORY" section of git-init(1).)
4198
4199       init.defaultBranch
4200           Allows overriding the default branch name e.g. when initializing a
4201           new repository.
4202
4203       instaweb.browser
4204           Specify the program that will be used to browse your working
4205           repository in gitweb. See git-instaweb(1).
4206
4207       instaweb.httpd
4208           The HTTP daemon command-line to start gitweb on your working
4209           repository. See git-instaweb(1).
4210
4211       instaweb.local
4212           If true the web server started by git-instaweb(1) will be bound to
4213           the local IP (127.0.0.1).
4214
4215       instaweb.modulePath
4216           The default module path for git-instaweb(1) to use instead of
4217           /usr/lib/apache2/modules. Only used if httpd is Apache.
4218
4219       instaweb.port
4220           The port number to bind the gitweb httpd to. See git-instaweb(1).
4221
4222       interactive.singleKey
4223           In interactive commands, allow the user to provide one-letter input
4224           with a single key (i.e., without hitting enter). Currently this is
4225           used by the --patch mode of git-add(1), git-checkout(1), git-
4226           restore(1), git-commit(1), git-reset(1), and git-stash(1). Note
4227           that this setting is silently ignored if portable keystroke input
4228           is not available; requires the Perl module Term::ReadKey.
4229
4230       interactive.diffFilter
4231           When an interactive command (such as git add --patch) shows a
4232           colorized diff, git will pipe the diff through the shell command
4233           defined by this configuration variable. The command may mark up the
4234           diff further for human consumption, provided that it retains a
4235           one-to-one correspondence with the lines in the original diff.
4236           Defaults to disabled (no filtering).
4237
4238       log.abbrevCommit
4239           If true, makes git-log(1), git-show(1), and git-whatchanged(1)
4240           assume --abbrev-commit. You may override this option with
4241           --no-abbrev-commit.
4242
4243       log.date
4244           Set the default date-time mode for the log command. Setting a value
4245           for log.date is similar to using git log's --date option. See git-
4246           log(1) for details.
4247
4248           If the format is set to "auto:foo" and the pager is in use, format
4249           "foo" will be used for the date format. Otherwise, "default" will
4250           be used.
4251
4252       log.decorate
4253           Print out the ref names of any commits that are shown by the log
4254           command. If short is specified, the ref name prefixes refs/heads/,
4255           refs/tags/ and refs/remotes/ will not be printed. If full is
4256           specified, the full ref name (including prefix) will be printed. If
4257           auto is specified, then if the output is going to a terminal, the
4258           ref names are shown as if short were given, otherwise no ref names
4259           are shown. This is the same as the --decorate option of the git
4260           log.
4261
4262       log.initialDecorationSet
4263           By default, git log only shows decorations for certain known ref
4264           namespaces. If all is specified, then show all refs as decorations.
4265
4266       log.excludeDecoration
4267           Exclude the specified patterns from the log decorations. This is
4268           similar to the --decorate-refs-exclude command-line option, but the
4269           config option can be overridden by the --decorate-refs option.
4270
4271       log.diffMerges
4272           Set diff format to be used when --diff-merges=on is specified, see
4273           --diff-merges in git-log(1) for details. Defaults to separate.
4274
4275       log.follow
4276           If true, git log will act as if the --follow option was used when a
4277           single <path> is given. This has the same limitations as --follow,
4278           i.e. it cannot be used to follow multiple files and does not work
4279           well on non-linear history.
4280
4281       log.graphColors
4282           A list of colors, separated by commas, that can be used to draw
4283           history lines in git log --graph.
4284
4285       log.showRoot
4286           If true, the initial commit will be shown as a big creation event.
4287           This is equivalent to a diff against an empty tree. Tools like git-
4288           log(1) or git-whatchanged(1), which normally hide the root commit
4289           will now show it. True by default.
4290
4291       log.showSignature
4292           If true, makes git-log(1), git-show(1), and git-whatchanged(1)
4293           assume --show-signature.
4294
4295       log.mailmap
4296           If true, makes git-log(1), git-show(1), and git-whatchanged(1)
4297           assume --use-mailmap, otherwise assume --no-use-mailmap. True by
4298           default.
4299
4300       lsrefs.unborn
4301           May be "advertise" (the default), "allow", or "ignore". If
4302           "advertise", the server will respond to the client sending "unborn"
4303           (as described in gitprotocol-v2(5)) and will advertise support for
4304           this feature during the protocol v2 capability advertisement.
4305           "allow" is the same as "advertise" except that the server will not
4306           advertise support for this feature; this is useful for
4307           load-balanced servers that cannot be updated atomically (for
4308           example), since the administrator could configure "allow", then
4309           after a delay, configure "advertise".
4310
4311       mailinfo.scissors
4312           If true, makes git-mailinfo(1) (and therefore git-am(1)) act by
4313           default as if the --scissors option was provided on the
4314           command-line. When active, this feature removes everything from the
4315           message body before a scissors line (i.e. consisting mainly of
4316           ">8", "8<" and "-").
4317
4318       mailmap.file
4319           The location of an augmenting mailmap file. The default mailmap,
4320           located in the root of the repository, is loaded first, then the
4321           mailmap file pointed to by this variable. The location of the
4322           mailmap file may be in a repository subdirectory, or somewhere
4323           outside of the repository itself. See git-shortlog(1) and git-
4324           blame(1).
4325
4326       mailmap.blob
4327           Like mailmap.file, but consider the value as a reference to a blob
4328           in the repository. If both mailmap.file and mailmap.blob are given,
4329           both are parsed, with entries from mailmap.file taking precedence.
4330           In a bare repository, this defaults to HEAD:.mailmap. In a non-bare
4331           repository, it defaults to empty.
4332
4333       maintenance.auto
4334           This boolean config option controls whether some commands run git
4335           maintenance run --auto after doing their normal work. Defaults to
4336           true.
4337
4338       maintenance.strategy
4339           This string config option provides a way to specify one of a few
4340           recommended schedules for background maintenance. This only affects
4341           which tasks are run during git maintenance run --schedule=X
4342           commands, provided no --task=<task> arguments are provided.
4343           Further, if a maintenance.<task>.schedule config value is set, then
4344           that value is used instead of the one provided by
4345           maintenance.strategy. The possible strategy strings are:
4346
4347none: This default setting implies no tasks are run at any
4348               schedule.
4349
4350incremental: This setting optimizes for performing small
4351               maintenance activities that do not delete any data. This does
4352               not schedule the gc task, but runs the prefetch and
4353               commit-graph tasks hourly, the loose-objects and
4354               incremental-repack tasks daily, and the pack-refs task weekly.
4355
4356       maintenance.<task>.enabled
4357           This boolean config option controls whether the maintenance task
4358           with name <task> is run when no --task option is specified to git
4359           maintenance run. These config values are ignored if a --task option
4360           exists. By default, only maintenance.gc.enabled is true.
4361
4362       maintenance.<task>.schedule
4363           This config option controls whether or not the given <task> runs
4364           during a git maintenance run --schedule=<frequency> command. The
4365           value must be one of "hourly", "daily", or "weekly".
4366
4367       maintenance.commit-graph.auto
4368           This integer config option controls how often the commit-graph task
4369           should be run as part of git maintenance run --auto. If zero, then
4370           the commit-graph task will not run with the --auto option. A
4371           negative value will force the task to run every time. Otherwise, a
4372           positive value implies the command should run when the number of
4373           reachable commits that are not in the commit-graph file is at least
4374           the value of maintenance.commit-graph.auto. The default value is
4375           100.
4376
4377       maintenance.loose-objects.auto
4378           This integer config option controls how often the loose-objects
4379           task should be run as part of git maintenance run --auto. If zero,
4380           then the loose-objects task will not run with the --auto option. A
4381           negative value will force the task to run every time. Otherwise, a
4382           positive value implies the command should run when the number of
4383           loose objects is at least the value of
4384           maintenance.loose-objects.auto. The default value is 100.
4385
4386       maintenance.incremental-repack.auto
4387           This integer config option controls how often the
4388           incremental-repack task should be run as part of git maintenance
4389           run --auto. If zero, then the incremental-repack task will not run
4390           with the --auto option. A negative value will force the task to run
4391           every time. Otherwise, a positive value implies the command should
4392           run when the number of pack-files not in the multi-pack-index is at
4393           least the value of maintenance.incremental-repack.auto. The default
4394           value is 10.
4395
4396       man.viewer
4397           Specify the programs that may be used to display help in the man
4398           format. See git-help(1).
4399
4400       man.<tool>.cmd
4401           Specify the command to invoke the specified man viewer. The
4402           specified command is evaluated in shell with the man page passed as
4403           an argument. (See git-help(1).)
4404
4405       man.<tool>.path
4406           Override the path for the given tool that may be used to display
4407           help in the man format. See git-help(1).
4408
4409       merge.conflictStyle
4410           Specify the style in which conflicted hunks are written out to
4411           working tree files upon merge. The default is "merge", which shows
4412           a <<<<<<< conflict marker, changes made by one side, a =======
4413           marker, changes made by the other side, and then a >>>>>>> marker.
4414           An alternate style, "diff3", adds a ||||||| marker and the original
4415           text before the ======= marker. The "merge" style tends to produce
4416           smaller conflict regions than diff3, both because of the exclusion
4417           of the original text, and because when a subset of lines match on
4418           the two sides, they are just pulled out of the conflict region.
4419           Another alternate style, "zdiff3", is similar to diff3 but removes
4420           matching lines on the two sides from the conflict region when those
4421           matching lines appear near either the beginning or end of a
4422           conflict region.
4423
4424       merge.defaultToUpstream
4425           If merge is called without any commit argument, merge the upstream
4426           branches configured for the current branch by using their last
4427           observed values stored in their remote-tracking branches. The
4428           values of the branch.<current branch>.merge that name the branches
4429           at the remote named by branch.<current branch>.remote are
4430           consulted, and then they are mapped via remote.<remote>.fetch to
4431           their corresponding remote-tracking branches, and the tips of these
4432           tracking branches are merged. Defaults to true.
4433
4434       merge.ff
4435           By default, Git does not create an extra merge commit when merging
4436           a commit that is a descendant of the current commit. Instead, the
4437           tip of the current branch is fast-forwarded. When set to false,
4438           this variable tells Git to create an extra merge commit in such a
4439           case (equivalent to giving the --no-ff option from the command
4440           line). When set to only, only such fast-forward merges are allowed
4441           (equivalent to giving the --ff-only option from the command line).
4442
4443       merge.verifySignatures
4444           If true, this is equivalent to the --verify-signatures command line
4445           option. See git-merge(1) for details.
4446
4447       merge.branchdesc
4448           In addition to branch names, populate the log message with the
4449           branch description text associated with them. Defaults to false.
4450
4451       merge.log
4452           In addition to branch names, populate the log message with at most
4453           the specified number of one-line descriptions from the actual
4454           commits that are being merged. Defaults to false, and true is a
4455           synonym for 20.
4456
4457       merge.suppressDest
4458           By adding a glob that matches the names of integration branches to
4459           this multi-valued configuration variable, the default merge message
4460           computed for merges into these integration branches will omit "into
4461           <branch name>" from its title.
4462
4463           An element with an empty value can be used to clear the list of
4464           globs accumulated from previous configuration entries. When there
4465           is no merge.suppressDest variable defined, the default value of
4466           master is used for backward compatibility.
4467
4468       merge.renameLimit
4469           The number of files to consider in the exhaustive portion of rename
4470           detection during a merge. If not specified, defaults to the value
4471           of diff.renameLimit. If neither merge.renameLimit nor
4472           diff.renameLimit are specified, currently defaults to 7000. This
4473           setting has no effect if rename detection is turned off.
4474
4475       merge.renames
4476           Whether Git detects renames. If set to "false", rename detection is
4477           disabled. If set to "true", basic rename detection is enabled.
4478           Defaults to the value of diff.renames.
4479
4480       merge.directoryRenames
4481           Whether Git detects directory renames, affecting what happens at
4482           merge time to new files added to a directory on one side of history
4483           when that directory was renamed on the other side of history. If
4484           merge.directoryRenames is set to "false", directory rename
4485           detection is disabled, meaning that such new files will be left
4486           behind in the old directory. If set to "true", directory rename
4487           detection is enabled, meaning that such new files will be moved
4488           into the new directory. If set to "conflict", a conflict will be
4489           reported for such paths. If merge.renames is false,
4490           merge.directoryRenames is ignored and treated as false. Defaults to
4491           "conflict".
4492
4493       merge.renormalize
4494           Tell Git that canonical representation of files in the repository
4495           has changed over time (e.g. earlier commits record text files with
4496           CRLF line endings, but recent ones use LF line endings). In such a
4497           repository, Git can convert the data recorded in commits to a
4498           canonical form before performing a merge to reduce unnecessary
4499           conflicts. For more information, see section "Merging branches with
4500           differing checkin/checkout attributes" in gitattributes(5).
4501
4502       merge.stat
4503           Whether to print the diffstat between ORIG_HEAD and the merge
4504           result at the end of the merge. True by default.
4505
4506       merge.autoStash
4507           When set to true, automatically create a temporary stash entry
4508           before the operation begins, and apply it after the operation ends.
4509           This means that you can run merge on a dirty worktree. However, use
4510           with care: the final stash application after a successful merge
4511           might result in non-trivial conflicts. This option can be
4512           overridden by the --no-autostash and --autostash options of git-
4513           merge(1). Defaults to false.
4514
4515       merge.tool
4516           Controls which merge tool is used by git-mergetool(1). The list
4517           below shows the valid built-in values. Any other value is treated
4518           as a custom merge tool and requires that a corresponding
4519           mergetool.<tool>.cmd variable is defined.
4520
4521       merge.guitool
4522           Controls which merge tool is used by git-mergetool(1) when the
4523           -g/--gui flag is specified. The list below shows the valid built-in
4524           values. Any other value is treated as a custom merge tool and
4525           requires that a corresponding mergetool.<guitool>.cmd variable is
4526           defined.

4637           conflicts were detected. Level 1 outputs only conflicts, 2 outputs
4638           conflicts and file changes. Level 5 and above outputs debugging
4639           information. The default is level 2. Can be overridden by the
4640           GIT_MERGE_VERBOSITY environment variable.
4641
4642       merge.<driver>.name
4643           Defines a human-readable name for a custom low-level merge driver.
4644           See gitattributes(5) for details.
4645
4646       merge.<driver>.driver
4647           Defines the command that implements a custom low-level merge
4648           driver. See gitattributes(5) for details.
4649
4650       merge.<driver>.recursive
4651           Names a low-level merge driver to be used when performing an
4652           internal merge between common ancestors. See gitattributes(5) for
4653           details.
4654
4655       mergetool.<tool>.path
4656           Override the path for the given tool. This is useful in case your
4657           tool is not in the PATH.
4658
4659       mergetool.<tool>.cmd
4660           Specify the command to invoke the specified merge tool. The
4661           specified command is evaluated in shell with the following
4662           variables available: BASE is the name of a temporary file
4663           containing the common base of the files to be merged, if available;
4664           LOCAL is the name of a temporary file containing the contents of
4665           the file on the current branch; REMOTE is the name of a temporary
4666           file containing the contents of the file from the branch being
4667           merged; MERGED contains the name of the file to which the merge
4668           tool should write the results of a successful merge.
4669
4670       mergetool.<tool>.hideResolved
4671           Allows the user to override the global mergetool.hideResolved value
4672           for a specific tool. See mergetool.hideResolved for the full
4673           description.
4674
4675       mergetool.<tool>.trustExitCode
4676           For a custom merge command, specify whether the exit code of the
4677           merge command can be used to determine whether the merge was
4678           successful. If this is not set to true then the merge target file
4679           timestamp is checked, and the merge is assumed to have been
4680           successful if the file has been updated; otherwise, the user is
4681           prompted to indicate the success of the merge.
4682
4683       mergetool.meld.hasOutput
4684           Older versions of meld do not support the --output option. Git will
4685           attempt to detect whether meld supports --output by inspecting the
4686           output of meld --help. Configuring mergetool.meld.hasOutput will
4687           make Git skip these checks and use the configured value instead.
4688           Setting mergetool.meld.hasOutput to true tells Git to
4689           unconditionally use the --output option, and false avoids using
4690           --output.
4691
4692       mergetool.meld.useAutoMerge
4693           When the --auto-merge is given, meld will merge all non-conflicting
4694           parts automatically, highlight the conflicting parts, and wait for
4695           user decision. Setting mergetool.meld.useAutoMerge to true tells
4696           Git to unconditionally use the --auto-merge option with meld.
4697           Setting this value to auto makes git detect whether --auto-merge is
4698           supported and will only use --auto-merge when available. A value of
4699           false avoids using --auto-merge altogether, and is the default
4700           value.
4701
4702       mergetool.vimdiff.layout
4703           The vimdiff backend uses this variable to control how its split
4704           windows appear. Applies even if you are using Neovim (nvim) or gVim
4705           (gvim) as the merge tool. See BACKEND SPECIFIC HINTS section in
4706           git-mergetool(1). for details.
4707
4708       mergetool.hideResolved
4709           During a merge, Git will automatically resolve as many conflicts as
4710           possible and write the MERGED file containing conflict markers
4711           around any conflicts that it cannot resolve; LOCAL and REMOTE
4712           normally represent the versions of the file from before Git’s
4713           conflict resolution. This flag causes LOCAL and REMOTE to be
4714           overwritten so that only the unresolved conflicts are presented to
4715           the merge tool. Can be configured per-tool via the
4716           mergetool.<tool>.hideResolved configuration variable. Defaults to
4717           false.
4718
4719       mergetool.keepBackup
4720           After performing a merge, the original file with conflict markers
4721           can be saved as a file with a .orig extension. If this variable is
4722           set to false then this file is not preserved. Defaults to true
4723           (i.e. keep the backup files).
4724
4725       mergetool.keepTemporaries
4726           When invoking a custom merge tool, Git uses a set of temporary
4727           files to pass to the tool. If the tool returns an error and this
4728           variable is set to true, then these temporary files will be
4729           preserved; otherwise, they will be removed after the tool has
4730           exited. Defaults to false.
4731
4732       mergetool.writeToTemp
4733           Git writes temporary BASE, LOCAL, and REMOTE versions of
4734           conflicting files in the worktree by default. Git will attempt to
4735           use a temporary directory for these files when set true. Defaults
4736           to false.
4737
4738       mergetool.prompt
4739           Prompt before each invocation of the merge resolution program.
4740
4741       mergetool.guiDefault
4742           Set true to use the merge.guitool by default (equivalent to
4743           specifying the --gui argument), or auto to select merge.guitool or
4744           merge.tool depending on the presence of a DISPLAY environment
4745           variable value. The default is false, where the --gui argument must
4746           be provided explicitly for the merge.guitool to be used.
4747
4748       notes.mergeStrategy
4749           Which merge strategy to choose by default when resolving notes
4750           conflicts. Must be one of manual, ours, theirs, union, or
4751           cat_sort_uniq. Defaults to manual. See the "NOTES MERGE STRATEGIES"
4752           section of git-notes(1) for more information on each strategy.
4753
4754           This setting can be overridden by passing the --strategy option to
4755           git-notes(1).
4756
4757       notes.<name>.mergeStrategy
4758           Which merge strategy to choose when doing a notes merge into
4759           refs/notes/<name>. This overrides the more general
4760           "notes.mergeStrategy". See the "NOTES MERGE STRATEGIES" section in
4761           git-notes(1) for more information on the available strategies.
4762
4763       notes.displayRef
4764           Which ref (or refs, if a glob or specified more than once), in
4765           addition to the default set by core.notesRef or GIT_NOTES_REF, to
4766           read notes from when showing commit messages with the git log
4767           family of commands.
4768
4769           This setting can be overridden with the GIT_NOTES_DISPLAY_REF
4770           environment variable, which must be a colon separated list of refs
4771           or globs.
4772
4773           A warning will be issued for refs that do not exist, but a glob
4774           that does not match any refs is silently ignored.
4775
4776           This setting can be disabled by the --no-notes option to the git
4777           log family of commands, or by the --notes=<ref> option accepted by
4778           those commands.
4779
4780           The effective value of "core.notesRef" (possibly overridden by
4781           GIT_NOTES_REF) is also implicitly added to the list of refs to be
4782           displayed.
4783
4784       notes.rewrite.<command>
4785           When rewriting commits with <command> (currently amend or rebase),
4786           if this variable is false, git will not copy notes from the
4787           original to the rewritten commit. Defaults to true. See also
4788           "notes.rewriteRef" below.
4789
4790           This setting can be overridden with the GIT_NOTES_REWRITE_REF
4791           environment variable, which must be a colon separated list of refs
4792           or globs.
4793
4794       notes.rewriteMode
4795           When copying notes during a rewrite (see the
4796           "notes.rewrite.<command>" option), determines what to do if the
4797           target commit already has a note. Must be one of overwrite,
4798           concatenate, cat_sort_uniq, or ignore. Defaults to concatenate.
4799
4800           This setting can be overridden with the GIT_NOTES_REWRITE_MODE
4801           environment variable.
4802
4803       notes.rewriteRef
4804           When copying notes during a rewrite, specifies the (fully
4805           qualified) ref whose notes should be copied. May be a glob, in
4806           which case notes in all matching refs will be copied. You may also
4807           specify this configuration several times.
4808
4809           Does not have a default value; you must configure this variable to
4810           enable note rewriting. Set it to refs/notes/commits to enable
4811           rewriting for the default commit notes.
4812
4813           Can be overridden with the GIT_NOTES_REWRITE_REF environment
4814           variable. See notes.rewrite.<command> above for a further
4815           description of its format.
4816
4817       pack.window
4818           The size of the window used by git-pack-objects(1) when no window
4819           size is given on the command line. Defaults to 10.
4820
4821       pack.depth
4822           The maximum delta depth used by git-pack-objects(1) when no maximum
4823           depth is given on the command line. Defaults to 50. Maximum value
4824           is 4095.
4825
4826       pack.windowMemory
4827           The maximum size of memory that is consumed by each thread in git-
4828           pack-objects(1) for pack window memory when no limit is given on
4829           the command line. The value can be suffixed with "k", "m", or "g".
4830           When left unconfigured (or set explicitly to 0), there will be no
4831           limit.
4832
4833       pack.compression
4834           An integer -1..9, indicating the compression level for objects in a
4835           pack file. -1 is the zlib default. 0 means no compression, and 1..9
4836           are various speed/size tradeoffs, 9 being slowest. If not set,
4837           defaults to core.compression. If that is not set, defaults to -1,
4838           the zlib default, which is "a default compromise between speed and
4839           compression (currently equivalent to level 6)."
4840
4841           Note that changing the compression level will not automatically
4842           recompress all existing objects. You can force recompression by
4843           passing the -F option to git-repack(1).
4844
4845       pack.allowPackReuse
4846           When true, and when reachability bitmaps are enabled, pack-objects
4847           will try to send parts of the bitmapped packfile verbatim. This can
4848           reduce memory and CPU usage to serve fetches, but might result in
4849           sending a slightly larger pack. Defaults to true.
4850
4851       pack.island
4852           An extended regular expression configuring a set of delta islands.
4853           See "DELTA ISLANDS" in git-pack-objects(1) for details.
4854
4855       pack.islandCore
4856           Specify an island name which gets to have its objects be packed
4857           first. This creates a kind of pseudo-pack at the front of one pack,
4858           so that the objects from the specified island are hopefully faster
4859           to copy into any pack that should be served to a user requesting
4860           these objects. In practice this means that the island specified
4861           should likely correspond to what is the most commonly cloned in the
4862           repo. See also "DELTA ISLANDS" in git-pack-objects(1).
4863
4864       pack.deltaCacheSize
4865           The maximum memory in bytes used for caching deltas in git-pack-
4866           objects(1) before writing them out to a pack. This cache is used to
4867           speed up the writing object phase by not having to recompute the
4868           final delta result once the best match for all objects is found.
4869           Repacking large repositories on machines which are tight with
4870           memory might be badly impacted by this though, especially if this
4871           cache pushes the system into swapping. A value of 0 means no limit.
4872           The smallest size of 1 byte may be used to virtually disable this
4873           cache. Defaults to 256 MiB.
4874
4875       pack.deltaCacheLimit
4876           The maximum size of a delta, that is cached in git-pack-objects(1).
4877           This cache is used to speed up the writing object phase by not
4878           having to recompute the final delta result once the best match for
4879           all objects is found. Defaults to 1000. Maximum value is 65535.
4880
4881       pack.threads
4882           Specifies the number of threads to spawn when searching for best
4883           delta matches. This requires that git-pack-objects(1) be compiled
4884           with pthreads otherwise this option is ignored with a warning. This
4885           is meant to reduce packing time on multiprocessor machines. The
4886           required amount of memory for the delta search window is however
4887           multiplied by the number of threads. Specifying 0 will cause Git to
4888           auto-detect the number of CPUs and set the number of threads
4889           accordingly.
4890
4891       pack.indexVersion
4892           Specify the default pack index version. Valid values are 1 for
4893           legacy pack index used by Git versions prior to 1.5.2, and 2 for
4894           the new pack index with capabilities for packs larger than 4 GB as
4895           well as proper protection against the repacking of corrupted packs.
4896           Version 2 is the default. Note that version 2 is enforced and this
4897           config option is ignored whenever the corresponding pack is larger
4898           than 2 GB.
4899
4900           If you have an old Git that does not understand the version 2 *.idx
4901           file, cloning or fetching over a non-native protocol (e.g. "http")
4902           that will copy both *.pack file and corresponding *.idx file from
4903           the other side may give you a repository that cannot be accessed
4904           with your older version of Git. If the *.pack file is smaller than
4905           2 GB, however, you can use git-index-pack(1) on the *.pack file to
4906           regenerate the *.idx file.
4907
4908       pack.packSizeLimit
4909           The maximum size of a pack. This setting only affects packing to a
4910           file when repacking, i.e. the git:// protocol is unaffected. It can
4911           be overridden by the --max-pack-size option of git-repack(1).
4912           Reaching this limit results in the creation of multiple packfiles.
4913
4914           Note that this option is rarely useful, and may result in a larger
4915           total on-disk size (because Git will not store deltas between
4916           packs) and worse runtime performance (object lookup within multiple
4917           packs is slower than a single pack, and optimizations like
4918           reachability bitmaps cannot cope with multiple packs).
4919
4920           If you need to actively run Git using smaller packfiles (e.g.,
4921           because your filesystem does not support large files), this option
4922           may help. But if your goal is to transmit a packfile over a medium
4923           that supports limited sizes (e.g., removable media that cannot
4924           store the whole repository), you are likely better off creating a
4925           single large packfile and splitting it using a generic multi-volume
4926           archive tool (e.g., Unix split).
4927
4928           The minimum size allowed is limited to 1 MiB. The default is
4929           unlimited. Common unit suffixes of k, m, or g are supported.
4930
4931       pack.useBitmaps
4932           When true, git will use pack bitmaps (if available) when packing to
4933           stdout (e.g., during the server side of a fetch). Defaults to true.
4934           You should not generally need to turn this off unless you are
4935           debugging pack bitmaps.
4936
4937       pack.useBitmapBoundaryTraversal
4938           When true, Git will use an experimental algorithm for computing
4939           reachability queries with bitmaps. Instead of building up complete
4940           bitmaps for all of the negated tips and then OR-ing them together,
4941           consider negated tips with existing bitmaps as additive (i.e.
4942           OR-ing them into the result if they exist, ignoring them
4943           otherwise), and build up a bitmap at the boundary instead.
4944
4945           When using this algorithm, Git may include too many objects as a
4946           result of not opening up trees belonging to certain UNINTERESTING
4947           commits. This inexactness matches the non-bitmap traversal
4948           algorithm.
4949
4950           In many cases, this can provide a speed-up over the exact
4951           algorithm, particularly when there is poor bitmap coverage of the
4952           negated side of the query.
4953
4954       pack.useSparse
4955           When true, git will default to using the --sparse option in git
4956           pack-objects when the --revs option is present. This algorithm only
4957           walks trees that appear in paths that introduce new objects. This
4958           can have significant performance benefits when computing a pack to
4959           send a small change. However, it is possible that extra objects are
4960           added to the pack-file if the included commits contain certain
4961           types of direct renames. Default is true.
4962
4963       pack.preferBitmapTips
4964           When selecting which commits will receive bitmaps, prefer a commit
4965           at the tip of any reference that is a suffix of any value of this
4966           configuration over any other commits in the "selection window".
4967
4968           Note that setting this configuration to refs/foo does not mean that
4969           the commits at the tips of refs/foo/bar and refs/foo/baz will
4970           necessarily be selected. This is because commits are selected for
4971           bitmaps from within a series of windows of variable length.
4972
4973           If a commit at the tip of any reference which is a suffix of any
4974           value of this configuration is seen in a window, it is immediately
4975           given preference over any other commit in that window.
4976
4977       pack.writeBitmaps (deprecated)
4978           This is a deprecated synonym for repack.writeBitmaps.
4979
4980       pack.writeBitmapHashCache
4981           When true, git will include a "hash cache" section in the bitmap
4982           index (if one is written). This cache can be used to feed git’s
4983           delta heuristics, potentially leading to better deltas between
4984           bitmapped and non-bitmapped objects (e.g., when serving a fetch
4985           between an older, bitmapped pack and objects that have been pushed
4986           since the last gc). The downside is that it consumes 4 bytes per
4987           object of disk space. Defaults to true.
4988
4989           When writing a multi-pack reachability bitmap, no new namehashes
4990           are computed; instead, any namehashes stored in an existing bitmap
4991           are permuted into their appropriate location when writing a new
4992           bitmap.
4993
4994       pack.writeBitmapLookupTable
4995           When true, Git will include a "lookup table" section in the bitmap
4996           index (if one is written). This table is used to defer loading
4997           individual bitmaps as late as possible. This can be beneficial in
4998           repositories that have relatively large bitmap indexes. Defaults to
4999           false.
5000
5001       pack.readReverseIndex
5002           When true, git will read any .rev file(s) that may be available
5003           (see: gitformat-pack(5)). When false, the reverse index will be
5004           generated from scratch and stored in memory. Defaults to true.
5005
5006       pack.writeReverseIndex
5007           When true, git will write a corresponding .rev file (see:
5008           gitformat-pack(5)) for each new packfile that it writes in all
5009           places except for git-fast-import(1) and in the bulk checkin
5010           mechanism. Defaults to true.
5011
5012       pager.<cmd>
5013           If the value is boolean, turns on or off pagination of the output
5014           of a particular Git subcommand when writing to a tty. Otherwise,
5015           turns on pagination for the subcommand using the pager specified by
5016           the value of pager.<cmd>. If --paginate or --no-pager is specified
5017           on the command line, it takes precedence over this option. To
5018           disable pagination for all commands, set core.pager or GIT_PAGER to
5019           cat.
5020
5021       pretty.<name>
5022           Alias for a --pretty= format string, as specified in git-log(1).
5023           Any aliases defined here can be used just as the built-in pretty
5024           formats could. For example, running git config pretty.changelog
5025           "format:* %H %s" would cause the invocation git log
5026           --pretty=changelog to be equivalent to running git log
5027           "--pretty=format:* %H %s". Note that an alias with the same name as
5028           a built-in format will be silently ignored.
5029
5030       protocol.allow
5031           If set, provide a user defined default policy for all protocols
5032           which don’t explicitly have a policy (protocol.<name>.allow). By
5033           default, if unset, known-safe protocols (http, https, git, ssh)
5034           have a default policy of always, known-dangerous protocols (ext)
5035           have a default policy of never, and all other protocols (including
5036           file) have a default policy of user. Supported policies:
5037
5038always - protocol is always able to be used.
5039
5040never - protocol is never able to be used.
5041
5042user - protocol is only able to be used when
5043               GIT_PROTOCOL_FROM_USER is either unset or has a value of 1.
5044               This policy should be used when you want a protocol to be
5045               directly usable by the user but don’t want it used by commands
5046               which execute clone/fetch/push commands without user input,
5047               e.g. recursive submodule initialization.
5048
5049       protocol.<name>.allow
5050           Set a policy to be used by protocol <name> with clone/fetch/push
5051           commands. See protocol.allow above for the available policies.
5052
5053           The protocol names currently used by git are:
5054
5055file: any local file-based path (including file:// URLs, or
5056               local paths)
5057
5058git: the anonymous git protocol over a direct TCP connection
5059               (or proxy, if configured)
5060
5061ssh: git over ssh (including host:path syntax, ssh://, etc).
5062
5063http: git over http, both "smart http" and "dumb http". Note
5064               that this does not include https; if you want to configure
5065               both, you must do so individually.
5066
5067           •   any external helpers are named by their protocol (e.g., use hg
5068               to allow the git-remote-hg helper)
5069
5070       protocol.version
5071           If set, clients will attempt to communicate with a server using the
5072           specified protocol version. If the server does not support it,
5073           communication falls back to version 0. If unset, the default is 2.
5074           Supported versions:
5075
50760 - the original wire protocol.
5077
50781 - the original wire protocol with the addition of a version
5079               string in the initial response from the server.
5080
50812 - Wire protocol version 2, see gitprotocol-v2(5).
5082
5083       pull.ff
5084           By default, Git does not create an extra merge commit when merging
5085           a commit that is a descendant of the current commit. Instead, the
5086           tip of the current branch is fast-forwarded. When set to false,
5087           this variable tells Git to create an extra merge commit in such a
5088           case (equivalent to giving the --no-ff option from the command
5089           line). When set to only, only such fast-forward merges are allowed
5090           (equivalent to giving the --ff-only option from the command line).
5091           This setting overrides merge.ff when pulling.
5092
5093       pull.rebase
5094           When true, rebase branches on top of the fetched branch, instead of
5095           merging the default branch from the default remote when "git pull"
5096           is run. See "branch.<name>.rebase" for setting this on a per-branch
5097           basis.
5098
5099           When merges (or just m), pass the --rebase-merges option to git
5100           rebase so that the local merge commits are included in the rebase
5101           (see git-rebase(1) for details).
5102
5103           When the value is interactive (or just i), the rebase is run in
5104           interactive mode.
5105
5106           NOTE: this is a possibly dangerous operation; do not use it unless
5107           you understand the implications (see git-rebase(1) for details).
5108
5109       pull.octopus
5110           The default merge strategy to use when pulling multiple branches at
5111           once.
5112
5113       pull.twohead
5114           The default merge strategy to use when pulling a single branch.
5115
5116       push.autoSetupRemote
5117           If set to "true" assume --set-upstream on default push when no
5118           upstream tracking exists for the current branch; this option takes
5119           effect with push.default options simple, upstream, and current. It
5120           is useful if by default you want new branches to be pushed to the
5121           default remote (like the behavior of push.default=current) and you
5122           also want the upstream tracking to be set. Workflows most likely to
5123           benefit from this option are simple central workflows where all
5124           branches are expected to have the same name on the remote.
5125
5126       push.default
5127           Defines the action git push should take if no refspec is given
5128           (whether from the command-line, config, or elsewhere). Different
5129           values are well-suited for specific workflows; for instance, in a
5130           purely central workflow (i.e. the fetch source is equal to the push
5131           destination), upstream is probably what you want. Possible values
5132           are:
5133
5134nothing - do not push anything (error out) unless a refspec is
5135               given. This is primarily meant for people who want to avoid
5136               mistakes by always being explicit.
5137
5138current - push the current branch to update a branch with the
5139               same name on the receiving end. Works in both central and
5140               non-central workflows.
5141
5142upstream - push the current branch back to the branch whose
5143               changes are usually integrated into the current branch (which
5144               is called @{upstream}). This mode only makes sense if you are
5145               pushing to the same repository you would normally pull from
5146               (i.e. central workflow).
5147
5148tracking - This is a deprecated synonym for upstream.
5149
5150simple - push the current branch with the same name on the
5151               remote.
5152
5153               If you are working on a centralized workflow (pushing to the
5154               same repository you pull from, which is typically origin), then
5155               you need to configure an upstream branch with the same name.
5156
5157               This mode is the default since Git 2.0, and is the safest
5158               option suited for beginners.
5159
5160matching - push all branches having the same name on both ends.
5161               This makes the repository you are pushing to remember the set
5162               of branches that will be pushed out (e.g. if you always push
5163               maint and master there and no other branches, the repository
5164               you push to will have these two branches, and your local maint
5165               and master will be pushed there).
5166
5167               To use this mode effectively, you have to make sure all the
5168               branches you would push out are ready to be pushed out before
5169               running git push, as the whole point of this mode is to allow
5170               you to push all of the branches in one go. If you usually
5171               finish work on only one branch and push out the result, while
5172               other branches are unfinished, this mode is not for you. Also
5173               this mode is not suitable for pushing into a shared central
5174               repository, as other people may add new branches there, or
5175               update the tip of existing branches outside your control.
5176
5177               This used to be the default, but not since Git 2.0 (simple is
5178               the new default).
5179
5180       push.followTags
5181           If set to true, enable --follow-tags option by default. You may
5182           override this configuration at time of push by specifying
5183           --no-follow-tags.
5184
5185       push.gpgSign
5186           May be set to a boolean value, or the string if-asked. A true value
5187           causes all pushes to be GPG signed, as if --signed is passed to
5188           git-push(1). The string if-asked causes pushes to be signed if the
5189           server supports it, as if --signed=if-asked is passed to git push.
5190           A false value may override a value from a lower-priority config
5191           file. An explicit command-line flag always overrides this config
5192           option.
5193
5194       push.pushOption
5195           When no --push-option=<option> argument is given from the command
5196           line, git push behaves as if each <value> of this variable is given
5197           as --push-option=<value>.
5198
5199           This is a multi-valued variable, and an empty value can be used in
5200           a higher priority configuration file (e.g.  .git/config in a
5201           repository) to clear the values inherited from a lower priority
5202           configuration files (e.g.  $HOME/.gitconfig).
5203
5204               Example:
5205
5206               /etc/gitconfig
5207                 push.pushoption = a
5208                 push.pushoption = b

5211                 push.pushoption = c
5212
5213               repo/.git/config
5214                 push.pushoption =
5215                 push.pushoption = b
5216
5217               This will result in only b (a and c are cleared).
5218
5219       push.recurseSubmodules
5220           May be "check", "on-demand", "only", or "no", with the same
5221           behavior as that of "push --recurse-submodules". If not set, no is
5222           used by default, unless submodule.recurse is set (in which case a
5223           true value means on-demand).
5224
5225       push.useForceIfIncludes
5226           If set to "true", it is equivalent to specifying
5227           --force-if-includes as an option to git-push(1) in the command
5228           line. Adding --no-force-if-includes at the time of push overrides
5229           this configuration setting.
5230
5231       push.negotiate
5232           If set to "true", attempt to reduce the size of the packfile sent
5233           by rounds of negotiation in which the client and the server attempt
5234           to find commits in common. If "false", Git will rely solely on the
5235           server’s ref advertisement to find commits in common.
5236
5237       push.useBitmaps
5238           If set to "false", disable use of bitmaps for "git push" even if
5239           pack.useBitmaps is "true", without preventing other git operations
5240           from using bitmaps. Default is true.
5241
5242       rebase.backend
5243           Default backend to use for rebasing. Possible choices are apply or
5244           merge. In the future, if the merge backend gains all remaining
5245           capabilities of the apply backend, this setting may become unused.
5246
5247       rebase.stat
5248           Whether to show a diffstat of what changed upstream since the last
5249           rebase. False by default.
5250
5251       rebase.autoSquash
5252           If set to true enable --autosquash option by default.
5253
5254       rebase.autoStash
5255           When set to true, automatically create a temporary stash entry
5256           before the operation begins, and apply it after the operation ends.
5257           This means that you can run rebase on a dirty worktree. However,
5258           use with care: the final stash application after a successful
5259           rebase might result in non-trivial conflicts. This option can be
5260           overridden by the --no-autostash and --autostash options of git-
5261           rebase(1). Defaults to false.
5262
5263       rebase.updateRefs
5264           If set to true enable --update-refs option by default.
5265
5266       rebase.missingCommitsCheck
5267           If set to "warn", git rebase -i will print a warning if some
5268           commits are removed (e.g. a line was deleted), however the rebase
5269           will still proceed. If set to "error", it will print the previous
5270           warning and stop the rebase, git rebase --edit-todo can then be
5271           used to correct the error. If set to "ignore", no checking is done.
5272           To drop a commit without warning or error, use the drop command in
5273           the todo list. Defaults to "ignore".
5274
5275       rebase.instructionFormat
5276           A format string, as specified in git-log(1), to be used for the
5277           todo list during an interactive rebase. The format will
5278           automatically have the long commit hash prepended to the format.
5279
5280       rebase.abbreviateCommands
5281           If set to true, git rebase will use abbreviated command names in
5282           the todo list resulting in something like this:
5283
5284                       p deadbee The oneline of the commit
5285                       p fa1afe1 The oneline of the next commit
5286                       ...
5287
5288           instead of:
5289
5290                       pick deadbee The oneline of the commit
5291                       pick fa1afe1 The oneline of the next commit
5292                       ...
5293
5294           Defaults to false.
5295
5296       rebase.rescheduleFailedExec
5297           Automatically reschedule exec commands that failed. This only makes
5298           sense in interactive mode (or when an --exec option was provided).
5299           This is the same as specifying the --reschedule-failed-exec option.
5300
5301       rebase.forkPoint
5302           If set to false set --no-fork-point option by default.
5303
5304       rebase.rebaseMerges
5305           Whether and how to set the --rebase-merges option by default. Can
5306           be rebase-cousins, no-rebase-cousins, or a boolean. Setting to true
5307           or to no-rebase-cousins is equivalent to
5308           --rebase-merges=no-rebase-cousins, setting to rebase-cousins is
5309           equivalent to --rebase-merges=rebase-cousins, and setting to false
5310           is equivalent to --no-rebase-merges. Passing --rebase-merges on the
5311           command line, with or without an argument, overrides any
5312           rebase.rebaseMerges configuration.
5313
5314       rebase.maxLabelLength
5315           When generating label names from commit subjects, truncate the
5316           names to this length. By default, the names are truncated to a
5317           little less than NAME_MAX (to allow e.g.  .lock files to be written
5318           for the corresponding loose refs).
5319
5320       receive.advertiseAtomic
5321           By default, git-receive-pack will advertise the atomic push
5322           capability to its clients. If you don’t want to advertise this
5323           capability, set this variable to false.
5324
5325       receive.advertisePushOptions
5326           When set to true, git-receive-pack will advertise the push options
5327           capability to its clients. False by default.
5328
5329       receive.autogc
5330           By default, git-receive-pack will run "git-gc --auto" after
5331           receiving data from git-push and updating refs. You can stop it by
5332           setting this variable to false.
5333
5334       receive.certNonceSeed
5335           By setting this variable to a string, git receive-pack will accept
5336           a git push --signed and verify it by using a "nonce" protected by
5337           HMAC using this string as a secret key.
5338
5339       receive.certNonceSlop
5340           When a git push --signed sends a push certificate with a "nonce"
5341           that was issued by a receive-pack serving the same repository
5342           within this many seconds, export the "nonce" found in the
5343           certificate to GIT_PUSH_CERT_NONCE to the hooks (instead of what
5344           the receive-pack asked the sending side to include). This may allow
5345           writing checks in pre-receive and post-receive a bit easier.
5346           Instead of checking GIT_PUSH_CERT_NONCE_SLOP environment variable
5347           that records by how many seconds the nonce is stale to decide if
5348           they want to accept the certificate, they only can check
5349           GIT_PUSH_CERT_NONCE_STATUS is OK.
5350
5351       receive.fsckObjects
5352           If it is set to true, git-receive-pack will check all received
5353           objects. See transfer.fsckObjects for what’s checked. Defaults to
5354           false. If not set, the value of transfer.fsckObjects is used
5355           instead.
5356
5357       receive.fsck.<msg-id>
5358           Acts like fsck.<msg-id>, but is used by git-receive-pack(1) instead
5359           of git-fsck(1). See the fsck.<msg-id> documentation for details.
5360
5361       receive.fsck.skipList
5362           Acts like fsck.skipList, but is used by git-receive-pack(1) instead
5363           of git-fsck(1). See the fsck.skipList documentation for details.
5364
5365       receive.keepAlive
5366           After receiving the pack from the client, receive-pack may produce
5367           no output (if --quiet was specified) while processing the pack,
5368           causing some networks to drop the TCP connection. With this option
5369           set, if receive-pack does not transmit any data in this phase for
5370           receive.keepAlive seconds, it will send a short keepalive packet.
5371           The default is 5 seconds; set to 0 to disable keepalives entirely.
5372
5373       receive.unpackLimit
5374           If the number of objects received in a push is below this limit
5375           then the objects will be unpacked into loose object files. However
5376           if the number of received objects equals or exceeds this limit then
5377           the received pack will be stored as a pack, after adding any
5378           missing delta bases. Storing the pack from a push can make the push
5379           operation complete faster, especially on slow filesystems. If not
5380           set, the value of transfer.unpackLimit is used instead.
5381
5382       receive.maxInputSize
5383           If the size of the incoming pack stream is larger than this limit,
5384           then git-receive-pack will error out, instead of accepting the pack
5385           file. If not set or set to 0, then the size is unlimited.
5386
5387       receive.denyDeletes
5388           If set to true, git-receive-pack will deny a ref update that
5389           deletes the ref. Use this to prevent such a ref deletion via a
5390           push.
5391
5392       receive.denyDeleteCurrent
5393           If set to true, git-receive-pack will deny a ref update that
5394           deletes the currently checked out branch of a non-bare repository.
5395
5396       receive.denyCurrentBranch
5397           If set to true or "refuse", git-receive-pack will deny a ref update
5398           to the currently checked out branch of a non-bare repository. Such
5399           a push is potentially dangerous because it brings the HEAD out of
5400           sync with the index and working tree. If set to "warn", print a
5401           warning of such a push to stderr, but allow the push to proceed. If
5402           set to false or "ignore", allow such pushes with no message.
5403           Defaults to "refuse".
5404
5405           Another option is "updateInstead" which will update the working
5406           tree if pushing into the current branch. This option is intended
5407           for synchronizing working directories when one side is not easily
5408           accessible via interactive ssh (e.g. a live web site, hence the
5409           requirement that the working directory be clean). This mode also
5410           comes in handy when developing inside a VM to test and fix code on
5411           different Operating Systems.
5412
5413           By default, "updateInstead" will refuse the push if the working
5414           tree or the index have any difference from the HEAD, but the
5415           push-to-checkout hook can be used to customize this. See
5416           githooks(5).
5417
5418       receive.denyNonFastForwards
5419           If set to true, git-receive-pack will deny a ref update which is
5420           not a fast-forward. Use this to prevent such an update via a push,
5421           even if that push is forced. This configuration variable is set
5422           when initializing a shared repository.
5423
5424       receive.hideRefs
5425           This variable is the same as transfer.hideRefs, but applies only to
5426           receive-pack (and so affects pushes, but not fetches). An attempt
5427           to update or delete a hidden ref by git push is rejected.
5428
5429       receive.procReceiveRefs
5430           This is a multi-valued variable that defines reference prefixes to
5431           match the commands in receive-pack. Commands matching the prefixes
5432           will be executed by an external hook "proc-receive", instead of the
5433           internal execute_commands function. If this variable is not
5434           defined, the "proc-receive" hook will never be used, and all
5435           commands will be executed by the internal execute_commands
5436           function.
5437
5438           For example, if this variable is set to "refs/for", pushing to
5439           reference such as "refs/for/master" will not create or update a
5440           reference named "refs/for/master", but may create or update a pull
5441           request directly by running the hook "proc-receive".
5442
5443           Optional modifiers can be provided in the beginning of the value to
5444           filter commands for specific actions: create (a), modify (m),
5445           delete (d). A !  can be included in the modifiers to negate the
5446           reference prefix entry. E.g.:
5447
5448               git config --system --add receive.procReceiveRefs ad:refs/heads
5449               git config --system --add receive.procReceiveRefs !:refs/heads
5450
5451       receive.updateServerInfo
5452           If set to true, git-receive-pack will run git-update-server-info
5453           after receiving data from git-push and updating refs.
5454
5455       receive.shallowUpdate
5456           If set to true, .git/shallow can be updated when new refs require
5457           new shallow roots. Otherwise those refs are rejected.
5458
5459       remote.pushDefault
5460           The remote to push to by default. Overrides branch.<name>.remote
5461           for all branches, and is overridden by branch.<name>.pushRemote for
5462           specific branches.
5463
5464       remote.<name>.url
5465           The URL of a remote repository. See git-fetch(1) or git-push(1).
5466
5467       remote.<name>.pushurl
5468           The push URL of a remote repository. See git-push(1).
5469
5470       remote.<name>.proxy
5471           For remotes that require curl (http, https and ftp), the URL to the
5472           proxy to use for that remote. Set to the empty string to disable
5473           proxying for that remote.
5474
5475       remote.<name>.proxyAuthMethod
5476           For remotes that require curl (http, https and ftp), the method to
5477           use for authenticating against the proxy in use (probably set in
5478           remote.<name>.proxy). See http.proxyAuthMethod.
5479
5480       remote.<name>.fetch
5481           The default set of "refspec" for git-fetch(1). See git-fetch(1).
5482
5483       remote.<name>.push
5484           The default set of "refspec" for git-push(1). See git-push(1).
5485
5486       remote.<name>.mirror
5487           If true, pushing to this remote will automatically behave as if the
5488           --mirror option was given on the command line.
5489
5490       remote.<name>.skipDefaultUpdate
5491           If true, this remote will be skipped by default when updating using
5492           git-fetch(1) or the update subcommand of git-remote(1).
5493
5494       remote.<name>.skipFetchAll
5495           If true, this remote will be skipped by default when updating using
5496           git-fetch(1) or the update subcommand of git-remote(1).
5497
5498       remote.<name>.receivepack
5499           The default program to execute on the remote side when pushing. See
5500           option --receive-pack of git-push(1).
5501
5502       remote.<name>.uploadpack
5503           The default program to execute on the remote side when fetching.
5504           See option --upload-pack of git-fetch-pack(1).
5505
5506       remote.<name>.tagOpt
5507           Setting this value to --no-tags disables automatic tag following
5508           when fetching from remote <name>. Setting it to --tags will fetch
5509           every tag from remote <name>, even if they are not reachable from
5510           remote branch heads. Passing these flags directly to git-fetch(1)
5511           can override this setting. See options --tags and --no-tags of git-
5512           fetch(1).
5513
5514       remote.<name>.vcs
5515           Setting this to a value <vcs> will cause Git to interact with the
5516           remote with the git-remote-<vcs> helper.
5517
5518       remote.<name>.prune
5519           When set to true, fetching from this remote by default will also
5520           remove any remote-tracking references that no longer exist on the
5521           remote (as if the --prune option was given on the command line).
5522           Overrides fetch.prune settings, if any.
5523
5524       remote.<name>.pruneTags
5525           When set to true, fetching from this remote by default will also
5526           remove any local tags that no longer exist on the remote if pruning
5527           is activated in general via remote.<name>.prune, fetch.prune or
5528           --prune. Overrides fetch.pruneTags settings, if any.
5529
5530           See also remote.<name>.prune and the PRUNING section of git-
5531           fetch(1).
5532
5533       remote.<name>.promisor
5534           When set to true, this remote will be used to fetch promisor
5535           objects.
5536
5537       remote.<name>.partialclonefilter
5538           The filter that will be applied when fetching from this promisor
5539           remote. Changing or clearing this value will only affect fetches
5540           for new commits. To fetch associated objects for commits already
5541           present in the local object database, use the --refetch option of
5542           git-fetch(1).
5543
5544       remotes.<group>
5545           The list of remotes which are fetched by "git remote update
5546           <group>". See git-remote(1).
5547
5548       repack.useDeltaBaseOffset
5549           By default, git-repack(1) creates packs that use delta-base offset.
5550           If you need to share your repository with Git older than version
5551           1.4.4, either directly or via a dumb protocol such as http, then
5552           you need to set this option to "false" and repack. Access from old
5553           Git versions over the native protocol are unaffected by this
5554           option.
5555
5556       repack.packKeptObjects
5557           If set to true, makes git repack act as if --pack-kept-objects was
5558           passed. See git-repack(1) for details. Defaults to false normally,
5559           but true if a bitmap index is being written (either via
5560           --write-bitmap-index or repack.writeBitmaps).
5561
5562       repack.useDeltaIslands
5563           If set to true, makes git repack act as if --delta-islands was
5564           passed. Defaults to false.
5565
5566       repack.writeBitmaps
5567           When true, git will write a bitmap index when packing all objects
5568           to disk (e.g., when git repack -a is run). This index can speed up
5569           the "counting objects" phase of subsequent packs created for clones
5570           and fetches, at the cost of some disk space and extra time spent on
5571           the initial repack. This has no effect if multiple packfiles are
5572           created. Defaults to true on bare repos, false otherwise.
5573
5574       repack.updateServerInfo
5575           If set to false, git-repack(1) will not run git-update-server-
5576           info(1). Defaults to true. Can be overridden when true by the -n
5577           option of git-repack(1).
5578
5579       repack.cruftWindow, repack.cruftWindowMemory, repack.cruftDepth,
5580       repack.cruftThreads
5581           Parameters used by git-pack-objects(1) when generating a cruft pack
5582           and the respective parameters are not given over the command line.
5583           See similarly named pack.*  configuration variables for defaults
5584           and meaning.
5585
5586       rerere.autoUpdate
5587           When set to true, git-rerere updates the index with the resulting
5588           contents after it cleanly resolves conflicts using previously
5589           recorded resolutions. Defaults to false.
5590
5591       rerere.enabled
5592           Activate recording of resolved conflicts, so that identical
5593           conflict hunks can be resolved automatically, should they be
5594           encountered again. By default, git-rerere(1) is enabled if there is
5595           an rr-cache directory under the $GIT_DIR, e.g. if "rerere" was
5596           previously used in the repository.
5597
5598       revert.reference
5599           Setting this variable to true makes git revert behave as if the
5600           --reference option is given.
5601
5602       safe.bareRepository
5603           Specifies which bare repositories Git will work with. The currently
5604           supported values are:
5605
5606all: Git works with all bare repositories. This is the default.
5607
5608explicit: Git only works with bare repositories specified via
5609               the top-level --git-dir command-line option, or the GIT_DIR
5610               environment variable (see git(1)).
5611
5612               If you do not use bare repositories in your workflow, then it
5613               may be beneficial to set safe.bareRepository to explicit in
5614               your global config. This will protect you from attacks that
5615               involve cloning a repository that contains a bare repository
5616               and running a Git command within that directory.
5617
5618               This config setting is only respected in protected
5619               configuration (see the section called “SCOPES”). This prevents
5620               untrusted repositories from tampering with this value.
5621
5622       safe.directory
5623           These config entries specify Git-tracked directories that are
5624           considered safe even if they are owned by someone other than the
5625           current user. By default, Git will refuse to even parse a Git
5626           config of a repository owned by someone else, let alone run its
5627           hooks, and this config setting allows users to specify exceptions,
5628           e.g. for intentionally shared repositories (see the --shared option
5629           in git-init(1)).
5630
5631           This is a multi-valued setting, i.e. you can add more than one
5632           directory via git config --add. To reset the list of safe
5633           directories (e.g. to override any such directories specified in the
5634           system config), add a safe.directory entry with an empty value.
5635
5636           This config setting is only respected in protected configuration
5637           (see the section called “SCOPES”). This prevents untrusted
5638           repositories from tampering with this value.
5639
5640           The value of this setting is interpolated, i.e.  ~/<path> expands
5641           to a path relative to the home directory and %(prefix)/<path>
5642           expands to a path relative to Git’s (runtime) prefix.
5643
5644           To completely opt-out of this security check, set safe.directory to
5645           the string *. This will allow all repositories to be treated as if
5646           their directory was listed in the safe.directory list. If
5647           safe.directory=* is set in system config and you want to re-enable
5648           this protection, then initialize your list with an empty value
5649           before listing the repositories that you deem safe.
5650
5651           As explained, Git only allows you to access repositories owned by
5652           yourself, i.e. the user who is running Git, by default. When Git is
5653           running as root in a non Windows platform that provides sudo,
5654           however, git checks the SUDO_UID environment variable that sudo
5655           creates and will allow access to the uid recorded as its value in
5656           addition to the id from root. This is to make it easy to perform a
5657           common sequence during installation "make && sudo make install". A
5658           git process running under sudo runs as root but the sudo command
5659           exports the environment variable to record which id the original
5660           user has. If that is not what you would prefer and want git to only
5661           trust repositories that are owned by root instead, then you can
5662           remove the SUDO_UID variable from root’s environment before
5663           invoking git.
5664
5665       sendemail.identity
5666           A configuration identity. When given, causes values in the
5667           sendemail.<identity> subsection to take precedence over values in
5668           the sendemail section. The default identity is the value of
5669           sendemail.identity.
5670
5671       sendemail.smtpEncryption
5672           See git-send-email(1) for description. Note that this setting is
5673           not subject to the identity mechanism.
5674
5675       sendemail.smtpsslcertpath
5676           Path to ca-certificates (either a directory or a single file). Set
5677           it to an empty string to disable certificate verification.
5678
5679       sendemail.<identity>.*
5680           Identity-specific versions of the sendemail.*  parameters found
5681           below, taking precedence over those when this identity is selected,
5682           through either the command-line or sendemail.identity.
5683
5684       sendemail.multiEdit
5685           If true (default), a single editor instance will be spawned to edit
5686           files you have to edit (patches when --annotate is used, and the
5687           summary when --compose is used). If false, files will be edited one
5688           after the other, spawning a new editor each time.
5689
5690       sendemail.confirm
5691           Sets the default for whether to confirm before sending. Must be one
5692           of always, never, cc, compose, or auto. See --confirm in the git-
5693           send-email(1) documentation for the meaning of these values.
5694
5695       sendemail.aliasesFile
5696           To avoid typing long email addresses, point this to one or more
5697           email aliases files. You must also supply sendemail.aliasFileType.
5698
5699       sendemail.aliasFileType
5700           Format of the file(s) specified in sendemail.aliasesFile. Must be
5701           one of mutt, mailrc, pine, elm, gnus, or sendmail.
5702
5703           What an alias file in each format looks like can be found in the
5704           documentation of the email program of the same name. The
5705           differences and limitations from the standard formats are described
5706           below:
5707
5708           sendmail
5709
5710               •   Quoted aliases and quoted addresses are not supported:
5711                   lines that contain a " symbol are ignored.
5712
5713               •   Redirection to a file (/path/name) or pipe (|command) is
5714                   not supported.
5715
5716               •   File inclusion (:include: /path/name) is not supported.
5717
5718               •   Warnings are printed on the standard error output for any
5719                   explicitly unsupported constructs, and any other lines that
5720                   are not recognized by the parser.
5721
5722       sendemail.annotate, sendemail.bcc, sendemail.cc, sendemail.ccCmd,
5723       sendemail.chainReplyTo, sendemail.envelopeSender, sendemail.from,
5724       sendemail.headerCmd, sendemail.signedoffbycc, sendemail.smtpPass,
5725       sendemail.suppresscc, sendemail.suppressFrom, sendemail.to,
5726       sendemail.tocmd, sendemail.smtpDomain, sendemail.smtpServer,
5727       sendemail.smtpServerPort, sendemail.smtpServerOption,
5728       sendemail.smtpUser, sendemail.thread, sendemail.transferEncoding,
5729       sendemail.validate, sendemail.xmailer
5730           These configuration variables all provide a default for git-send-
5731           email(1) command-line options. See its documentation for details.
5732
5733       sendemail.signedoffcc (deprecated)
5734           Deprecated alias for sendemail.signedoffbycc.
5735
5736       sendemail.smtpBatchSize
5737           Number of messages to be sent per connection, after that a relogin
5738           will happen. If the value is 0 or undefined, send all messages in
5739           one connection. See also the --batch-size option of git-send-
5740           email(1).
5741
5742       sendemail.smtpReloginDelay
5743           Seconds to wait before reconnecting to the smtp server. See also
5744           the --relogin-delay option of git-send-email(1).
5745
5746       sendemail.forbidSendmailVariables
5747           To avoid common misconfiguration mistakes, git-send-email(1) will
5748           abort with a warning if any configuration options for "sendmail"
5749           exist. Set this variable to bypass the check.
5750
5751       sequence.editor
5752           Text editor used by git rebase -i for editing the rebase
5753           instruction file. The value is meant to be interpreted by the shell
5754           when it is used. It can be overridden by the GIT_SEQUENCE_EDITOR
5755           environment variable. When not configured, the default commit
5756           message editor is used instead.
5757
5758       showBranch.default
5759           The default set of branches for git-show-branch(1). See git-show-
5760           branch(1).
5761
5762       sparse.expectFilesOutsideOfPatterns
5763           Typically with sparse checkouts, files not matching any sparsity
5764           patterns are marked with a SKIP_WORKTREE bit in the index and are
5765           missing from the working tree. Accordingly, Git will ordinarily
5766           check whether files with the SKIP_WORKTREE bit are in fact present
5767           in the working tree contrary to expectations. If Git finds any, it
5768           marks those paths as present by clearing the relevant SKIP_WORKTREE
5769           bits. This option can be used to tell Git that such
5770           present-despite-skipped files are expected and to stop checking for
5771           them.
5772
5773           The default is false, which allows Git to automatically recover
5774           from the list of files in the index and working tree falling out of
5775           sync.
5776
5777           Set this to true if you are in a setup where some external factor
5778           relieves Git of the responsibility for maintaining the consistency
5779           between the presence of working tree files and sparsity patterns.
5780           For example, if you have a Git-aware virtual file system that has a
5781           robust mechanism for keeping the working tree and the sparsity
5782           patterns up to date based on access patterns.
5783
5784           Regardless of this setting, Git does not check for
5785           present-despite-skipped files unless sparse checkout is enabled, so
5786           this config option has no effect unless core.sparseCheckout is
5787           true.
5788
5789       splitIndex.maxPercentChange
5790           When the split index feature is used, this specifies the percent of
5791           entries the split index can contain compared to the total number of
5792           entries in both the split index and the shared index before a new
5793           shared index is written. The value should be between 0 and 100. If
5794           the value is 0, then a new shared index is always written; if it is
5795           100, a new shared index is never written. By default, the value is
5796           20, so a new shared index is written if the number of entries in
5797           the split index would be greater than 20 percent of the total
5798           number of entries. See git-update-index(1).
5799
5800       splitIndex.sharedIndexExpire
5801           When the split index feature is used, shared index files that were
5802           not modified since the time this variable specifies will be removed
5803           when a new shared index file is created. The value "now" expires
5804           all entries immediately, and "never" suppresses expiration
5805           altogether. The default value is "2.weeks.ago". Note that a shared
5806           index file is considered modified (for the purpose of expiration)
5807           each time a new split-index file is either created based on it or
5808           read from it. See git-update-index(1).
5809
5810       ssh.variant
5811           By default, Git determines the command line arguments to use based
5812           on the basename of the configured SSH command (configured using the
5813           environment variable GIT_SSH or GIT_SSH_COMMAND or the config
5814           setting core.sshCommand). If the basename is unrecognized, Git will
5815           attempt to detect support of OpenSSH options by first invoking the
5816           configured SSH command with the -G (print configuration) option and
5817           will subsequently use OpenSSH options (if that is successful) or no
5818           options besides the host and remote command (if it fails).
5819
5820           The config variable ssh.variant can be set to override this
5821           detection. Valid values are ssh (to use OpenSSH options), plink,
5822           putty, tortoiseplink, simple (no options except the host and remote
5823           command). The default auto-detection can be explicitly requested
5824           using the value auto. Any other value is treated as ssh. This
5825           setting can also be overridden via the environment variable
5826           GIT_SSH_VARIANT.
5827
5828           The current command-line parameters used for each variant are as
5829           follows:
5830
5831ssh - [-p port] [-4] [-6] [-o option] [username@]host command
5832
5833simple - [username@]host command
5834
5835plink or putty - [-P port] [-4] [-6] [username@]host command
5836
5837tortoiseplink - [-P port] [-4] [-6] -batch [username@]host
5838               command
5839
5840           Except for the simple variant, command-line parameters are likely
5841           to change as git gains new features.
5842
5843       status.relativePaths
5844           By default, git-status(1) shows paths relative to the current
5845           directory. Setting this variable to false shows paths relative to
5846           the repository root (this was the default for Git prior to v1.5.4).
5847
5848       status.short
5849           Set to true to enable --short by default in git-status(1). The
5850           option --no-short takes precedence over this variable.
5851
5852       status.branch
5853           Set to true to enable --branch by default in git-status(1). The
5854           option --no-branch takes precedence over this variable.
5855
5856       status.aheadBehind
5857           Set to true to enable --ahead-behind and false to enable
5858           --no-ahead-behind by default in git-status(1) for non-porcelain
5859           status formats. Defaults to true.
5860
5861       status.displayCommentPrefix
5862           If set to true, git-status(1) will insert a comment prefix before
5863           each output line (starting with core.commentChar, i.e.  # by
5864           default). This was the behavior of git-status(1) in Git 1.8.4 and
5865           previous. Defaults to false.
5866
5867       status.renameLimit
5868           The number of files to consider when performing rename detection in
5869           git-status(1) and git-commit(1). Defaults to the value of
5870           diff.renameLimit.
5871
5872       status.renames
5873           Whether and how Git detects renames in git-status(1) and git-
5874           commit(1) . If set to "false", rename detection is disabled. If set
5875           to "true", basic rename detection is enabled. If set to "copies" or
5876           "copy", Git will detect copies, as well. Defaults to the value of
5877           diff.renames.
5878
5879       status.showStash
5880           If set to true, git-status(1) will display the number of entries
5881           currently stashed away. Defaults to false.
5882
5883       status.showUntrackedFiles
5884           By default, git-status(1) and git-commit(1) show files which are
5885           not currently tracked by Git. Directories which contain only
5886           untracked files, are shown with the directory name only. Showing
5887           untracked files means that Git needs to lstat() all the files in
5888           the whole repository, which might be slow on some systems. So, this
5889           variable controls how the commands display the untracked files.
5890           Possible values are:
5891
5892no - Show no untracked files.
5893
5894normal - Show untracked files and directories.
5895
5896all - Show also individual files in untracked directories.
5897
5898           If this variable is not specified, it defaults to normal. This
5899           variable can be overridden with the -u|--untracked-files option of
5900           git-status(1) and git-commit(1).
5901
5902       status.submoduleSummary
5903           Defaults to false. If this is set to a non-zero number or true
5904           (identical to -1 or an unlimited number), the submodule summary
5905           will be enabled and a summary of commits for modified submodules
5906           will be shown (see --summary-limit option of git-submodule(1)).
5907           Please note that the summary output command will be suppressed for
5908           all submodules when diff.ignoreSubmodules is set to all or only for
5909           those submodules where submodule.<name>.ignore=all. The only
5910           exception to that rule is that status and commit will show staged
5911           submodule changes. To also view the summary for ignored submodules
5912           you can either use the --ignore-submodules=dirty command-line
5913           option or the git submodule summary command, which shows a similar
5914           output but does not honor these settings.
5915
5916       stash.showIncludeUntracked
5917           If this is set to true, the git stash show command will show the
5918           untracked files of a stash entry. Defaults to false. See the
5919           description of the show command in git-stash(1).
5920
5921       stash.showPatch
5922           If this is set to true, the git stash show command without an
5923           option will show the stash entry in patch form. Defaults to false.
5924           See the description of the show command in git-stash(1).
5925
5926       stash.showStat
5927           If this is set to true, the git stash show command without an
5928           option will show a diffstat of the stash entry. Defaults to true.
5929           See the description of the show command in git-stash(1).
5930
5931       submodule.<name>.url
5932           The URL for a submodule. This variable is copied from the
5933           .gitmodules file to the git config via git submodule init. The user
5934           can change the configured URL before obtaining the submodule via
5935           git submodule update. If neither submodule.<name>.active nor
5936           submodule.active are set, the presence of this variable is used as
5937           a fallback to indicate whether the submodule is of interest to git
5938           commands. See git-submodule(1) and gitmodules(5) for details.
5939
5940       submodule.<name>.update
5941           The method by which a submodule is updated by git submodule update,
5942           which is the only affected command, others such as git checkout
5943           --recurse-submodules are unaffected. It exists for historical
5944           reasons, when git submodule was the only command to interact with
5945           submodules; settings like submodule.active and pull.rebase are more
5946           specific. It is populated by git submodule init from the
5947           gitmodules(5) file. See description of update command in git-
5948           submodule(1).
5949
5950       submodule.<name>.branch
5951           The remote branch name for a submodule, used by git submodule
5952           update --remote. Set this option to override the value found in the
5953           .gitmodules file. See git-submodule(1) and gitmodules(5) for
5954           details.
5955
5956       submodule.<name>.fetchRecurseSubmodules
5957           This option can be used to control recursive fetching of this
5958           submodule. It can be overridden by using the
5959           --[no-]recurse-submodules command-line option to "git fetch" and
5960           "git pull". This setting will override that from in the
5961           gitmodules(5) file.
5962
5963       submodule.<name>.ignore
5964           Defines under what circumstances "git status" and the diff family
5965           show a submodule as modified. When set to "all", it will never be
5966           considered modified (but it will nonetheless show up in the output
5967           of status and commit when it has been staged), "dirty" will ignore
5968           all changes to the submodule’s work tree and takes only differences
5969           between the HEAD of the submodule and the commit recorded in the
5970           superproject into account. "untracked" will additionally let
5971           submodules with modified tracked files in their work tree show up.
5972           Using "none" (the default when this option is not set) also shows
5973           submodules that have untracked files in their work tree as changed.
5974           This setting overrides any setting made in .gitmodules for this
5975           submodule, both settings can be overridden on the command line by
5976           using the "--ignore-submodules" option. The git submodule commands
5977           are not affected by this setting.
5978
5979       submodule.<name>.active
5980           Boolean value indicating if the submodule is of interest to git
5981           commands. This config option takes precedence over the
5982           submodule.active config option. See gitsubmodules(7) for details.
5983
5984       submodule.active
5985           A repeated field which contains a pathspec used to match against a
5986           submodule’s path to determine if the submodule is of interest to
5987           git commands. See gitsubmodules(7) for details.
5988
5989       submodule.recurse
5990           A boolean indicating if commands should enable the
5991           --recurse-submodules option by default. Defaults to false.
5992
5993           When set to true, it can be deactivated via the
5994           --no-recurse-submodules option. Note that some Git commands lacking
5995           this option may call some of the above commands affected by
5996           submodule.recurse; for instance git remote update will call git
5997           fetch but does not have a --no-recurse-submodules option. For these
5998           commands a workaround is to temporarily change the configuration
5999           value by using git -c submodule.recurse=0.
6000
6001           The following list shows the commands that accept
6002           --recurse-submodules and whether they are supported by this
6003           setting.
6004
6005checkout, fetch, grep, pull, push, read-tree, reset, restore
6006               and switch are always supported.
6007
6008clone and ls-files are not supported.
6009
6010branch is supported only if submodule.propagateBranches is
6011               enabled
6012
6013       submodule.propagateBranches
6014           [EXPERIMENTAL] A boolean that enables branching support when using
6015           --recurse-submodules or submodule.recurse=true. Enabling this will
6016           allow certain commands to accept --recurse-submodules and certain
6017           commands that already accept --recurse-submodules will now consider
6018           branches. Defaults to false.
6019
6020       submodule.fetchJobs
6021           Specifies how many submodules are fetched/cloned at the same time.
6022           A positive integer allows up to that number of submodules fetched
6023           in parallel. A value of 0 will give some reasonable default. If
6024           unset, it defaults to 1.
6025
6026       submodule.alternateLocation
6027           Specifies how the submodules obtain alternates when submodules are
6028           cloned. Possible values are no, superproject. By default no is
6029           assumed, which doesn’t add references. When the value is set to
6030           superproject the submodule to be cloned computes its alternates
6031           location relative to the superprojects alternate.
6032
6033       submodule.alternateErrorStrategy
6034           Specifies how to treat errors with the alternates for a submodule
6035           as computed via submodule.alternateLocation. Possible values are
6036           ignore, info, die. Default is die. Note that if set to ignore or
6037           info, and if there is an error with the computed alternate, the
6038           clone proceeds as if no alternate was specified.
6039
6040       tag.forceSignAnnotated
6041           A boolean to specify whether annotated tags created should be GPG
6042           signed. If --annotate is specified on the command line, it takes
6043           precedence over this option.
6044
6045       tag.sort
6046           This variable controls the sort ordering of tags when displayed by
6047           git-tag(1). Without the "--sort=<value>" option provided, the value
6048           of this variable will be used as the default.
6049
6050       tag.gpgSign
6051           A boolean to specify whether all tags should be GPG signed. Use of
6052           this option when running in an automated script can result in a
6053           large number of tags being signed. It is therefore convenient to
6054           use an agent to avoid typing your gpg passphrase several times.
6055           Note that this option doesn’t affect tag signing behavior enabled
6056           by "-u <keyid>" or "--local-user=<keyid>" options.
6057
6058       tar.umask
6059           This variable can be used to restrict the permission bits of tar
6060           archive entries. The default is 0002, which turns off the world
6061           write bit. The special value "user" indicates that the archiving
6062           user’s umask will be used instead. See umask(2) and git-archive(1).
6063
6064       Trace2 config settings are only read from the system and global config
6065       files; repository local and worktree config files and -c command line
6066       arguments are not respected.
6067
6068       trace2.normalTarget
6069           This variable controls the normal target destination. It may be
6070           overridden by the GIT_TRACE2 environment variable. The following
6071           table shows possible values.
6072
6073       trace2.perfTarget
6074           This variable controls the performance target destination. It may
6075           be overridden by the GIT_TRACE2_PERF environment variable. The
6076           following table shows possible values.
6077
6078       trace2.eventTarget
6079           This variable controls the event target destination. It may be
6080           overridden by the GIT_TRACE2_EVENT environment variable. The
6081           following table shows possible values.
6082
60830 or false - Disables the target.
6084
60851 or true - Writes to STDERR.
6086
6087[2-9] - Writes to the already opened file descriptor.
6088
6089<absolute-pathname> - Writes to the file in append mode. If the
6090               target already exists and is a directory, the traces will be
6091               written to files (one per process) underneath the given
6092               directory.
6093
6094af_unix:[<socket_type>:]<absolute-pathname> - Write to a Unix
6095               DomainSocket (on platforms that support them). Socket type can
6096               be either stream or dgram; if omitted Git will try both.
6097
6098       trace2.normalBrief
6099           Boolean. When true time, filename, and line fields are omitted from
6100           normal output. May be overridden by the GIT_TRACE2_BRIEF
6101           environment variable. Defaults to false.
6102
6103       trace2.perfBrief
6104           Boolean. When true time, filename, and line fields are omitted from
6105           PERF output. May be overridden by the GIT_TRACE2_PERF_BRIEF
6106           environment variable. Defaults to false.
6107
6108       trace2.eventBrief
6109           Boolean. When true time, filename, and line fields are omitted from
6110           event output. May be overridden by the GIT_TRACE2_EVENT_BRIEF
6111           environment variable. Defaults to false.
6112
6113       trace2.eventNesting
6114           Integer. Specifies desired depth of nested regions in the event
6115           output. Regions deeper than this value will be omitted. May be
6116           overridden by the GIT_TRACE2_EVENT_NESTING environment variable.
6117           Defaults to 2.
6118
6119       trace2.configParams
6120           A comma-separated list of patterns of "important" config settings
6121           that should be recorded in the trace2 output. For example,
6122           core.*,remote.*.url would cause the trace2 output to contain events
6123           listing each configured remote. May be overridden by the
6124           GIT_TRACE2_CONFIG_PARAMS environment variable. Unset by default.
6125
6126       trace2.envVars
6127           A comma-separated list of "important" environment variables that
6128           should be recorded in the trace2 output. For example,
6129           GIT_HTTP_USER_AGENT,GIT_CONFIG would cause the trace2 output to
6130           contain events listing the overrides for HTTP user agent and the
6131           location of the Git configuration file (assuming any are set). May
6132           be overridden by the GIT_TRACE2_ENV_VARS environment variable.
6133           Unset by default.
6134
6135       trace2.destinationDebug
6136           Boolean. When true Git will print error messages when a trace
6137           target destination cannot be opened for writing. By default, these
6138           errors are suppressed and tracing is silently disabled. May be
6139           overridden by the GIT_TRACE2_DST_DEBUG environment variable.
6140
6141       trace2.maxFiles
6142           Integer. When writing trace files to a target directory, do not
6143           write additional traces if doing so would exceed this many files.
6144           Instead, write a sentinel file that will block further tracing to
6145           this directory. Defaults to 0, which disables this check.
6146
6147       transfer.credentialsInUrl
6148           A configured URL can contain plaintext credentials in the form
6149           <protocol>://<user>:<password>@<domain>/<path>. You may want to
6150           warn or forbid the use of such configuration (in favor of using
6151           git-credential(1)). This will be used on git-clone(1), git-
6152           fetch(1), git-push(1), and any other direct use of the configured
6153           URL.
6154
6155           Note that this is currently limited to detecting credentials in
6156           remote.<name>.url configuration; it won’t detect credentials in
6157           remote.<name>.pushurl configuration.
6158
6159           You might want to enable this to prevent inadvertent credentials
6160           exposure, e.g. because:
6161
6162           •   The OS or system where you’re running git may not provide a way
6163               or otherwise allow you to configure the permissions of the
6164               configuration file where the username and/or password are
6165               stored.
6166
6167           •   Even if it does, having such data stored "at rest" might expose
6168               you in other ways, e.g. a backup process might copy the data to
6169               another system.
6170
6171           •   The git programs will pass the full URL to one another as
6172               arguments on the command-line, meaning the credentials will be
6173               exposed to other unprivileged users on systems that allow them
6174               to see the full process list of other users. On linux the
6175               "hidepid" setting documented in procfs(5) allows for
6176               configuring this behavior.
6177
6178               If such concerns don’t apply to you then you probably don’t
6179               need to be concerned about credentials exposure due to storing
6180               sensitive data in git’s configuration files. If you do want to
6181               use this, set transfer.credentialsInUrl to one of these values:
6182
6183allow (default): Git will proceed with its activity without
6184               warning.
6185
6186warn: Git will write a warning message to stderr when parsing a
6187               URL with a plaintext credential.
6188
6189die: Git will write a failure message to stderr when parsing a
6190               URL with a plaintext credential.
6191
6192       transfer.fsckObjects
6193           When fetch.fsckObjects or receive.fsckObjects are not set, the
6194           value of this variable is used instead. Defaults to false.
6195
6196           When set, the fetch or receive will abort in the case of a
6197           malformed object or a link to a nonexistent object. In addition,
6198           various other issues are checked for, including legacy issues (see
6199           fsck.<msg-id>), and potential security issues like the existence of
6200           a .GIT directory or a malicious .gitmodules file (see the release
6201           notes for v2.2.1 and v2.17.1 for details). Other sanity and
6202           security checks may be added in future releases.
6203
6204           On the receiving side, failing fsckObjects will make those objects
6205           unreachable, see "QUARANTINE ENVIRONMENT" in git-receive-pack(1).
6206           On the fetch side, malformed objects will instead be left
6207           unreferenced in the repository.
6208
6209           Due to the non-quarantine nature of the fetch.fsckObjects
6210           implementation it cannot be relied upon to leave the object store
6211           clean like receive.fsckObjects can.
6212
6213           As objects are unpacked they’re written to the object store, so
6214           there can be cases where malicious objects get introduced even
6215           though the "fetch" failed, only to have a subsequent "fetch"
6216           succeed because only new incoming objects are checked, not those
6217           that have already been written to the object store. That difference
6218           in behavior should not be relied upon. In the future, such objects
6219           may be quarantined for "fetch" as well.
6220
6221           For now, the paranoid need to find some way to emulate the
6222           quarantine environment if they’d like the same protection as
6223           "push". E.g. in the case of an internal mirror do the mirroring in
6224           two steps, one to fetch the untrusted objects, and then do a second
6225           "push" (which will use the quarantine) to another internal repo,
6226           and have internal clients consume this pushed-to repository, or
6227           embargo internal fetches and only allow them once a full "fsck" has
6228           run (and no new fetches have happened in the meantime).
6229
6230       transfer.hideRefs
6231           String(s) receive-pack and upload-pack use to decide which refs to
6232           omit from their initial advertisements. Use more than one
6233           definition to specify multiple prefix strings. A ref that is under
6234           the hierarchies listed in the value of this variable is excluded,
6235           and is hidden when responding to git push or git fetch. See
6236           receive.hideRefs and uploadpack.hideRefs for program-specific
6237           versions of this config.
6238
6239           You may also include a !  in front of the ref name to negate the
6240           entry, explicitly exposing it, even if an earlier entry marked it
6241           as hidden. If you have multiple hideRefs values, later entries
6242           override earlier ones (and entries in more-specific config files
6243           override less-specific ones).
6244
6245           If a namespace is in use, the namespace prefix is stripped from
6246           each reference before it is matched against transfer.hiderefs
6247           patterns. In order to match refs before stripping, add a ^ in front
6248           of the ref name. If you combine !  and ^, !  must be specified
6249           first.
6250
6251           For example, if refs/heads/master is specified in transfer.hideRefs
6252           and the current namespace is foo, then
6253           refs/namespaces/foo/refs/heads/master is omitted from the
6254           advertisements. If uploadpack.allowRefInWant is set, upload-pack
6255           will treat want-ref refs/heads/master in a protocol v2 fetch
6256           command as if refs/namespaces/foo/refs/heads/master did not exist.
6257           receive-pack, on the other hand, will still advertise the object id
6258           the ref is pointing to without mentioning its name (a so-called
6259           ".have" line).
6260
6261           Even if you hide refs, a client may still be able to steal the
6262           target objects via the techniques described in the "SECURITY"
6263           section of the gitnamespaces(7) man page; it’s best to keep private
6264           data in a separate repository.
6265
6266       transfer.unpackLimit
6267           When fetch.unpackLimit or receive.unpackLimit are not set, the
6268           value of this variable is used instead. The default value is 100.
6269
6270       transfer.advertiseSID
6271           Boolean. When true, client and server processes will advertise
6272           their unique session IDs to their remote counterpart. Defaults to
6273           false.
6274
6275       transfer.bundleURI
6276           When true, local git clone commands will request bundle information
6277           from the remote server (if advertised) and download bundles before
6278           continuing the clone through the Git protocol. Defaults to false.
6279
6280       uploadarchive.allowUnreachable
6281           If true, allow clients to use git archive --remote to request any
6282           tree, whether reachable from the ref tips or not. See the
6283           discussion in the "SECURITY" section of git-upload-archive(1) for
6284           more details. Defaults to false.
6285
6286       uploadpack.hideRefs
6287           This variable is the same as transfer.hideRefs, but applies only to
6288           upload-pack (and so affects only fetches, not pushes). An attempt
6289           to fetch a hidden ref by git fetch will fail. See also
6290           uploadpack.allowTipSHA1InWant.
6291
6292       uploadpack.allowTipSHA1InWant
6293           When uploadpack.hideRefs is in effect, allow upload-pack to accept
6294           a fetch request that asks for an object at the tip of a hidden ref
6295           (by default, such a request is rejected). See also
6296           uploadpack.hideRefs. Even if this is false, a client may be able to
6297           steal objects via the techniques described in the "SECURITY"
6298           section of the gitnamespaces(7) man page; it’s best to keep private
6299           data in a separate repository.
6300
6301       uploadpack.allowReachableSHA1InWant
6302           Allow upload-pack to accept a fetch request that asks for an object
6303           that is reachable from any ref tip. However, note that calculating
6304           object reachability is computationally expensive. Defaults to
6305           false. Even if this is false, a client may be able to steal objects
6306           via the techniques described in the "SECURITY" section of the
6307           gitnamespaces(7) man page; it’s best to keep private data in a
6308           separate repository.
6309
6310       uploadpack.allowAnySHA1InWant
6311           Allow upload-pack to accept a fetch request that asks for any
6312           object at all. Defaults to false.
6313
6314       uploadpack.keepAlive
6315           When upload-pack has started pack-objects, there may be a quiet
6316           period while pack-objects prepares the pack. Normally it would
6317           output progress information, but if --quiet was used for the fetch,
6318           pack-objects will output nothing at all until the pack data begins.
6319           Some clients and networks may consider the server to be hung and
6320           give up. Setting this option instructs upload-pack to send an empty
6321           keepalive packet every uploadpack.keepAlive seconds. Setting this
6322           option to 0 disables keepalive packets entirely. The default is 5
6323           seconds.
6324
6325       uploadpack.packObjectsHook
6326           If this option is set, when upload-pack would run git pack-objects
6327           to create a packfile for a client, it will run this shell command
6328           instead. The pack-objects command and arguments it would have run
6329           (including the git pack-objects at the beginning) are appended to
6330           the shell command. The stdin and stdout of the hook are treated as
6331           if pack-objects itself was run. I.e., upload-pack will feed input
6332           intended for pack-objects to the hook, and expects a completed
6333           packfile on stdout.
6334
6335           Note that this configuration variable is only respected when it is
6336           specified in protected configuration (see the section called
6337           “SCOPES”). This is a safety measure against fetching from untrusted
6338           repositories.
6339
6340       uploadpack.allowFilter
6341           If this option is set, upload-pack will support partial clone and
6342           partial fetch object filtering.
6343
6344       uploadpackfilter.allow
6345           Provides a default value for unspecified object filters (see: the
6346           below configuration variable). If set to true, this will also
6347           enable all filters which get added in the future. Defaults to true.
6348
6349       uploadpackfilter.<filter>.allow
6350           Explicitly allow or ban the object filter corresponding to
6351           <filter>, where <filter> may be one of: blob:none, blob:limit,
6352           object:type, tree, sparse:oid, or combine. If using combined
6353           filters, both combine and all of the nested filter kinds must be
6354           allowed. Defaults to uploadpackfilter.allow.
6355
6356       uploadpackfilter.tree.maxDepth
6357           Only allow --filter=tree:<n> when <n> is no more than the value of
6358           uploadpackfilter.tree.maxDepth. If set, this also implies
6359           uploadpackfilter.tree.allow=true, unless this configuration
6360           variable had already been set. Has no effect if unset.
6361
6362       uploadpack.allowRefInWant
6363           If this option is set, upload-pack will support the ref-in-want
6364           feature of the protocol version 2 fetch command. This feature is
6365           intended for the benefit of load-balanced servers which may not
6366           have the same view of what OIDs their refs point to due to
6367           replication delay.
6368
6369       url.<base>.insteadOf
6370           Any URL that starts with this value will be rewritten to start,
6371           instead, with <base>. In cases where some site serves a large
6372           number of repositories, and serves them with multiple access
6373           methods, and some users need to use different access methods, this
6374           feature allows people to specify any of the equivalent URLs and
6375           have Git automatically rewrite the URL to the best alternative for
6376           the particular user, even for a never-before-seen repository on the
6377           site. When more than one insteadOf strings match a given URL, the
6378           longest match is used.
6379
6380           Note that any protocol restrictions will be applied to the
6381           rewritten URL. If the rewrite changes the URL to use a custom
6382           protocol or remote helper, you may need to adjust the
6383           protocol.*.allow config to permit the request. In particular,
6384           protocols you expect to use for submodules must be set to always
6385           rather than the default of user. See the description of
6386           protocol.allow above.
6387
6388       url.<base>.pushInsteadOf
6389           Any URL that starts with this value will not be pushed to; instead,
6390           it will be rewritten to start with <base>, and the resulting URL
6391           will be pushed to. In cases where some site serves a large number
6392           of repositories, and serves them with multiple access methods, some
6393           of which do not allow push, this feature allows people to specify a
6394           pull-only URL and have Git automatically use an appropriate URL to
6395           push, even for a never-before-seen repository on the site. When
6396           more than one pushInsteadOf strings match a given URL, the longest
6397           match is used. If a remote has an explicit pushurl, Git will ignore
6398           this setting for that remote.
6399
6400       user.name, user.email, author.name, author.email, committer.name,
6401       committer.email
6402           The user.name and user.email variables determine what ends up in
6403           the author and committer fields of commit objects. If you need the
6404           author or committer to be different, the author.name, author.email,
6405           committer.name, or committer.email variables can be set. All of
6406           these can be overridden by the GIT_AUTHOR_NAME, GIT_AUTHOR_EMAIL,
6407           GIT_COMMITTER_NAME, GIT_COMMITTER_EMAIL, and EMAIL environment
6408           variables.
6409
6410           Note that the name forms of these variables conventionally refer to
6411           some form of a personal name. See git-commit(1) and the environment
6412           variables section of git(1) for more information on these settings
6413           and the credential.username option if you’re looking for
6414           authentication credentials instead.
6415
6416       user.useConfigOnly
6417           Instruct Git to avoid trying to guess defaults for user.email and
6418           user.name, and instead retrieve the values only from the
6419           configuration. For example, if you have multiple email addresses
6420           and would like to use a different one for each repository, then
6421           with this configuration option set to true in the global config
6422           along with a name, Git will prompt you to set up an email before
6423           making new commits in a newly cloned repository. Defaults to false.
6424
6425       user.signingKey
6426           If git-tag(1) or git-commit(1) is not selecting the key you want it
6427           to automatically when creating a signed tag or commit, you can
6428           override the default selection with this variable. This option is
6429           passed unchanged to gpg’s --local-user parameter, so you may
6430           specify a key using any method that gpg supports. If gpg.format is
6431           set to ssh this can contain the path to either your private ssh key
6432           or the public key when ssh-agent is used. Alternatively it can
6433           contain a public key prefixed with key:: directly (e.g.:
6434           "key::ssh-rsa XXXXXX identifier"). The private key needs to be
6435           available via ssh-agent. If not set Git will call
6436           gpg.ssh.defaultKeyCommand (e.g.: "ssh-add -L") and try to use the
6437           first key available. For backward compatibility, a raw key which
6438           begins with "ssh-", such as "ssh-rsa XXXXXX identifier", is treated
6439           as "key::ssh-rsa XXXXXX identifier", but this form is deprecated;
6440           use the key:: form instead.
6441
6442       versionsort.prereleaseSuffix (deprecated)
6443           Deprecated alias for versionsort.suffix. Ignored if
6444           versionsort.suffix is set.
6445
6446       versionsort.suffix
6447           Even when version sort is used in git-tag(1), tagnames with the
6448           same base version but different suffixes are still sorted
6449           lexicographically, resulting e.g. in prerelease tags appearing
6450           after the main release (e.g. "1.0-rc1" after "1.0"). This variable
6451           can be specified to determine the sorting order of tags with
6452           different suffixes.
6453
6454           By specifying a single suffix in this variable, any tagname
6455           containing that suffix will appear before the corresponding main
6456           release. E.g. if the variable is set to "-rc", then all "1.0-rcX"
6457           tags will appear before "1.0". If specified multiple times, once
6458           per suffix, then the order of suffixes in the configuration will
6459           determine the sorting order of tagnames with those suffixes. E.g.
6460           if "-pre" appears before "-rc" in the configuration, then all
6461           "1.0-preX" tags will be listed before any "1.0-rcX" tags. The
6462           placement of the main release tag relative to tags with various
6463           suffixes can be determined by specifying the empty suffix among
6464           those other suffixes. E.g. if the suffixes "-rc", "", "-ck", and
6465           "-bfs" appear in the configuration in this order, then all
6466           "v4.8-rcX" tags are listed first, followed by "v4.8", then
6467           "v4.8-ckX" and finally "v4.8-bfsX".
6468
6469           If more than one suffix matches the same tagname, then that tagname
6470           will be sorted according to the suffix which starts at the earliest
6471           position in the tagname. If more than one different matching suffix
6472           starts at that earliest position, then that tagname will be sorted
6473           according to the longest of those suffixes. The sorting order
6474           between different suffixes is undefined if they are in multiple
6475           config files.
6476
6477       web.browser
6478           Specify a web browser that may be used by some commands. Currently
6479           only git-instaweb(1) and git-help(1) may use it.
6480
6481       worktree.guessRemote
6482           If no branch is specified and neither -b nor -B nor --detach is
6483           used, then git worktree add defaults to creating a new branch from
6484           HEAD. If worktree.guessRemote is set to true, worktree add tries to
6485           find a remote-tracking branch whose name uniquely matches the new
6486           branch name. If such a branch exists, it is checked out and set as
6487           "upstream" for the new branch. If no such match can be found, it
6488           falls back to creating a new branch from the current HEAD.
6489

BUGS

6491       When using the deprecated [section.subsection] syntax, changing a value
6492       will result in adding a multi-line key instead of a change, if the
6493       subsection is given with at least one uppercase character. For example
6494       when the config looks like
6495
6496             [section.subsection]
6497               key = value1
6498
6499       and running git config section.Subsection.key value2 will result in
6500
6501             [section.subsection]
6502               key = value1
6503               key = value2
