6 git-log - Show commit logs
7
9 git log [<options>] [<revision-range>] [[--] <path>...]
10
12 Shows the commit logs.
13
14 List commits that are reachable by following the parent links from the
15 given commit(s), but exclude commits that are reachable from the one(s)
16 given with a ^ in front of them. The output is given in reverse
17 chronological order by default.
18
19 You can think of this as a set operation. Commits reachable from any of
20 the commits given on the command line form a set, and then commits
21 reachable from any of the ones given with ^ in front are subtracted
22 from that set. The remaining commits are what comes out in the
23 command’s output. Various other options and paths parameters can be
24 used to further limit the result.
25
26 Thus, the following command:
27
28 $ git log foo bar ^baz
29
30 means "list all the commits which are reachable from foo or bar, but
31 not from baz".
32
33 A special notation "<commit1>..<commit2>" can be used as a short-hand
34 for "^<commit1> <commit2>". For example, either of the following may be
35 used interchangeably:
36
37 $ git log origin..HEAD
38 $ git log HEAD ^origin
39
40 Another special notation is "<commit1>...<commit2>" which is useful for
41 merges. The resulting set of commits is the symmetric difference
42 between the two operands. The following two commands are equivalent:
43
44 $ git log A B --not $(git merge-base --all A B)
45 $ git log A...B
46
47 The command takes options applicable to the git-rev-list(1) command to
48 control what is shown and how, and options applicable to the git-
49 diff(1) command to control how the changes each commit introduces are
50 shown.
51
53 --follow
54 Continue listing the history of a file beyond renames (works only
55 for a single file).
56
57 --no-decorate, --decorate[=short|full|auto|no]
58 Print out the ref names of any commits that are shown. If short is
59 specified, the ref name prefixes refs/heads/, refs/tags/ and
60 refs/remotes/ will not be printed. If full is specified, the full
61 ref name (including prefix) will be printed. If auto is specified,
62 then if the output is going to a terminal, the ref names are shown
63 as if short were given, otherwise no ref names are shown. The
64 option --decorate is short-hand for --decorate=short. Default to
65 configuration value of log.decorate if configured, otherwise, auto.
66
67 --decorate-refs=<pattern>, --decorate-refs-exclude=<pattern>
68 For each candidate reference, do not use it for decoration if it
69 matches any patterns given to --decorate-refs-exclude or if it
70 doesn’t match any of the patterns given to --decorate-refs. The
71 log.excludeDecoration config option allows excluding refs from the
72 decorations, but an explicit --decorate-refs pattern will override
73 a match in log.excludeDecoration.
74
75 If none of these options or config settings are given, then
76 references are used as decoration if they match HEAD, refs/heads/,
77 refs/remotes/, refs/stash/, or refs/tags/.
78
79 --clear-decorations
80 When specified, this option clears all previous --decorate-refs or
81 --decorate-refs-exclude options and relaxes the default decoration
82 filter to include all references. This option is assumed if the
83 config value log.initialDecorationSet is set to all.
84
85 --source
86 Print out the ref name given on the command line by which each
87 commit was reached.
88
89 --[no-]mailmap, --[no-]use-mailmap
90 Use mailmap file to map author and committer names and email
91 addresses to canonical real names and email addresses. See git-
92 shortlog(1).
93
94 --full-diff
95 Without this flag, git log -p <path>... shows commits that touch
96 the specified paths, and diffs about the same specified paths. With
97 this, the full diff is shown for commits that touch the specified
98 paths; this means that "<path>..." limits only commits, and doesn’t
99 limit diff for those commits.
100
101 Note that this affects all diff-based output types, e.g. those
102 produced by --stat, etc.
103
104 --log-size
105 Include a line “log size <number>” in the output for each commit,
106 where <number> is the length of that commit’s message in bytes.
107 Intended to speed up tools that read log messages from git log
108 output by allowing them to allocate space in advance.
109
110 -L<start>,<end>:<file>, -L:<funcname>:<file>
111 Trace the evolution of the line range given by <start>,<end>, or by
112 the function name regex <funcname>, within the <file>. You may not
113 give any pathspec limiters. This is currently limited to a walk
114 starting from a single revision, i.e., you may only give zero or
115 one positive revision arguments, and <start> and <end> (or
116 <funcname>) must exist in the starting revision. You can specify
117 this option more than once. Implies --patch. Patch output can be
118 suppressed using --no-patch, but other diff formats (namely --raw,
119 --numstat, --shortstat, --dirstat, --summary, --name-only,
120 --name-status, --check) are not currently implemented.
121
122 <start> and <end> can take one of these forms:
123
124 • number
125
126 If <start> or <end> is a number, it specifies an absolute line
127 number (lines count from 1).
128
129 • /regex/
130
131 This form will use the first line matching the given POSIX
132 regex. If <start> is a regex, it will search from the end of
133 the previous -L range, if any, otherwise from the start of
134 file. If <start> is ^/regex/, it will search from the start of
135 file. If <end> is a regex, it will search starting at the line
136 given by <start>.
137
138 • +offset or -offset
139
140 This is only valid for <end> and will specify a number of lines
141 before or after the line given by <start>.
142
143 If :<funcname> is given in place of <start> and <end>, it is a
144 regular expression that denotes the range from the first funcname
145 line that matches <funcname>, up to the next funcname line.
146 :<funcname> searches from the end of the previous -L range, if any,
147 otherwise from the start of file. ^:<funcname> searches from the
148 start of file. The function names are determined in the same way as
149 git diff works out patch hunk headers (see Defining a custom
150 hunk-header in gitattributes(5)).
151
152 <revision-range>
153 Show only commits in the specified revision range. When no
154 <revision-range> is specified, it defaults to HEAD (i.e. the whole
155 history leading to the current commit). origin..HEAD specifies all
156 the commits reachable from the current commit (i.e. HEAD), but not
157 from origin. For a complete list of ways to spell <revision-range>,
158 see the Specifying Ranges section of gitrevisions(7).
159
160 [--] <path>...
161 Show only commits that are enough to explain how the files that
162 match the specified paths came to be. See History Simplification
163 below for details and other simplification modes.
164
165 Paths may need to be prefixed with -- to separate them from options
166 or the revision range, when confusion arises.
167
168 Commit Limiting
169 Besides specifying a range of commits that should be listed using the
170 special notations explained in the description, additional commit
171 limiting may be applied.
172
173 Using more options generally further limits the output (e.g.
174 --since=<date1> limits to commits newer than <date1>, and using it with
175 --grep=<pattern> further limits to commits whose log message has a line
176 that matches <pattern>), unless otherwise noted.
177
178 Note that these are applied before commit ordering and formatting
179 options, such as --reverse.
180
181 -<number>, -n <number>, --max-count=<number>
182 Limit the number of commits to output.
183
184 --skip=<number>
185 Skip number commits before starting to show the commit output.
186
187 --since=<date>, --after=<date>
188 Show commits more recent than a specific date.
189
190 --since-as-filter=<date>
191 Show all commits more recent than a specific date. This visits all
192 commits in the range, rather than stopping at the first commit
193 which is older than a specific date.
194
195 --until=<date>, --before=<date>
196 Show commits older than a specific date.
197
198 --author=<pattern>, --committer=<pattern>
199 Limit the commits output to ones with author/committer header lines
200 that match the specified pattern (regular expression). With more
201 than one --author=<pattern>, commits whose author matches any of
202 the given patterns are chosen (similarly for multiple
203 --committer=<pattern>).
204
205 --grep-reflog=<pattern>
206 Limit the commits output to ones with reflog entries that match the
207 specified pattern (regular expression). With more than one
208 --grep-reflog, commits whose reflog message matches any of the
209 given patterns are chosen. It is an error to use this option unless
210 --walk-reflogs is in use.
211
212 --grep=<pattern>
213 Limit the commits output to ones with log message that matches the
214 specified pattern (regular expression). With more than one
215 --grep=<pattern>, commits whose message matches any of the given
216 patterns are chosen (but see --all-match).
217
218 When --notes is in effect, the message from the notes is matched as
219 if it were part of the log message.
220
221 --all-match
222 Limit the commits output to ones that match all given --grep,
223 instead of ones that match at least one.
224
225 --invert-grep
226 Limit the commits output to ones with log message that do not match
227 the pattern specified with --grep=<pattern>.
228
229 -i, --regexp-ignore-case
230 Match the regular expression limiting patterns without regard to
231 letter case.
232
233 --basic-regexp
234 Consider the limiting patterns to be basic regular expressions;
235 this is the default.
236
237 -E, --extended-regexp
238 Consider the limiting patterns to be extended regular expressions
239 instead of the default basic regular expressions.
240
241 -F, --fixed-strings
242 Consider the limiting patterns to be fixed strings (don’t interpret
243 pattern as a regular expression).
244
245 -P, --perl-regexp
246 Consider the limiting patterns to be Perl-compatible regular
247 expressions.
248
249 Support for these types of regular expressions is an optional
250 compile-time dependency. If Git wasn’t compiled with support for
251 them providing this option will cause it to die.
252
253 --remove-empty
254 Stop when a given path disappears from the tree.
255
256 --merges
257 Print only merge commits. This is exactly the same as
258 --min-parents=2.
259
260 --no-merges
261 Do not print commits with more than one parent. This is exactly the
262 same as --max-parents=1.
263
264 --min-parents=<number>, --max-parents=<number>, --no-min-parents,
265 --no-max-parents
266 Show only commits which have at least (or at most) that many parent
267 commits. In particular, --max-parents=1 is the same as --no-merges,
268 --min-parents=2 is the same as --merges. --max-parents=0 gives all
269 root commits and --min-parents=3 all octopus merges.
270
271 --no-min-parents and --no-max-parents reset these limits (to no
272 limit) again. Equivalent forms are --min-parents=0 (any commit has
273 0 or more parents) and --max-parents=-1 (negative numbers denote no
274 upper limit).
275
276 --first-parent
277 When finding commits to include, follow only the first parent
278 commit upon seeing a merge commit. This option can give a better
279 overview when viewing the evolution of a particular topic branch,
280 because merges into a topic branch tend to be only about adjusting
281 to updated upstream from time to time, and this option allows you
282 to ignore the individual commits brought in to your history by such
283 a merge.
284
285 This option also changes default diff format for merge commits to
286 first-parent, see --diff-merges=first-parent for details.
287
288 --exclude-first-parent-only
289 When finding commits to exclude (with a ^), follow only the first
290 parent commit upon seeing a merge commit. This can be used to find
291 the set of changes in a topic branch from the point where it
292 diverged from the remote branch, given that arbitrary merges can be
293 valid topic branch changes.
294
295 --not
296 Reverses the meaning of the ^ prefix (or lack thereof) for all
297 following revision specifiers, up to the next --not.
298
299 --all
300 Pretend as if all the refs in refs/, along with HEAD, are listed on
301 the command line as <commit>.
302
303 --branches[=<pattern>]
304 Pretend as if all the refs in refs/heads are listed on the command
305 line as <commit>. If <pattern> is given, limit branches to ones
306 matching given shell glob. If pattern lacks ?, *, or [, /* at the
307 end is implied.
308
309 --tags[=<pattern>]
310 Pretend as if all the refs in refs/tags are listed on the command
311 line as <commit>. If <pattern> is given, limit tags to ones
312 matching given shell glob. If pattern lacks ?, *, or [, /* at the
313 end is implied.
314
315 --remotes[=<pattern>]
316 Pretend as if all the refs in refs/remotes are listed on the
317 command line as <commit>. If <pattern> is given, limit
318 remote-tracking branches to ones matching given shell glob. If
319 pattern lacks ?, *, or [, /* at the end is implied.
320
321 --glob=<glob-pattern>
322 Pretend as if all the refs matching shell glob <glob-pattern> are
323 listed on the command line as <commit>. Leading refs/, is
324 automatically prepended if missing. If pattern lacks ?, *, or [, /*
325 at the end is implied.
326
327 --exclude=<glob-pattern>
328 Do not include refs matching <glob-pattern> that the next --all,
329 --branches, --tags, --remotes, or --glob would otherwise consider.
330 Repetitions of this option accumulate exclusion patterns up to the
331 next --all, --branches, --tags, --remotes, or --glob option (other
332 options or arguments do not clear accumulated patterns).
333
334 The patterns given should not begin with refs/heads, refs/tags, or
335 refs/remotes when applied to --branches, --tags, or --remotes,
336 respectively, and they must begin with refs/ when applied to --glob
337 or --all. If a trailing /* is intended, it must be given
338 explicitly.
339
340 --exclude-hidden=[receive|uploadpack]
341 Do not include refs that would be hidden by git-receive-pack or
342 git-upload-pack by consulting the appropriate receive.hideRefs or
343 uploadpack.hideRefs configuration along with transfer.hideRefs (see
344 git-config(1)). This option affects the next pseudo-ref option
345 --all or --glob and is cleared after processing them.
346
347 --reflog
348 Pretend as if all objects mentioned by reflogs are listed on the
349 command line as <commit>.
350
351 --alternate-refs
352 Pretend as if all objects mentioned as ref tips of alternate
353 repositories were listed on the command line. An alternate
354 repository is any repository whose object directory is specified in
355 objects/info/alternates. The set of included objects may be
356 modified by core.alternateRefsCommand, etc. See git-config(1).
357
358 --single-worktree
359 By default, all working trees will be examined by the following
360 options when there are more than one (see git-worktree(1)): --all,
361 --reflog and --indexed-objects. This option forces them to examine
362 the current working tree only.
363
364 --ignore-missing
365 Upon seeing an invalid object name in the input, pretend as if the
366 bad input was not given.
367
368 --bisect
369 Pretend as if the bad bisection ref refs/bisect/bad was listed and
370 as if it was followed by --not and the good bisection refs
371 refs/bisect/good-* on the command line.
372
373 --stdin
374 In addition to the <commit> listed on the command line, read them
375 from the standard input. If a -- separator is seen, stop reading
376 commits and start reading paths to limit the result.
377
378 --cherry-mark
379 Like --cherry-pick (see below) but mark equivalent commits with =
380 rather than omitting them, and inequivalent ones with +.
381
382 --cherry-pick
383 Omit any commit that introduces the same change as another commit
384 on the “other side” when the set of commits are limited with
385 symmetric difference.
386
387 For example, if you have two branches, A and B, a usual way to list
388 all commits on only one side of them is with --left-right (see the
389 example below in the description of the --left-right option).
390 However, it shows the commits that were cherry-picked from the
391 other branch (for example, “3rd on b” may be cherry-picked from
392 branch A). With this option, such pairs of commits are excluded
393 from the output.
394
395 --left-only, --right-only
396 List only commits on the respective side of a symmetric difference,
397 i.e. only those which would be marked < resp. > by --left-right.
398
399 For example, --cherry-pick --right-only A...B omits those commits
400 from B which are in A or are patch-equivalent to a commit in A. In
401 other words, this lists the + commits from git cherry A B. More
402 precisely, --cherry-pick --right-only --no-merges gives the exact
403 list.
404
405 --cherry
406 A synonym for --right-only --cherry-mark --no-merges; useful to
407 limit the output to the commits on our side and mark those that
408 have been applied to the other side of a forked history with git
409 log --cherry upstream...mybranch, similar to git cherry upstream
410 mybranch.
411
412 -g, --walk-reflogs
413 Instead of walking the commit ancestry chain, walk reflog entries
414 from the most recent one to older ones. When this option is used
415 you cannot specify commits to exclude (that is, ^commit,
416 commit1..commit2, and commit1...commit2 notations cannot be used).
417
418 With --pretty format other than oneline and reference (for obvious
419 reasons), this causes the output to have two extra lines of
420 information taken from the reflog. The reflog designator in the
421 output may be shown as ref@{Nth} (where Nth is the
422 reverse-chronological index in the reflog) or as ref@{timestamp}
423 (with the timestamp for that entry), depending on a few rules:
424
425 1. If the starting point is specified as ref@{Nth}, show the index
426 format.
427
428 2. If the starting point was specified as ref@{now}, show the
429 timestamp format.
430
431 3. If neither was used, but --date was given on the command line,
432 show the timestamp in the format requested by --date.
433
434 4. Otherwise, show the index format.
435
436 Under --pretty=oneline, the commit message is prefixed with this
437 information on the same line. This option cannot be combined with
438 --reverse. See also git-reflog(1).
439
440 Under --pretty=reference, this information will not be shown at
441 all.
442
443 --merge
444 After a failed merge, show refs that touch files having a conflict
445 and don’t exist on all heads to merge.
446
447 --boundary
448 Output excluded boundary commits. Boundary commits are prefixed
449 with -.
450
451 History Simplification
452 Sometimes you are only interested in parts of the history, for example
453 the commits modifying a particular <path>. But there are two parts of
454 History Simplification, one part is selecting the commits and the other
455 is how to do it, as there are various strategies to simplify the
456 history.
457
458 The following options select the commits to be shown:
459
460 <paths>
461 Commits modifying the given <paths> are selected.
462
463 --simplify-by-decoration
464 Commits that are referred by some branch or tag are selected.
465
466 Note that extra commits can be shown to give a meaningful history.
467
468 The following options affect the way the simplification is performed:
469
470 Default mode
471 Simplifies the history to the simplest history explaining the final
472 state of the tree. Simplest because it prunes some side branches if
473 the end result is the same (i.e. merging branches with the same
474 content)
475
476 --show-pulls
477 Include all commits from the default mode, but also any merge
478 commits that are not TREESAME to the first parent but are TREESAME
479 to a later parent. This mode is helpful for showing the merge
480 commits that "first introduced" a change to a branch.
481
482 --full-history
483 Same as the default mode, but does not prune some history.
484
485 --dense
486 Only the selected commits are shown, plus some to have a meaningful
487 history.
488
489 --sparse
490 All commits in the simplified history are shown.
491
492 --simplify-merges
493 Additional option to --full-history to remove some needless merges
494 from the resulting history, as there are no selected commits
495 contributing to this merge.
496
497 --ancestry-path[=<commit>]
498 When given a range of commits to display (e.g. commit1..commit2 or
499 commit2 ^commit1), only display commits in that range that are
500 ancestors of <commit>, descendants of <commit>, or <commit> itself.
501 If no commit is specified, use commit1 (the excluded part of the
502 range) as <commit>. Can be passed multiple times; if so, a commit
503 is included if it is any of the commits given or if it is an
504 ancestor or descendant of one of them.
505
506 A more detailed explanation follows.
507
508 Suppose you specified foo as the <paths>. We shall call commits that
509 modify foo !TREESAME, and the rest TREESAME. (In a diff filtered for
510 foo, they look different and equal, respectively.)
511
512 In the following, we will always refer to the same example history to
513 illustrate the differences between simplification settings. We assume
514 that you are filtering for a file foo in this commit graph:
515
516 .-A---M---N---O---P---Q
517 / / / / / /
518 I B C D E Y
519 \ / / / / /
520 `-------------' X
521
522 The horizontal line of history A---Q is taken to be the first parent of
523 each merge. The commits are:
524
525 • I is the initial commit, in which foo exists with contents “asdf”,
526 and a file quux exists with contents “quux”. Initial commits are
527 compared to an empty tree, so I is !TREESAME.
528
529 • In A, foo contains just “foo”.
530
531 • B contains the same change as A. Its merge M is trivial and hence
532 TREESAME to all parents.
533
534 • C does not change foo, but its merge N changes it to “foobar”, so
535 it is not TREESAME to any parent.
536
537 • D sets foo to “baz”. Its merge O combines the strings from N and D
538 to “foobarbaz”; i.e., it is not TREESAME to any parent.
539
540 • E changes quux to “xyzzy”, and its merge P combines the strings to
541 “quux xyzzy”. P is TREESAME to O, but not to E.
542
543 • X is an independent root commit that added a new file side, and Y
544 modified it. Y is TREESAME to X. Its merge Q added side to P, and
545 Q is TREESAME to P, but not to Y.
546
547 rev-list walks backwards through history, including or excluding
548 commits based on whether --full-history and/or parent rewriting (via
549 --parents or --children) are used. The following settings are
550 available.
551
552 Default mode
553 Commits are included if they are not TREESAME to any parent (though
554 this can be changed, see --sparse below). If the commit was a
555 merge, and it was TREESAME to one parent, follow only that parent.
556 (Even if there are several TREESAME parents, follow only one of
557 them.) Otherwise, follow all parents.
558
559 This results in:
560
561 .-A---N---O
562 / / /
563 I---------D
564
565 Note how the rule to only follow the TREESAME parent, if one is
566 available, removed B from consideration entirely. C was considered
567 via N, but is TREESAME. Root commits are compared to an empty tree,
568 so I is !TREESAME.
569
570 Parent/child relations are only visible with --parents, but that
571 does not affect the commits selected in default mode, so we have
572 shown the parent lines.
573
574 --full-history without parent rewriting
575 This mode differs from the default in one point: always follow all
576 parents of a merge, even if it is TREESAME to one of them. Even if
577 more than one side of the merge has commits that are included, this
578 does not imply that the merge itself is! In the example, we get
579
580 I A B N D O P Q
581
582 M was excluded because it is TREESAME to both parents. E, C and B
583 were all walked, but only B was !TREESAME, so the others do not
584 appear.
585
586 Note that without parent rewriting, it is not really possible to
587 talk about the parent/child relationships between the commits, so
588 we show them disconnected.
589
590 --full-history with parent rewriting
591 Ordinary commits are only included if they are !TREESAME (though
592 this can be changed, see --sparse below).
593
594 Merges are always included. However, their parent list is
595 rewritten: Along each parent, prune away commits that are not
596 included themselves. This results in
597
598 .-A---M---N---O---P---Q
599 / / / / /
600 I B / D /
601 \ / / / /
602 `-------------'
603
604 Compare to --full-history without rewriting above. Note that E was
605 pruned away because it is TREESAME, but the parent list of P was
606 rewritten to contain E's parent I. The same happened for C and N,
607 and X, Y and Q.
608
609 In addition to the above settings, you can change whether TREESAME
610 affects inclusion:
611
612 --dense
613 Commits that are walked are included if they are not TREESAME to
614 any parent.
615
616 --sparse
617 All commits that are walked are included.
618
619 Note that without --full-history, this still simplifies merges: if
620 one of the parents is TREESAME, we follow only that one, so the
621 other sides of the merge are never walked.
622
623 --simplify-merges
624 First, build a history graph in the same way that --full-history
625 with parent rewriting does (see above).
626
627 Then simplify each commit C to its replacement C' in the final
628 history according to the following rules:
629
630 • Set C' to C.
631
632 • Replace each parent P of C' with its simplification P'. In the
633 process, drop parents that are ancestors of other parents or
634 that are root commits TREESAME to an empty tree, and remove
635 duplicates, but take care to never drop all parents that we are
636 TREESAME to.
637
638 • If after this parent rewriting, C' is a root or merge commit
639 (has zero or >1 parents), a boundary commit, or !TREESAME, it
640 remains. Otherwise, it is replaced with its only parent.
641
642 The effect of this is best shown by way of comparing to
643 --full-history with parent rewriting. The example turns into:
644
645 .-A---M---N---O
646 / / /
647 I B D
648 \ / /
649 `---------'
650
651 Note the major differences in N, P, and Q over --full-history:
652
653 • N's parent list had I removed, because it is an ancestor of the
654 other parent M. Still, N remained because it is !TREESAME.
655
656 • P's parent list similarly had I removed. P was then removed
657 completely, because it had one parent and is TREESAME.
658
659 • Q's parent list had Y simplified to X. X was then removed,
660 because it was a TREESAME root. Q was then removed completely,
661 because it had one parent and is TREESAME.
662
663 There is another simplification mode available:
664
665 --ancestry-path[=<commit>]
666 Limit the displayed commits to those which are an ancestor of
667 <commit>, or which are a descendant of <commit>, or are <commit>
668 itself.
669
670 As an example use case, consider the following commit history:
671
672 D---E-------F
673 / \ \
674 B---C---G---H---I---J
675 / \
676 A-------K---------------L--M
677
678 A regular D..M computes the set of commits that are ancestors of M,
679 but excludes the ones that are ancestors of D. This is useful to
680 see what happened to the history leading to M since D, in the sense
681 that “what does M have that did not exist in D”. The result in this
682 example would be all the commits, except A and B (and D itself, of
683 course).
684
685 When we want to find out what commits in M are contaminated with
686 the bug introduced by D and need fixing, however, we might want to
687 view only the subset of D..M that are actually descendants of D,
688 i.e. excluding C and K. This is exactly what the --ancestry-path
689 option does. Applied to the D..M range, it results in:
690
691 E-------F
692 \ \
693 G---H---I---J
694 \
695 L--M
696
697 We can also use --ancestry-path=D instead of --ancestry-path which
698 means the same thing when applied to the D..M range but is just
699 more explicit.
700
701 If we instead are interested in a given topic within this range,
702 and all commits affected by that topic, we may only want to view
703 the subset of D..M which contain that topic in their ancestry path.
704 So, using --ancestry-path=H D..M for example would result in:
705
706 E
707 \
708 G---H---I---J
709 \
710 L--M
711
712 Whereas --ancestry-path=K D..M would result in
713
714 K---------------L--M
715
716 Before discussing another option, --show-pulls, we need to create a new
717 example history.
718
719 A common problem users face when looking at simplified history is that
720 a commit they know changed a file somehow does not appear in the file’s
721 simplified history. Let’s demonstrate a new example and show how
722 options such as --full-history and --simplify-merges works in that
723 case:
724
725 .-A---M-----C--N---O---P
726 / / \ \ \/ / /
727 I B \ R-'`-Z' /
728 \ / \/ /
729 \ / /\ /
730 `---X--' `---Y--'
731
732 For this example, suppose I created file.txt which was modified by A,
733 B, and X in different ways. The single-parent commits C, Z, and Y do
734 not change file.txt. The merge commit M was created by resolving the
735 merge conflict to include both changes from A and B and hence is not
736 TREESAME to either. The merge commit R, however, was created by
737 ignoring the contents of file.txt at M and taking only the contents of
738 file.txt at X. Hence, R is TREESAME to X but not M. Finally, the
739 natural merge resolution to create N is to take the contents of
740 file.txt at R, so N is TREESAME to R but not C. The merge commits O and
741 P are TREESAME to their first parents, but not to their second parents,
742 Z and Y respectively.
743
744 When using the default mode, N and R both have a TREESAME parent, so
745 those edges are walked and the others are ignored. The resulting
746 history graph is:
747
748 I---X
749
750 When using --full-history, Git walks every edge. This will discover the
751 commits A and B and the merge M, but also will reveal the merge commits
752 O and P. With parent rewriting, the resulting graph is:
753
754 .-A---M--------N---O---P
755 / / \ \ \/ / /
756 I B \ R-'`--' /
757 \ / \/ /
758 \ / /\ /
759 `---X--' `------'
760
761 Here, the merge commits O and P contribute extra noise, as they did not
762 actually contribute a change to file.txt. They only merged a topic that
763 was based on an older version of file.txt. This is a common issue in
764 repositories using a workflow where many contributors work in parallel
765 and merge their topic branches along a single trunk: many unrelated
766 merges appear in the --full-history results.
767
768 When using the --simplify-merges option, the commits O and P disappear
769 from the results. This is because the rewritten second parents of O and
770 P are reachable from their first parents. Those edges are removed and
771 then the commits look like single-parent commits that are TREESAME to
772 their parent. This also happens to the commit N, resulting in a history
773 view as follows:
774
775 .-A---M--.
776 / / \
777 I B R
778 \ / /
779 \ / /
780 `---X--'
781
782 In this view, we see all of the important single-parent changes from A,
783 B, and X. We also see the carefully-resolved merge M and the
784 not-so-carefully-resolved merge R. This is usually enough information
785 to determine why the commits A and B "disappeared" from history in the
786 default view. However, there are a few issues with this approach.
787
788 The first issue is performance. Unlike any previous option, the
789 --simplify-merges option requires walking the entire commit history
790 before returning a single result. This can make the option difficult to
791 use for very large repositories.
792
793 The second issue is one of auditing. When many contributors are working
794 on the same repository, it is important which merge commits introduced
795 a change into an important branch. The problematic merge R above is not
796 likely to be the merge commit that was used to merge into an important
797 branch. Instead, the merge N was used to merge R and X into the
798 important branch. This commit may have information about why the change
799 X came to override the changes from A and B in its commit message.
800
801 --show-pulls
802 In addition to the commits shown in the default history, show each
803 merge commit that is not TREESAME to its first parent but is
804 TREESAME to a later parent.
805
806 When a merge commit is included by --show-pulls, the merge is
807 treated as if it "pulled" the change from another branch. When
808 using --show-pulls on this example (and no other options) the
809 resulting graph is:
810
811 I---X---R---N
812
813 Here, the merge commits R and N are included because they pulled
814 the commits X and R into the base branch, respectively. These
815 merges are the reason the commits A and B do not appear in the
816 default history.
817
818 When --show-pulls is paired with --simplify-merges, the graph
819 includes all of the necessary information:
820
821 .-A---M--. N
822 / / \ /
823 I B R
824 \ / /
825 \ / /
826 `---X--'
827
828 Notice that since M is reachable from R, the edge from N to M was
829 simplified away. However, N still appears in the history as an
830 important commit because it "pulled" the change R into the main
831 branch.
832
833 The --simplify-by-decoration option allows you to view only the big
834 picture of the topology of the history, by omitting commits that are
835 not referenced by tags. Commits are marked as !TREESAME (in other
836 words, kept after history simplification rules described above) if (1)
837 they are referenced by tags, or (2) they change the contents of the
838 paths given on the command line. All other commits are marked as
839 TREESAME (subject to be simplified away).
840
841 Commit Ordering
842 By default, the commits are shown in reverse chronological order.
843
844 --date-order
845 Show no parents before all of its children are shown, but otherwise
846 show commits in the commit timestamp order.
847
848 --author-date-order
849 Show no parents before all of its children are shown, but otherwise
850 show commits in the author timestamp order.
851
852 --topo-order
853 Show no parents before all of its children are shown, and avoid
854 showing commits on multiple lines of history intermixed.
855
856 For example, in a commit history like this:
857
858 ---1----2----4----7
859 \ \
860 3----5----6----8---
861
862 where the numbers denote the order of commit timestamps, git
863 rev-list and friends with --date-order show the commits in the
864 timestamp order: 8 7 6 5 4 3 2 1.
865
866 With --topo-order, they would show 8 6 5 3 7 4 2 1 (or 8 7 4 2 6 5
867 3 1); some older commits are shown before newer ones in order to
868 avoid showing the commits from two parallel development track mixed
869 together.
870
871 --reverse
872 Output the commits chosen to be shown (see Commit Limiting section
873 above) in reverse order. Cannot be combined with --walk-reflogs.
874
875 Object Traversal
876 These options are mostly targeted for packing of Git repositories.
877
878 --no-walk[=(sorted|unsorted)]
879 Only show the given commits, but do not traverse their ancestors.
880 This has no effect if a range is specified. If the argument
881 unsorted is given, the commits are shown in the order they were
882 given on the command line. Otherwise (if sorted or no argument was
883 given), the commits are shown in reverse chronological order by
884 commit time. Cannot be combined with --graph.
885
886 --do-walk
887 Overrides a previous --no-walk.
888
889 Commit Formatting
890 --pretty[=<format>], --format=<format>
891 Pretty-print the contents of the commit logs in a given format,
892 where <format> can be one of oneline, short, medium, full, fuller,
893 reference, email, raw, format:<string> and tformat:<string>. When
894 <format> is none of the above, and has %placeholder in it, it acts
895 as if --pretty=tformat:<format> were given.
896
897 See the "PRETTY FORMATS" section for some additional details for
898 each format. When =<format> part is omitted, it defaults to medium.
899
900 Note: you can specify the default pretty format in the repository
901 configuration (see git-config(1)).
902
903 --abbrev-commit
904 Instead of showing the full 40-byte hexadecimal commit object name,
905 show a prefix that names the object uniquely. "--abbrev=<n>" (which
906 also modifies diff output, if it is displayed) option can be used
907 to specify the minimum length of the prefix.
908
909 This should make "--pretty=oneline" a whole lot more readable for
910 people using 80-column terminals.
911
912 --no-abbrev-commit
913 Show the full 40-byte hexadecimal commit object name. This negates
914 --abbrev-commit, either explicit or implied by other options such
915 as "--oneline". It also overrides the log.abbrevCommit variable.
916
917 --oneline
918 This is a shorthand for "--pretty=oneline --abbrev-commit" used
919 together.
920
921 --encoding=<encoding>
922 Commit objects record the character encoding used for the log
923 message in their encoding header; this option can be used to tell
924 the command to re-code the commit log message in the encoding
925 preferred by the user. For non plumbing commands this defaults to
926 UTF-8. Note that if an object claims to be encoded in X and we are
927 outputting in X, we will output the object verbatim; this means
928 that invalid sequences in the original commit may be copied to the
929 output. Likewise, if iconv(3) fails to convert the commit, we will
930 quietly output the original object verbatim.
931
932 --expand-tabs=<n>, --expand-tabs, --no-expand-tabs
933 Perform a tab expansion (replace each tab with enough spaces to
934 fill to the next display column that is multiple of <n>) in the log
935 message before showing it in the output. --expand-tabs is a
936 short-hand for --expand-tabs=8, and --no-expand-tabs is a
937 short-hand for --expand-tabs=0, which disables tab expansion.
938
939 By default, tabs are expanded in pretty formats that indent the log
940 message by 4 spaces (i.e. medium, which is the default, full, and
941 fuller).
942
943 --notes[=<ref>]
944 Show the notes (see git-notes(1)) that annotate the commit, when
945 showing the commit log message. This is the default for git log,
946 git show and git whatchanged commands when there is no --pretty,
947 --format, or --oneline option given on the command line.
948
949 By default, the notes shown are from the notes refs listed in the
950 core.notesRef and notes.displayRef variables (or corresponding
951 environment overrides). See git-config(1) for more details.
952
953 With an optional <ref> argument, use the ref to find the notes to
954 display. The ref can specify the full refname when it begins with
955 refs/notes/; when it begins with notes/, refs/ and otherwise
956 refs/notes/ is prefixed to form a full name of the ref.
957
958 Multiple --notes options can be combined to control which notes are
959 being displayed. Examples: "--notes=foo" will show only notes from
960 "refs/notes/foo"; "--notes=foo --notes" will show both notes from
961 "refs/notes/foo" and from the default notes ref(s).
962
963 --no-notes
964 Do not show notes. This negates the above --notes option, by
965 resetting the list of notes refs from which notes are shown.
966 Options are parsed in the order given on the command line, so e.g.
967 "--notes --notes=foo --no-notes --notes=bar" will only show notes
968 from "refs/notes/bar".
969
970 --show-notes[=<ref>], --[no-]standard-notes
971 These options are deprecated. Use the above --notes/--no-notes
972 options instead.
973
974 --show-signature
975 Check the validity of a signed commit object by passing the
976 signature to gpg --verify and show the output.
977
978 --relative-date
979 Synonym for --date=relative.
980
981 --date=<format>
982 Only takes effect for dates shown in human-readable format, such as
983 when using --pretty. log.date config variable sets a default value
984 for the log command’s --date option. By default, dates are shown in
985 the original time zone (either committer’s or author’s). If -local
986 is appended to the format (e.g., iso-local), the user’s local time
987 zone is used instead.
988
989 --date=relative shows dates relative to the current time, e.g. “2
990 hours ago”. The -local option has no effect for --date=relative.
991
992 --date=local is an alias for --date=default-local.
993
994 --date=iso (or --date=iso8601) shows timestamps in a ISO 8601-like
995 format. The differences to the strict ISO 8601 format are:
996
997 • a space instead of the T date/time delimiter
998
999 • a space between time and time zone
1000
1001 • no colon between hours and minutes of the time zone
1002
1003 --date=iso-strict (or --date=iso8601-strict) shows timestamps in
1004 strict ISO 8601 format.
1005
1006 --date=rfc (or --date=rfc2822) shows timestamps in RFC 2822 format,
1007 often found in email messages.
1008
1009 --date=short shows only the date, but not the time, in YYYY-MM-DD
1010 format.
1011
1012 --date=raw shows the date as seconds since the epoch (1970-01-01
1013 00:00:00 UTC), followed by a space, and then the timezone as an
1014 offset from UTC (a + or - with four digits; the first two are
1015 hours, and the second two are minutes). I.e., as if the timestamp
1016 were formatted with strftime("%s %z")). Note that the -local option
1017 does not affect the seconds-since-epoch value (which is always
1018 measured in UTC), but does switch the accompanying timezone value.
1019
1020 --date=human shows the timezone if the timezone does not match the
1021 current time-zone, and doesn’t print the whole date if that matches
1022 (ie skip printing year for dates that are "this year", but also
1023 skip the whole date itself if it’s in the last few days and we can
1024 just say what weekday it was). For older dates the hour and minute
1025 is also omitted.
1026
1027 --date=unix shows the date as a Unix epoch timestamp (seconds since
1028 1970). As with --raw, this is always in UTC and therefore -local
1029 has no effect.
1030
1031 --date=format:... feeds the format ... to your system strftime,
1032 except for %s, %z, and %Z, which are handled internally. Use
1033 --date=format:%c to show the date in your system locale’s preferred
1034 format. See the strftime manual for a complete list of format
1035 placeholders. When using -local, the correct syntax is
1036 --date=format-local:....
1037
1038 --date=default is the default format, and is similar to
1039 --date=rfc2822, with a few exceptions:
1040
1041 • there is no comma after the day-of-week
1042
1043 • the time zone is omitted when the local time zone is used
1044
1045 --parents
1046 Print also the parents of the commit (in the form "commit parent...
1047 "). Also enables parent rewriting, see History Simplification
1048 above.
1049
1050 --children
1051 Print also the children of the commit (in the form "commit child...
1052 "). Also enables parent rewriting, see History Simplification
1053 above.
1054
1055 --left-right
1056 Mark which side of a symmetric difference a commit is reachable
1057 from. Commits from the left side are prefixed with < and those from
1058 the right with >. If combined with --boundary, those commits are
1059 prefixed with -.
1060
1061 For example, if you have this topology:
1062
1063 y---b---b branch B
1064 / \ /
1065 / .
1066 / / \
1067 o---x---a---a branch A
1068
1069 you would get an output like this:
1070
1071 $ git rev-list --left-right --boundary --pretty=oneline A...B
1072
1073 >bbbbbbb... 3rd on b
1074 >bbbbbbb... 2nd on b
1075 <aaaaaaa... 3rd on a
1076 <aaaaaaa... 2nd on a
1077 -yyyyyyy... 1st on b
1078 -xxxxxxx... 1st on a
1079
1080 --graph
1081 Draw a text-based graphical representation of the commit history on
1082 the left hand side of the output. This may cause extra lines to be
1083 printed in between commits, in order for the graph history to be
1084 drawn properly. Cannot be combined with --no-walk.
1085
1086 This enables parent rewriting, see History Simplification above.
1087
1088 This implies the --topo-order option by default, but the
1089 --date-order option may also be specified.
1090
1091 --show-linear-break[=<barrier>]
1092 When --graph is not used, all history branches are flattened which
1093 can make it hard to see that the two consecutive commits do not
1094 belong to a linear branch. This option puts a barrier in between
1095 them in that case. If <barrier> is specified, it is the string that
1096 will be shown instead of the default one.
1097
1099 If the commit is a merge, and if the pretty-format is not oneline,
1100 email or raw, an additional line is inserted before the Author: line.
1101 This line begins with "Merge: " and the hashes of ancestral commits are
1102 printed, separated by spaces. Note that the listed commits may not
1103 necessarily be the list of the direct parent commits if you have
1104 limited your view of history: for example, if you are only interested
1105 in changes related to a certain directory or file.
1106
1107 There are several built-in formats, and you can define additional
1108 formats by setting a pretty.<name> config option to either another
1109 format name, or a format: string, as described below (see git-
1110 config(1)). Here are the details of the built-in formats:
1111
1112 • oneline
1113
1114 <hash> <title-line>
1115
1116 This is designed to be as compact as possible.
1117
1118 • short
1119
1120 commit <hash>
1121 Author: <author>
1122
1123 <title-line>
1124
1125 • medium
1126
1127 commit <hash>
1128 Author: <author>
1129 Date: <author-date>
1130
1131 <title-line>
1132
1133 <full-commit-message>
1134
1135 • full
1136
1137 commit <hash>
1138 Author: <author>
1139 Commit: <committer>
1140
1141 <title-line>
1142
1143 <full-commit-message>
1144
1145 • fuller
1146
1147 commit <hash>
1148 Author: <author>
1149 AuthorDate: <author-date>
1150 Commit: <committer>
1151 CommitDate: <committer-date>
1152
1153 <title-line>
1154
1155 <full-commit-message>
1156
1157 • reference
1158
1159 <abbrev-hash> (<title-line>, <short-author-date>)
1160
1161 This format is used to refer to another commit in a commit message
1162 and is the same as --pretty='format:%C(auto)%h (%s, %ad)'. By
1163 default, the date is formatted with --date=short unless another
1164 --date option is explicitly specified. As with any format: with
1165 format placeholders, its output is not affected by other options
1166 like --decorate and --walk-reflogs.
1167
1168 • email
1169
1170 From <hash> <date>
1171 From: <author>
1172 Date: <author-date>
1173 Subject: [PATCH] <title-line>
1174
1175 <full-commit-message>
1176
1177 • mboxrd
1178
1179 Like email, but lines in the commit message starting with "From "
1180 (preceded by zero or more ">") are quoted with ">" so they aren’t
1181 confused as starting a new commit.
1182
1183 • raw
1184
1185 The raw format shows the entire commit exactly as stored in the
1186 commit object. Notably, the hashes are displayed in full,
1187 regardless of whether --abbrev or --no-abbrev are used, and parents
1188 information show the true parent commits, without taking grafts or
1189 history simplification into account. Note that this format affects
1190 the way commits are displayed, but not the way the diff is shown
1191 e.g. with git log --raw. To get full object names in a raw diff
1192 format, use --no-abbrev.
1193
1194 • format:<format-string>
1195
1196 The format:<format-string> format allows you to specify which
1197 information you want to show. It works a little bit like printf
1198 format, with the notable exception that you get a newline with %n
1199 instead of \n.
1200
1201 E.g, format:"The author of %h was %an, %ar%nThe title was >>%s<<%n"
1202 would show something like this:
1203
1204 The author of fe6e0ee was Junio C Hamano, 23 hours ago
1205 The title was >>t4119: test autocomputing -p<n> for traditional diff input.<<
1206
1207 The placeholders are:
1208
1209 • Placeholders that expand to a single literal character:
1210
1211 %n
1212 newline
1213
1214 %%
1215 a raw %
1216
1217 %x00
1218 print a byte from a hex code
1219
1220 • Placeholders that affect formatting of later placeholders:
1221
1222 %Cred
1223 switch color to red
1224
1225 %Cgreen
1226 switch color to green
1227
1228 %Cblue
1229 switch color to blue
1230
1231 %Creset
1232 reset color
1233
1234 %C(...)
1235 color specification, as described under Values in the
1236 "CONFIGURATION FILE" section of git-config(1). By default,
1237 colors are shown only when enabled for log output (by
1238 color.diff, color.ui, or --color, and respecting the auto
1239 settings of the former if we are going to a terminal).
1240 %C(auto,...) is accepted as a historical synonym for the
1241 default (e.g., %C(auto,red)). Specifying %C(always,...)
1242 will show the colors even when color is not otherwise
1243 enabled (though consider just using --color=always to
1244 enable color for the whole output, including this format
1245 and anything else git might color). auto alone (i.e.
1246 %C(auto)) will turn on auto coloring on the next
1247 placeholders until the color is switched again.
1248
1249 %m
1250 left (<), right (>) or boundary (-) mark
1251
1252 %w([<w>[,<i1>[,<i2>]]])
1253 switch line wrapping, like the -w option of git-
1254 shortlog(1).
1255
1256 %<(<N>[,trunc|ltrunc|mtrunc])
1257 make the next placeholder take at least N columns, padding
1258 spaces on the right if necessary. Optionally truncate at
1259 the beginning (ltrunc), the middle (mtrunc) or the end
1260 (trunc) if the output is longer than N columns. Note that
1261 truncating only works correctly with N >= 2.
1262
1263 %<|(<N>)
1264 make the next placeholder take at least until Nth columns,
1265 padding spaces on the right if necessary
1266
1267 %>(<N>), %>|(<N>)
1268 similar to %<(<N>), %<|(<N>) respectively, but padding
1269 spaces on the left
1270
1271 %>>(<N>), %>>|(<N>)
1272 similar to %>(<N>), %>|(<N>) respectively, except that if
1273 the next placeholder takes more spaces than given and there
1274 are spaces on its left, use those spaces
1275
1276 %><(<N>), %><|(<N>)
1277 similar to %<(<N>), %<|(<N>) respectively, but padding both
1278 sides (i.e. the text is centered)
1279
1280 • Placeholders that expand to information extracted from the
1281 commit:
1282
1283 %H
1284 commit hash
1285
1286 %h
1287 abbreviated commit hash
1288
1289 %T

1390 committer date, human style (like the --date=human option
1391 of git-rev-list(1))
1392
1393 %d
1394 ref names, like the --decorate option of git-log(1)
1395
1396 %D
1397 ref names without the " (", ")" wrapping.
1398
1399 %(describe[:options])
1400 human-readable name, like git-describe(1); empty string for
1401 undescribable commits. The describe string may be followed
1402 by a colon and zero or more comma-separated options.
1403 Descriptions can be inconsistent when tags are added or
1404 removed at the same time.
1405
1406 • tags[=<bool-value>]: Instead of only considering
1407 annotated tags, consider lightweight tags as well.
1408
1409 • abbrev=<number>: Instead of using the default number of
1410 hexadecimal digits (which will vary according to the
1411 number of objects in the repository with a default of
1412 7) of the abbreviated object name, use <number> digits,
1413 or as many digits as needed to form a unique object
1414 name.
1415
1416 • match=<pattern>: Only consider tags matching the given
1417 glob(7) pattern, excluding the "refs/tags/" prefix.
1418
1419 • exclude=<pattern>: Do not consider tags matching the
1420 given glob(7) pattern, excluding the "refs/tags/"
1421 prefix.
1422
1423 %S
1424 ref name given on the command line by which the commit was
1425 reached (like git log --source), only works with git log
1426
1427 %e
1428 encoding
1429
1430 %s
1431 subject
1432
1433 %f
1434 sanitized subject line, suitable for a filename
1435
1436 %b
1437 body
1438
1439 %B
1440 raw body (unwrapped subject and body)
1441
1442 %N
1443 commit notes
1444
1445 %GG
1446 raw verification message from GPG for a signed commit
1447
1448 %G?
1449 show "G" for a good (valid) signature, "B" for a bad
1450 signature, "U" for a good signature with unknown validity,
1451 "X" for a good signature that has expired, "Y" for a good
1452 signature made by an expired key, "R" for a good signature
1453 made by a revoked key, "E" if the signature cannot be
1454 checked (e.g. missing key) and "N" for no signature
1455
1456 %GS
1457 show the name of the signer for a signed commit
1458
1459 %GK
1460 show the key used to sign a signed commit
1461
1462 %GF
1463 show the fingerprint of the key used to sign a signed
1464 commit
1465
1466 %GP
1467 show the fingerprint of the primary key whose subkey was
1468 used to sign a signed commit
1469
1470 %GT
1471 show the trust level for the key used to sign a signed
1472 commit
1473
1474 %gD
1475 reflog selector, e.g., refs/stash@{1} or refs/stash@{2
1476 minutes ago}; the format follows the rules described for
1477 the -g option. The portion before the @ is the refname as
1478 given on the command line (so git log -g refs/heads/master
1479 would yield refs/heads/master@{0}).
1480
1481 %gd
1482 shortened reflog selector; same as %gD, but the refname
1483 portion is shortened for human readability (so
1484 refs/heads/master becomes just master).
1485
1486 %gn
1487 reflog identity name
1488
1489 %gN
1490 reflog identity name (respecting .mailmap, see git-
1491 shortlog(1) or git-blame(1))
1492
1493 %ge
1494 reflog identity email
1495
1496 %gE
1497 reflog identity email (respecting .mailmap, see git-
1498 shortlog(1) or git-blame(1))
1499
1500 %gs
1501 reflog subject
1502
1503 %(trailers[:options])
1504 display the trailers of the body as interpreted by git-
1505 interpret-trailers(1). The trailers string may be followed
1506 by a colon and zero or more comma-separated options. If any
1507 option is provided multiple times the last occurrence wins.
1508
1509 • key=<key>: only show trailers with specified <key>.
1510 Matching is done case-insensitively and trailing colon
1511 is optional. If option is given multiple times trailer
1512 lines matching any of the keys are shown. This option
1513 automatically enables the only option so that
1514 non-trailer lines in the trailer block are hidden. If
1515 that is not desired it can be disabled with only=false.
1516 E.g., %(trailers:key=Reviewed-by) shows trailer lines
1517 with key Reviewed-by.
1518
1519 • only[=<bool>]: select whether non-trailer lines from
1520 the trailer block should be included.
1521
1522 • separator=<sep>: specify a separator inserted between
1523 trailer lines. When this option is not given each
1524 trailer line is terminated with a line feed character.
1525 The string <sep> may contain the literal formatting
1526 codes described above. To use comma as separator one
1527 must use %x2C as it would otherwise be parsed as next
1528 option. E.g., %(trailers:key=Ticket,separator=%x2C )
1529 shows all trailer lines whose key is "Ticket" separated
1530 by a comma and a space.
1531
1532 • unfold[=<bool>]: make it behave as if
1533 interpret-trailer’s --unfold option was given. E.g.,
1534 %(trailers:only,unfold=true) unfolds and shows all
1535 trailer lines.
1536
1537 • keyonly[=<bool>]: only show the key part of the
1538 trailer.
1539
1540 • valueonly[=<bool>]: only show the value part of the
1541 trailer.
1542
1543 • key_value_separator=<sep>: specify a separator inserted
1544 between trailer lines. When this option is not given
1545 each trailer key-value pair is separated by ": ".
1546 Otherwise it shares the same semantics as
1547 separator=<sep> above.
1548
1549 Note
1550 Some placeholders may depend on other options given to the revision
1551 traversal engine. For example, the %g* reflog options will insert
1552 an empty string unless we are traversing reflog entries (e.g., by
1553 git log -g). The %d and %D placeholders will use the "short"
1554 decoration format if --decorate was not already provided on the
1555 command line.
1556
1557 The boolean options accept an optional value [=<bool-value>]. The
1558 values true, false, on, off etc. are all accepted. See the "boolean"
1559 sub-section in "EXAMPLES" in git-config(1). If a boolean option is
1560 given with no value, it’s enabled.
1561
1562 If you add a + (plus sign) after % of a placeholder, a line-feed is
1563 inserted immediately before the expansion if and only if the
1564 placeholder expands to a non-empty string.
1565
1566 If you add a - (minus sign) after % of a placeholder, all consecutive
1567 line-feeds immediately preceding the expansion are deleted if and only
1568 if the placeholder expands to an empty string.
1569
1570 If you add a ` ` (space) after % of a placeholder, a space is inserted
1571 immediately before the expansion if and only if the placeholder expands
1572 to a non-empty string.
1573
1574 • tformat:
1575
1576 The tformat: format works exactly like format:, except that it
1577 provides "terminator" semantics instead of "separator" semantics.
1578 In other words, each commit has the message terminator character
1579 (usually a newline) appended, rather than a separator placed
1580 between entries. This means that the final entry of a single-line
1581 format will be properly terminated with a new line, just as the
1582 "oneline" format does. For example:
1583
1584 $ git log -2 --pretty=format:%h 4da45bef \
1585 | perl -pe '$_ .= " -- NO NEWLINE\n" unless /\n/'
1586 4da45be
1587 7134973 -- NO NEWLINE
1588
1589 $ git log -2 --pretty=tformat:%h 4da45bef \
1590 | perl -pe '$_ .= " -- NO NEWLINE\n" unless /\n/'
1591 4da45be
1592 7134973
1593
1594 In addition, any unrecognized string that has a % in it is
1595 interpreted as if it has tformat: in front of it. For example,
1596 these two are equivalent:
1597
1598 $ git log -2 --pretty=tformat:%h 4da45bef
1599 $ git log -2 --pretty=%h 4da45bef
1600
1602 By default, git log does not generate any diff output. The options
1603 below can be used to show the changes made by each commit.
1604
1605 Note that unless one of --diff-merges variants (including short -m, -c,
1606 and --cc options) is explicitly given, merge commits will not show a
1607 diff, even if a diff format like --patch is selected, nor will they
1608 match search options like -S. The exception is when --first-parent is
1609 in use, in which case first-parent is the default format.
1610
1611 -p, -u, --patch
1612 Generate patch (see section on generating patches).
1613
1614 -s, --no-patch
1615 Suppress diff output. Useful for commands like git show that show
1616 the patch by default, or to cancel the effect of --patch.
1617
1618 --diff-merges=(off|none|on|first-parent|1|separate|m|combined|c|dense-combined|cc|remerge|r),
1619 --no-diff-merges
1620 Specify diff format to be used for merge commits. Default is `off`
1621 unless --first-parent is in use, in which case first-parent is the
1622 default.
1623
1624 --diff-merges=(off|none), --no-diff-merges
1625 Disable output of diffs for merge commits. Useful to override
1626 implied value.
1627
1628 --diff-merges=on, --diff-merges=m, -m
1629 This option makes diff output for merge commits to be shown in
1630 the default format. -m will produce the output only if -p is
1631 given as well. The default format could be changed using
1632 log.diffMerges configuration parameter, which default value is
1633 separate.
1634
1635 --diff-merges=first-parent, --diff-merges=1
1636 This option makes merge commits show the full diff with respect
1637 to the first parent only.
1638
1639 --diff-merges=separate
1640 This makes merge commits show the full diff with respect to
1641 each of the parents. Separate log entry and diff is generated
1642 for each parent.
1643
1644 --diff-merges=remerge, --diff-merges=r, --remerge-diff
1645 With this option, two-parent merge commits are remerged to
1646 create a temporary tree object — potentially containing files
1647 with conflict markers and such. A diff is then shown between
1648 that temporary tree and the actual merge commit.
1649
1650 The output emitted when this option is used is subject to
1651 change, and so is its interaction with other options (unless
1652 explicitly documented).
1653
1654 --diff-merges=combined, --diff-merges=c, -c
1655 With this option, diff output for a merge commit shows the
1656 differences from each of the parents to the merge result
1657 simultaneously instead of showing pairwise diff between a
1658 parent and the result one at a time. Furthermore, it lists only
1659 files which were modified from all parents. -c implies -p.
1660
1661 --diff-merges=dense-combined, --diff-merges=cc, --cc
1662 With this option the output produced by --diff-merges=combined
1663 is further compressed by omitting uninteresting hunks whose
1664 contents in the parents have only two variants and the merge
1665 result picks one of them without modification. --cc implies
1666 -p.
1667
1668 --combined-all-paths
1669 This flag causes combined diffs (used for merge commits) to list
1670 the name of the file from all parents. It thus only has effect when
1671 --diff-merges=[dense-]combined is in use, and is likely only useful
1672 if filename changes are detected (i.e. when either rename or copy
1673 detection have been requested).
1674
1675 -U<n>, --unified=<n>
1676 Generate diffs with <n> lines of context instead of the usual
1677 three. Implies --patch.
1678
1679 --output=<file>
1680 Output to a specific file instead of stdout.
1681
1682 --output-indicator-new=<char>, --output-indicator-old=<char>,
1683 --output-indicator-context=<char>
1684 Specify the character used to indicate new, old or context lines in
1685 the generated patch. Normally they are +, - and ' ' respectively.
1686
1687 --raw
1688 For each commit, show a summary of changes using the raw diff
1689 format. See the "RAW OUTPUT FORMAT" section of git-diff(1). This is
1690 different from showing the log itself in raw format, which you can
1691 achieve with --format=raw.
1692
1693 --patch-with-raw
1694 Synonym for -p --raw.
1695
1696 -t
1697 Show the tree objects in the diff output.
1698
1699 --indent-heuristic
1700 Enable the heuristic that shifts diff hunk boundaries to make
1701 patches easier to read. This is the default.
1702
1703 --no-indent-heuristic
1704 Disable the indent heuristic.
1705
1706 --minimal
1707 Spend extra time to make sure the smallest possible diff is
1708 produced.
1709
1710 --patience
1711 Generate a diff using the "patience diff" algorithm.
1712
1713 --histogram
1714 Generate a diff using the "histogram diff" algorithm.
1715
1716 --anchored=<text>
1717 Generate a diff using the "anchored diff" algorithm.
1718
1719 This option may be specified more than once.
1720
1721 If a line exists in both the source and destination, exists only
1722 once, and starts with this text, this algorithm attempts to prevent
1723 it from appearing as a deletion or addition in the output. It uses
1724 the "patience diff" algorithm internally.
1725
1726 --diff-algorithm={patience|minimal|histogram|myers}
1727 Choose a diff algorithm. The variants are as follows:
1728
1729 default, myers
1730 The basic greedy diff algorithm. Currently, this is the
1731 default.
1732
1733 minimal
1734 Spend extra time to make sure the smallest possible diff is
1735 produced.
1736
1737 patience
1738 Use "patience diff" algorithm when generating patches.
1739
1740 histogram
1741 This algorithm extends the patience algorithm to "support
1742 low-occurrence common elements".
1743
1744 For instance, if you configured the diff.algorithm variable to a
1745 non-default value and want to use the default one, then you have to
1746 use --diff-algorithm=default option.
1747
1748 --stat[=<width>[,<name-width>[,<count>]]]
1749 Generate a diffstat. By default, as much space as necessary will be
1750 used for the filename part, and the rest for the graph part.
1751 Maximum width defaults to terminal width, or 80 columns if not
1752 connected to a terminal, and can be overridden by <width>. The
1753 width of the filename part can be limited by giving another width
1754 <name-width> after a comma. The width of the graph part can be
1755 limited by using --stat-graph-width=<width> (affects all commands
1756 generating a stat graph) or by setting diff.statGraphWidth=<width>
1757 (does not affect git format-patch). By giving a third parameter
1758 <count>, you can limit the output to the first <count> lines,
1759 followed by ... if there are more.
1760
1761 These parameters can also be set individually with
1762 --stat-width=<width>, --stat-name-width=<name-width> and
1763 --stat-count=<count>.
1764
1765 --compact-summary
1766 Output a condensed summary of extended header information such as
1767 file creations or deletions ("new" or "gone", optionally "+l" if
1768 it’s a symlink) and mode changes ("+x" or "-x" for adding or
1769 removing executable bit respectively) in diffstat. The information
1770 is put between the filename part and the graph part. Implies
1771 --stat.
1772
1773 --numstat
1774 Similar to --stat, but shows number of added and deleted lines in
1775 decimal notation and pathname without abbreviation, to make it more
1776 machine friendly. For binary files, outputs two - instead of saying
1777 0 0.
1778
1779 --shortstat
1780 Output only the last line of the --stat format containing total
1781 number of modified files, as well as number of added and deleted
1782 lines.
1783
1784 -X[<param1,param2,...>], --dirstat[=<param1,param2,...>]
1785 Output the distribution of relative amount of changes for each
1786 sub-directory. The behavior of --dirstat can be customized by
1787 passing it a comma separated list of parameters. The defaults are
1788 controlled by the diff.dirstat configuration variable (see git-
1789 config(1)). The following parameters are available:
1790
1791 changes
1792 Compute the dirstat numbers by counting the lines that have
1793 been removed from the source, or added to the destination. This
1794 ignores the amount of pure code movements within a file. In
1795 other words, rearranging lines in a file is not counted as much
1796 as other changes. This is the default behavior when no
1797 parameter is given.
1798
1799 lines
1800 Compute the dirstat numbers by doing the regular line-based
1801 diff analysis, and summing the removed/added line counts. (For
1802 binary files, count 64-byte chunks instead, since binary files
1803 have no natural concept of lines). This is a more expensive
1804 --dirstat behavior than the changes behavior, but it does count
1805 rearranged lines within a file as much as other changes. The
1806 resulting output is consistent with what you get from the other
1807 --*stat options.
1808
1809 files
1810 Compute the dirstat numbers by counting the number of files
1811 changed. Each changed file counts equally in the dirstat
1812 analysis. This is the computationally cheapest --dirstat
1813 behavior, since it does not have to look at the file contents
1814 at all.
1815
1816 cumulative
1817 Count changes in a child directory for the parent directory as
1818 well. Note that when using cumulative, the sum of the
1819 percentages reported may exceed 100%. The default
1820 (non-cumulative) behavior can be specified with the
1821 noncumulative parameter.
1822
1823 <limit>
1824 An integer parameter specifies a cut-off percent (3% by
1825 default). Directories contributing less than this percentage of
1826 the changes are not shown in the output.
1827
1828 Example: The following will count changed files, while ignoring
1829 directories with less than 10% of the total amount of changed
1830 files, and accumulating child directory counts in the parent
1831 directories: --dirstat=files,10,cumulative.
1832
1833 --cumulative
1834 Synonym for --dirstat=cumulative
1835
1836 --dirstat-by-file[=<param1,param2>...]
1837 Synonym for --dirstat=files,param1,param2...
1838
1839 --summary
1840 Output a condensed summary of extended header information such as
1841 creations, renames and mode changes.
1842
1843 --patch-with-stat
1844 Synonym for -p --stat.
1845
1846 -z
1847 Separate the commits with NULs instead of with new newlines.
1848
1849 Also, when --raw or --numstat has been given, do not munge
1850 pathnames and use NULs as output field terminators.
1851
1852 Without this option, pathnames with "unusual" characters are quoted
1853 as explained for the configuration variable core.quotePath (see
1854 git-config(1)).
1855
1856 --name-only
1857 Show only names of changed files. The file names are often encoded
1858 in UTF-8. For more information see the discussion about encoding in
1859 the git-log(1) manual page.
1860
1861 --name-status
1862 Show only names and status of changed files. See the description of
1863 the --diff-filter option on what the status letters mean. Just like
1864 --name-only the file names are often encoded in UTF-8.
1865
1866 --submodule[=<format>]
1867 Specify how differences in submodules are shown. When specifying
1868 --submodule=short the short format is used. This format just shows
1869 the names of the commits at the beginning and end of the range.
1870 When --submodule or --submodule=log is specified, the log format is
1871 used. This format lists the commits in the range like git-
1872 submodule(1) summary does. When --submodule=diff is specified, the
1873 diff format is used. This format shows an inline diff of the
1874 changes in the submodule contents between the commit range.
1875 Defaults to diff.submodule or the short format if the config option
1876 is unset.
1877
1878 --color[=<when>]
1879 Show colored diff. --color (i.e. without =<when>) is the same as
1880 --color=always. <when> can be one of always, never, or auto.
1881
1882 --no-color
1883 Turn off colored diff. It is the same as --color=never.
1884
1885 --color-moved[=<mode>]
1886 Moved lines of code are colored differently. The <mode> defaults to
1887 no if the option is not given and to zebra if the option with no
1888 mode is given. The mode must be one of:
1889
1890 no
1891 Moved lines are not highlighted.
1892
1893 default
1894 Is a synonym for zebra. This may change to a more sensible mode
1895 in the future.
1896
1897 plain
1898 Any line that is added in one location and was removed in
1899 another location will be colored with color.diff.newMoved.
1900 Similarly color.diff.oldMoved will be used for removed lines
1901 that are added somewhere else in the diff. This mode picks up
1902 any moved line, but it is not very useful in a review to
1903 determine if a block of code was moved without permutation.
1904
1905 blocks
1906 Blocks of moved text of at least 20 alphanumeric characters are
1907 detected greedily. The detected blocks are painted using either
1908 the color.diff.{old,new}Moved color. Adjacent blocks cannot be
1909 told apart.
1910
1911 zebra
1912 Blocks of moved text are detected as in blocks mode. The blocks
1913 are painted using either the color.diff.{old,new}Moved color or
1914 color.diff.{old,new}MovedAlternative. The change between the
1915 two colors indicates that a new block was detected.
1916
1917 dimmed-zebra
1918 Similar to zebra, but additional dimming of uninteresting parts
1919 of moved code is performed. The bordering lines of two adjacent
1920 blocks are considered interesting, the rest is uninteresting.
1921 dimmed_zebra is a deprecated synonym.
1922
1923 --no-color-moved
1924 Turn off move detection. This can be used to override configuration
1925 settings. It is the same as --color-moved=no.
1926
1927 --color-moved-ws=<modes>
1928 This configures how whitespace is ignored when performing the move
1929 detection for --color-moved. These modes can be given as a comma
1930 separated list:
1931
1932 no
1933 Do not ignore whitespace when performing move detection.
1934
1935 ignore-space-at-eol
1936 Ignore changes in whitespace at EOL.
1937
1938 ignore-space-change
1939 Ignore changes in amount of whitespace. This ignores whitespace
1940 at line end, and considers all other sequences of one or more
1941 whitespace characters to be equivalent.
1942
1943 ignore-all-space
1944 Ignore whitespace when comparing lines. This ignores
1945 differences even if one line has whitespace where the other
1946 line has none.
1947
1948 allow-indentation-change
1949 Initially ignore any whitespace in the move detection, then
1950 group the moved code blocks only into a block if the change in
1951 whitespace is the same per line. This is incompatible with the
1952 other modes.
1953
1954 --no-color-moved-ws
1955 Do not ignore whitespace when performing move detection. This can
1956 be used to override configuration settings. It is the same as
1957 --color-moved-ws=no.
1958
1959 --word-diff[=<mode>]
1960 Show a word diff, using the <mode> to delimit changed words. By
1961 default, words are delimited by whitespace; see --word-diff-regex
1962 below. The <mode> defaults to plain, and must be one of:
1963
1964 color
1965 Highlight changed words using only colors. Implies --color.
1966
1967 plain
1968 Show words as [-removed-] and {+added+}. Makes no attempts to
1969 escape the delimiters if they appear in the input, so the
1970 output may be ambiguous.
1971
1972 porcelain
1973 Use a special line-based format intended for script
1974 consumption. Added/removed/unchanged runs are printed in the
1975 usual unified diff format, starting with a +/-/` ` character at
1976 the beginning of the line and extending to the end of the line.
1977 Newlines in the input are represented by a tilde ~ on a line of
1978 its own.
1979
1980 none
1981 Disable word diff again.
1982
1983 Note that despite the name of the first mode, color is used to
1984 highlight the changed parts in all modes if enabled.
1985
1986 --word-diff-regex=<regex>
1987 Use <regex> to decide what a word is, instead of considering runs
1988 of non-whitespace to be a word. Also implies --word-diff unless it
1989 was already enabled.
1990
1991 Every non-overlapping match of the <regex> is considered a word.
1992 Anything between these matches is considered whitespace and
1993 ignored(!) for the purposes of finding differences. You may want to
1994 append |[^[:space:]] to your regular expression to make sure that
1995 it matches all non-whitespace characters. A match that contains a
1996 newline is silently truncated(!) at the newline.
1997
1998 For example, --word-diff-regex=. will treat each character as a
1999 word and, correspondingly, show differences character by character.
2000
2001 The regex can also be set via a diff driver or configuration
2002 option, see gitattributes(5) or git-config(1). Giving it explicitly
2003 overrides any diff driver or configuration setting. Diff drivers
2004 override configuration settings.
2005
2006 --color-words[=<regex>]
2007 Equivalent to --word-diff=color plus (if a regex was specified)
2008 --word-diff-regex=<regex>.
2009
2010 --no-renames
2011 Turn off rename detection, even when the configuration file gives
2012 the default to do so.
2013
2014 --[no-]rename-empty
2015 Whether to use empty blobs as rename source.
2016
2017 --check
2018 Warn if changes introduce conflict markers or whitespace errors.
2019 What are considered whitespace errors is controlled by
2020 core.whitespace configuration. By default, trailing whitespaces
2021 (including lines that consist solely of whitespaces) and a space
2022 character that is immediately followed by a tab character inside
2023 the initial indent of the line are considered whitespace errors.
2024 Exits with non-zero status if problems are found. Not compatible
2025 with --exit-code.
2026
2027 --ws-error-highlight=<kind>
2028 Highlight whitespace errors in the context, old or new lines of the
2029 diff. Multiple values are separated by comma, none resets previous
2030 values, default reset the list to new and all is a shorthand for
2031 old,new,context. When this option is not given, and the
2032 configuration variable diff.wsErrorHighlight is not set, only
2033 whitespace errors in new lines are highlighted. The whitespace
2034 errors are colored with color.diff.whitespace.
2035
2036 --full-index
2037 Instead of the first handful of characters, show the full pre- and
2038 post-image blob object names on the "index" line when generating
2039 patch format output.
2040
2041 --binary
2042 In addition to --full-index, output a binary diff that can be
2043 applied with git-apply. Implies --patch.
2044
2045 --abbrev[=<n>]
2046 Instead of showing the full 40-byte hexadecimal object name in
2047 diff-raw format output and diff-tree header lines, show the
2048 shortest prefix that is at least <n> hexdigits long that uniquely
2049 refers the object. In diff-patch output format, --full-index takes
2050 higher precedence, i.e. if --full-index is specified, full blob
2051 names will be shown regardless of --abbrev. Non default number of
2052 digits can be specified with --abbrev=<n>.
2053
2054 -B[<n>][/<m>], --break-rewrites[=[<n>][/<m>]]
2055 Break complete rewrite changes into pairs of delete and create.
2056 This serves two purposes:
2057
2058 It affects the way a change that amounts to a total rewrite of a
2059 file not as a series of deletion and insertion mixed together with
2060 a very few lines that happen to match textually as the context, but
2061 as a single deletion of everything old followed by a single
2062 insertion of everything new, and the number m controls this aspect
2063 of the -B option (defaults to 60%). -B/70% specifies that less
2064 than 30% of the original should remain in the result for Git to
2065 consider it a total rewrite (i.e. otherwise the resulting patch
2066 will be a series of deletion and insertion mixed together with
2067 context lines).
2068
2069 When used with -M, a totally-rewritten file is also considered as
2070 the source of a rename (usually -M only considers a file that
2071 disappeared as the source of a rename), and the number n controls
2072 this aspect of the -B option (defaults to 50%). -B20% specifies
2073 that a change with addition and deletion compared to 20% or more of
2074 the file’s size are eligible for being picked up as a possible
2075 source of a rename to another file.
2076
2077 -M[<n>], --find-renames[=<n>]
2078 If generating diffs, detect and report renames for each commit. For
2079 following files across renames while traversing history, see
2080 --follow. If n is specified, it is a threshold on the similarity
2081 index (i.e. amount of addition/deletions compared to the file’s
2082 size). For example, -M90% means Git should consider a delete/add
2083 pair to be a rename if more than 90% of the file hasn’t changed.
2084 Without a % sign, the number is to be read as a fraction, with a
2085 decimal point before it. I.e., -M5 becomes 0.5, and is thus the
2086 same as -M50%. Similarly, -M05 is the same as -M5%. To limit
2087 detection to exact renames, use -M100%. The default similarity
2088 index is 50%.
2089
2090 -C[<n>], --find-copies[=<n>]
2091 Detect copies as well as renames. See also --find-copies-harder. If
2092 n is specified, it has the same meaning as for -M<n>.
2093
2094 --find-copies-harder
2095 For performance reasons, by default, -C option finds copies only if
2096 the original file of the copy was modified in the same changeset.
2097 This flag makes the command inspect unmodified files as candidates
2098 for the source of copy. This is a very expensive operation for
2099 large projects, so use it with caution. Giving more than one -C
2100 option has the same effect.
2101
2102 -D, --irreversible-delete
2103 Omit the preimage for deletes, i.e. print only the header but not
2104 the diff between the preimage and /dev/null. The resulting patch is
2105 not meant to be applied with patch or git apply; this is solely for
2106 people who want to just concentrate on reviewing the text after the
2107 change. In addition, the output obviously lacks enough information
2108 to apply such a patch in reverse, even manually, hence the name of
2109 the option.
2110
2111 When used together with -B, omit also the preimage in the deletion
2112 part of a delete/create pair.
2113
2114 -l<num>
2115 The -M and -C options involve some preliminary steps that can
2116 detect subsets of renames/copies cheaply, followed by an exhaustive
2117 fallback portion that compares all remaining unpaired destinations
2118 to all relevant sources. (For renames, only remaining unpaired
2119 sources are relevant; for copies, all original sources are
2120 relevant.) For N sources and destinations, this exhaustive check is
2121 O(N^2). This option prevents the exhaustive portion of rename/copy
2122 detection from running if the number of source/destination files
2123 involved exceeds the specified number. Defaults to
2124 diff.renameLimit. Note that a value of 0 is treated as unlimited.
2125
2126 --diff-filter=[(A|C|D|M|R|T|U|X|B)...[*]]
2127 Select only files that are Added (A), Copied (C), Deleted (D),
2128 Modified (M), Renamed (R), have their type (i.e. regular file,
2129 symlink, submodule, ...) changed (T), are Unmerged (U), are Unknown
2130 (X), or have had their pairing Broken (B). Any combination of the
2131 filter characters (including none) can be used. When *
2132 (All-or-none) is added to the combination, all paths are selected
2133 if there is any file that matches other criteria in the comparison;
2134 if there is no file that matches other criteria, nothing is
2135 selected.
2136
2137 Also, these upper-case letters can be downcased to exclude. E.g.
2138 --diff-filter=ad excludes added and deleted paths.
2139
2140 Note that not all diffs can feature all types. For instance, copied
2141 and renamed entries cannot appear if detection for those types is
2142 disabled.
2143
2144 -S<string>
2145 Look for differences that change the number of occurrences of the
2146 specified string (i.e. addition/deletion) in a file. Intended for
2147 the scripter’s use.
2148
2149 It is useful when you’re looking for an exact block of code (like a
2150 struct), and want to know the history of that block since it first
2151 came into being: use the feature iteratively to feed the
2152 interesting block in the preimage back into -S, and keep going
2153 until you get the very first version of the block.
2154
2155 Binary files are searched as well.
2156
2157 -G<regex>
2158 Look for differences whose patch text contains added/removed lines
2159 that match <regex>.
2160
2161 To illustrate the difference between -S<regex> --pickaxe-regex and
2162 -G<regex>, consider a commit with the following diff in the same
2163 file:
2164
2165 + return frotz(nitfol, two->ptr, 1, 0);
2166 ...
2167 - hit = frotz(nitfol, mf2.ptr, 1, 0);
2168
2169 While git log -G"frotz\(nitfol" will show this commit, git log
2170 -S"frotz\(nitfol" --pickaxe-regex will not (because the number of
2171 occurrences of that string did not change).
2172
2173 Unless --text is supplied patches of binary files without a
2174 textconv filter will be ignored.
2175
2176 See the pickaxe entry in gitdiffcore(7) for more information.
2177
2178 --find-object=<object-id>
2179 Look for differences that change the number of occurrences of the
2180 specified object. Similar to -S, just the argument is different in
2181 that it doesn’t search for a specific string but for a specific
2182 object id.
2183
2184 The object can be a blob or a submodule commit. It implies the -t
2185 option in git-log to also find trees.
2186
2187 --pickaxe-all
2188 When -S or -G finds a change, show all the changes in that
2189 changeset, not just the files that contain the change in <string>.
2190
2191 --pickaxe-regex
2192 Treat the <string> given to -S as an extended POSIX regular
2193 expression to match.
2194
2195 -O<orderfile>
2196 Control the order in which files appear in the output. This
2197 overrides the diff.orderFile configuration variable (see git-
2198 config(1)). To cancel diff.orderFile, use -O/dev/null.
2199
2200 The output order is determined by the order of glob patterns in
2201 <orderfile>. All files with pathnames that match the first pattern
2202 are output first, all files with pathnames that match the second
2203 pattern (but not the first) are output next, and so on. All files
2204 with pathnames that do not match any pattern are output last, as if
2205 there was an implicit match-all pattern at the end of the file. If
2206 multiple pathnames have the same rank (they match the same pattern
2207 but no earlier patterns), their output order relative to each other
2208 is the normal order.
2209
2210 <orderfile> is parsed as follows:
2211
2212 • Blank lines are ignored, so they can be used as separators for
2213 readability.
2214
2215 • Lines starting with a hash ("#") are ignored, so they can be
2216 used for comments. Add a backslash ("\") to the beginning of
2217 the pattern if it starts with a hash.
2218
2219 • Each other line contains a single pattern.
2220
2221 Patterns have the same syntax and semantics as patterns used for
2222 fnmatch(3) without the FNM_PATHNAME flag, except a pathname also
2223 matches a pattern if removing any number of the final pathname
2224 components matches the pattern. For example, the pattern "foo*bar"
2225 matches "fooasdfbar" and "foo/bar/baz/asdf" but not "foobarx".
2226
2227 --skip-to=<file>, --rotate-to=<file>
2228 Discard the files before the named <file> from the output (i.e.
2229 skip to), or move them to the end of the output (i.e. rotate to).
2230 These were invented primarily for use of the git difftool command,
2231 and may not be very useful otherwise.
2232
2233 -R
2234 Swap two inputs; that is, show differences from index or on-disk
2235 file to tree contents.
2236
2237 --relative[=<path>], --no-relative
2238 When run from a subdirectory of the project, it can be told to
2239 exclude changes outside the directory and show pathnames relative
2240 to it with this option. When you are not in a subdirectory (e.g. in
2241 a bare repository), you can name which subdirectory to make the
2242 output relative to by giving a <path> as an argument.
2243 --no-relative can be used to countermand both diff.relative config
2244 option and previous --relative.
2245
2246 -a, --text
2247 Treat all files as text.
2248
2249 --ignore-cr-at-eol
2250 Ignore carriage-return at the end of line when doing a comparison.
2251
2252 --ignore-space-at-eol
2253 Ignore changes in whitespace at EOL.
2254
2255 -b, --ignore-space-change
2256 Ignore changes in amount of whitespace. This ignores whitespace at
2257 line end, and considers all other sequences of one or more
2258 whitespace characters to be equivalent.
2259
2260 -w, --ignore-all-space
2261 Ignore whitespace when comparing lines. This ignores differences
2262 even if one line has whitespace where the other line has none.
2263
2264 --ignore-blank-lines
2265 Ignore changes whose lines are all blank.
2266
2267 -I<regex>, --ignore-matching-lines=<regex>
2268 Ignore changes whose all lines match <regex>. This option may be
2269 specified more than once.
2270
2271 --inter-hunk-context=<lines>
2272 Show the context between diff hunks, up to the specified number of
2273 lines, thereby fusing hunks that are close to each other. Defaults
2274 to diff.interHunkContext or 0 if the config option is unset.
2275
2276 -W, --function-context
2277 Show whole function as context lines for each change. The function
2278 names are determined in the same way as git diff works out patch
2279 hunk headers (see Defining a custom hunk-header in
2280 gitattributes(5)).
2281
2282 --ext-diff
2283 Allow an external diff helper to be executed. If you set an
2284 external diff driver with gitattributes(5), you need to use this
2285 option with git-log(1) and friends.
2286
2287 --no-ext-diff
2288 Disallow external diff drivers.
2289
2290 --textconv, --no-textconv
2291 Allow (or disallow) external text conversion filters to be run when
2292 comparing binary files. See gitattributes(5) for details. Because
2293 textconv filters are typically a one-way conversion, the resulting
2294 diff is suitable for human consumption, but cannot be applied. For
2295 this reason, textconv filters are enabled by default only for git-
2296 diff(1) and git-log(1), but not for git-format-patch(1) or diff
2297 plumbing commands.
2298
2299 --ignore-submodules[=<when>]
2300 Ignore changes to submodules in the diff generation. <when> can be
2301 either "none", "untracked", "dirty" or "all", which is the default.
2302 Using "none" will consider the submodule modified when it either
2303 contains untracked or modified files or its HEAD differs from the
2304 commit recorded in the superproject and can be used to override any
2305 settings of the ignore option in git-config(1) or gitmodules(5).
2306 When "untracked" is used submodules are not considered dirty when
2307 they only contain untracked content (but they are still scanned for
2308 modified content). Using "dirty" ignores all changes to the work
2309 tree of submodules, only changes to the commits stored in the
2310 superproject are shown (this was the behavior until 1.7.0). Using
2311 "all" hides all changes to submodules.
2312
2313 --src-prefix=<prefix>
2314 Show the given source prefix instead of "a/".
2315
2316 --dst-prefix=<prefix>
2317 Show the given destination prefix instead of "b/".
2318
2319 --no-prefix
2320 Do not show any source or destination prefix.
2321
2322 --line-prefix=<prefix>
2323 Prepend an additional prefix to every line of output.
2324
2325 --ita-invisible-in-index
2326 By default entries added by "git add -N" appear as an existing
2327 empty file in "git diff" and a new file in "git diff --cached".
2328 This option makes the entry appear as a new file in "git diff" and
2329 non-existent in "git diff --cached". This option could be reverted
2330 with --ita-visible-in-index. Both options are experimental and
2331 could be removed in future.
2332
2333 For more detailed explanation on these common options, see also
2334 gitdiffcore(7).
2335
2337 Running git-diff(1), git-log(1), git-show(1), git-diff-index(1), git-
2338 diff-tree(1), or git-diff-files(1) with the -p option produces patch
2339 text. You can customize the creation of patch text via the
2340 GIT_EXTERNAL_DIFF and the GIT_DIFF_OPTS environment variables (see
2341 git(1)), and the diff attribute (see gitattributes(5)).
2342
2343 What the -p option produces is slightly different from the traditional
2344 diff format:
2345
2346 1. It is preceded with a "git diff" header that looks like this:
2347
2348 diff --git a/file1 b/file2
2349
2350 The a/ and b/ filenames are the same unless rename/copy is
2351 involved. Especially, even for a creation or a deletion, /dev/null
2352 is not used in place of the a/ or b/ filenames.
2353
2354 When rename/copy is involved, file1 and file2 show the name of the
2355 source file of the rename/copy and the name of the file that
2356 rename/copy produces, respectively.
2357
2358 2. It is followed by one or more extended header lines:
2359
2360 old mode <mode>
2361 new mode <mode>
2362 deleted file mode <mode>
2363 new file mode <mode>
2364 copy from <path>
2365 copy to <path>
2366 rename from <path>
2367 rename to <path>
2368 similarity index <number>
2369 dissimilarity index <number>
2370 index <hash>..<hash> <mode>
2371
2372 File modes are printed as 6-digit octal numbers including the file
2373 type and file permission bits.
2374
2375 Path names in extended headers do not include the a/ and b/
2376 prefixes.
2377
2378 The similarity index is the percentage of unchanged lines, and the
2379 dissimilarity index is the percentage of changed lines. It is a
2380 rounded down integer, followed by a percent sign. The similarity
2381 index value of 100% is thus reserved for two equal files, while
2382 100% dissimilarity means that no line from the old file made it
2383 into the new one.
2384
2385 The index line includes the blob object names before and after the
2386 change. The <mode> is included if the file mode does not change;
2387 otherwise, separate lines indicate the old and the new mode.
2388
2389 3. Pathnames with "unusual" characters are quoted as explained for the
2390 configuration variable core.quotePath (see git-config(1)).
2391
2392 4. All the file1 files in the output refer to files before the commit,
2393 and all the file2 files refer to files after the commit. It is
2394 incorrect to apply each change to each file sequentially. For
2395 example, this patch will swap a and b:
2396
2397 diff --git a/a b/b
2398 rename from a
2399 rename to b
2400 diff --git a/b b/a
2401 rename from b
2402 rename to a
2403
2404 5. Hunk headers mention the name of the function to which the hunk
2405 applies. See "Defining a custom hunk-header" in gitattributes(5)
2406 for details of how to tailor to this to specific languages.
2407
2409 Any diff-generating command can take the -c or --cc option to produce a
2410 combined diff when showing a merge. This is the default format when
2411 showing merges with git-diff(1) or git-show(1). Note also that you can
2412 give suitable --diff-merges option to any of these commands to force
2413 generation of diffs in specific format.
2414
2415 A "combined diff" format looks like this:
2416
2417 diff --combined describe.c
2418 index fabadb8,cc95eb0..4866510
2419 --- a/describe.c
2420 +++ b/describe.c
2421 @@@ -98,20 -98,12 +98,20 @@@
2422 return (a_date > b_date) ? -1 : (a_date == b_date) ? 0 : 1;
2423 }
2424
2425 - static void describe(char *arg)
2426 -static void describe(struct commit *cmit, int last_one)
2427 ++static void describe(char *arg, int last_one)
2428 {
2429 + unsigned char sha1[20];
2430 + struct commit *cmit;
2431 struct commit_list *list;
2432 static int initialized = 0;
2433 struct commit_name *n;
2434
2435 + if (get_sha1(arg, sha1) < 0)
2436 + usage(describe_usage);
2437 + cmit = lookup_commit_reference(sha1);
2438 + if (!cmit)
2439 + usage(describe_usage);
2440 +
2441 if (!initialized) {
2442 initialized = 1;
2443 for_each_ref(get_name);
2444
2445 1. It is preceded with a "git diff" header, that looks like this (when
2446 the -c option is used):
2447
2448 diff --combined file
2449
2450 or like this (when the --cc option is used):
2451
2452 diff --cc file
2453
2454 2. It is followed by one or more extended header lines (this example
2455 shows a merge with two parents):
2456
2457 index <hash>,<hash>..<hash>
2458 mode <mode>,<mode>..<mode>
2459 new file mode <mode>
2460 deleted file mode <mode>,<mode>
2461
2462 The mode <mode>,<mode>..<mode> line appears only if at least one of
2463 the <mode> is different from the rest. Extended headers with
2464 information about detected contents movement (renames and copying
2465 detection) are designed to work with diff of two <tree-ish> and are
2466 not used by combined diff format.
2467
2468 3. It is followed by two-line from-file/to-file header
2469
2470 --- a/file
2471 +++ b/file
2472
2473 Similar to two-line header for traditional unified diff format,
2474 /dev/null is used to signal created or deleted files.
2475
2476 However, if the --combined-all-paths option is provided, instead of
2477 a two-line from-file/to-file you get a N+1 line from-file/to-file
2478 header, where N is the number of parents in the merge commit
2479
2480 --- a/file
2481 --- a/file
2482 --- a/file
2483 +++ b/file
2484
2485 This extended format can be useful if rename or copy detection is
2486 active, to allow you to see the original name of the file in
2487 different parents.
2488
2489 4. Chunk header format is modified to prevent people from accidentally
2490 feeding it to patch -p1. Combined diff format was created for
2491 review of merge commit changes, and was not meant to be applied.
2492 The change is similar to the change in the extended index header:
2493
2494 @@@ <from-file-range> <from-file-range> <to-file-range> @@@
2495
2496 There are (number of parents + 1) @ characters in the chunk header
2497 for combined diff format.
2498
2499 Unlike the traditional unified diff format, which shows two files A and
2500 B with a single column that has - (minus — appears in A but removed in
2501 B), + (plus — missing in A but added to B), or " " (space — unchanged)
2502 prefix, this format compares two or more files file1, file2,... with
2503 one file X, and shows how X differs from each of fileN. One column for
2504 each of fileN is prepended to the output line to note how X’s line is
2505 different from it.
2506
2507 A - character in the column N means that the line appears in fileN but
2508 it does not appear in the result. A + character in the column N means
2509 that the line appears in the result, and fileN does not have that line
2510 (in other words, the line was added, from the point of view of that
2511 parent).
2512
2513 In the above example output, the function signature was changed from
2514 both files (hence two - removals from both file1 and file2, plus ++ to
2515 mean one line that was added does not appear in either file1 or file2).
2516 Also eight other lines are the same from file1 but do not appear in
2517 file2 (hence prefixed with +).
2518
2519 When shown by git diff-tree -c, it compares the parents of a merge
2520 commit with the merge result (i.e. file1..fileN are the parents). When
2521 shown by git diff-files -c, it compares the two unresolved merge
2522 parents with the working tree file (i.e. file1 is stage 2 aka "our
2523 version", file2 is stage 3 aka "their version").
2524
2526 git log --no-merges
2527 Show the whole commit history, but skip any merges
2528
2529 git log v2.6.12.. include/scsi drivers/scsi
2530 Show all commits since version v2.6.12 that changed any file in the
2531 include/scsi or drivers/scsi subdirectories
2532
2533 git log --since="2 weeks ago" -- gitk
2534 Show the changes during the last two weeks to the file gitk. The --
2535 is necessary to avoid confusion with the branch named gitk
2536
2537 git log --name-status release..test
2538 Show the commits that are in the "test" branch but not yet in the
2539 "release" branch, along with the list of paths each commit
2540 modifies.
2541
2542 git log --follow builtin/rev-list.c
2543 Shows the commits that changed builtin/rev-list.c, including those
2544 commits that occurred before the file was given its present name.
2545
2546 git log --branches --not --remotes=origin
2547 Shows all commits that are in any of local branches but not in any
2548 of remote-tracking branches for origin (what you have that origin
2549 doesn’t).
2550
2551 git log master --not --remotes=*/master
2552 Shows all commits that are in local master but not in any remote
2553 repository master branches.
2554
2555 git log -p -m --first-parent
2556 Shows the history including change diffs, but only from the “main
2557 branch” perspective, skipping commits that come from merged
2558 branches, and showing full diffs of changes introduced by the
2559 merges. This makes sense only when following a strict policy of
2560 merging all topic branches when staying on a single integration
2561 branch.
2562
2563 git log -L '/int main/',/^}/:main.c
2564 Shows how the function main() in the file main.c evolved over time.
2565
2566 git log -3
2567 Limits the number of commits to show to 3.
2568
2570 Git is to some extent character encoding agnostic.
2571
2572 • The contents of the blob objects are uninterpreted sequences of
2573 bytes. There is no encoding translation at the core level.
2574
2575 • Path names are encoded in UTF-8 normalization form C. This applies
2576 to tree objects, the index file, ref names, as well as path names
2577 in command line arguments, environment variables and config files
2578 (.git/config (see git-config(1)), gitignore(5), gitattributes(5)
2579 and gitmodules(5)).
2580
2581 Note that Git at the core level treats path names simply as
2582 sequences of non-NUL bytes, there are no path name encoding
2583 conversions (except on Mac and Windows). Therefore, using non-ASCII
2584 path names will mostly work even on platforms and file systems that
2585 use legacy extended ASCII encodings. However, repositories created
2586 on such systems will not work properly on UTF-8-based systems (e.g.
2587 Linux, Mac, Windows) and vice versa. Additionally, many Git-based
2588 tools simply assume path names to be UTF-8 and will fail to display
2589 other encodings correctly.
2590
2591 • Commit log messages are typically encoded in UTF-8, but other
2592 extended ASCII encodings are also supported. This includes
2593 ISO-8859-x, CP125x and many others, but not UTF-16/32, EBCDIC and
2594 CJK multi-byte encodings (GBK, Shift-JIS, Big5, EUC-x, CP9xx etc.).
2595
2596 Although we encourage that the commit log messages are encoded in
2597 UTF-8, both the core and Git Porcelain are designed not to force UTF-8
2598 on projects. If all participants of a particular project find it more
2599 convenient to use legacy encodings, Git does not forbid it. However,
2600 there are a few things to keep in mind.
2601
2602 1. git commit and git commit-tree issues a warning if the commit log
2603 message given to it does not look like a valid UTF-8 string, unless
2604 you explicitly say your project uses a legacy encoding. The way to
2605 say this is to have i18n.commitEncoding in .git/config file, like
2606 this:
2607
2608 [i18n]
2609 commitEncoding = ISO-8859-1
2610
2611 Commit objects created with the above setting record the value of
2612 i18n.commitEncoding in its encoding header. This is to help other
2613 people who look at them later. Lack of this header implies that the
2614 commit log message is encoded in UTF-8.
2615
2616 2. git log, git show, git blame and friends look at the encoding
2617 header of a commit object, and try to re-code the log message into
2618 UTF-8 unless otherwise specified. You can specify the desired
2619 output encoding with i18n.logOutputEncoding in .git/config file,
2620 like this:
2621
2622 [i18n]
2623 logOutputEncoding = ISO-8859-1
2624
2625 If you do not have this configuration variable, the value of
2626 i18n.commitEncoding is used instead.
2627
2628 Note that we deliberately chose not to re-code the commit log message
2629 when a commit is made to force UTF-8 at the commit object level,
2630 because re-coding to UTF-8 is not necessarily a reversible operation.
2631
2633 See git-config(1) for core variables and git-diff(1) for settings
2634 related to diff generation.
2635
2636 format.pretty
2637 Default for the --format option. (See Pretty Formats above.)
2638 Defaults to medium.
2639
2640 i18n.logOutputEncoding
2641 Encoding to use when displaying logs. (See Discussion above.)
2642 Defaults to the value of i18n.commitEncoding if set, and UTF-8
2643 otherwise.
2644
2645 Everything above this line in this section isn’t included from the git-
2646 config(1) documentation. The content that follows is the same as what’s
2647 found there:
2648
2649 log.abbrevCommit
2650 If true, makes git-log(1), git-show(1), and git-whatchanged(1)
2651 assume --abbrev-commit. You may override this option with
2652 --no-abbrev-commit.
2653
2654 log.date
2655 Set the default date-time mode for the log command. Setting a value
2656 for log.date is similar to using git log's --date option. See git-
2657 log(1) for details.
2658
2659 If the format is set to "auto:foo" and the pager is in use, format
2660 "foo" will be the used for the date format. Otherwise "default"
2661 will be used.
2662
2663 log.decorate
2664 Print out the ref names of any commits that are shown by the log
2665 command. If short is specified, the ref name prefixes refs/heads/,
2666 refs/tags/ and refs/remotes/ will not be printed. If full is
2667 specified, the full ref name (including prefix) will be printed. If
2668 auto is specified, then if the output is going to a terminal, the
2669 ref names are shown as if short were given, otherwise no ref names
2670 are shown. This is the same as the --decorate option of the git
2671 log.
2672
2673 log.initialDecorationSet
2674 By default, git log only shows decorations for certain known ref
2675 namespaces. If all is specified, then show all refs as decorations.
2676
2677 log.excludeDecoration
2678 Exclude the specified patterns from the log decorations. This is
2679 similar to the --decorate-refs-exclude command-line option, but the
2680 config option can be overridden by the --decorate-refs option.
2681
2682 log.diffMerges
2683 Set diff format to be used when --diff-merges=on is specified, see
2684 --diff-merges in git-log(1) for details. Defaults to separate.
2685
2686 log.follow
2687 If true, git log will act as if the --follow option was used when a
2688 single <path> is given. This has the same limitations as --follow,
2689 i.e. it cannot be used to follow multiple files and does not work
2690 well on non-linear history.
2691
2692 log.graphColors
2693 A list of colors, separated by commas, that can be used to draw
2694 history lines in git log --graph.
2695
2696 log.showRoot
2697 If true, the initial commit will be shown as a big creation event.
2698 This is equivalent to a diff against an empty tree. Tools like git-
2699 log(1) or git-whatchanged(1), which normally hide the root commit
2700 will now show it. True by default.
2701
2702 log.showSignature
2703 If true, makes git-log(1), git-show(1), and git-whatchanged(1)
2704 assume --show-signature.
2705
2706 log.mailmap
2707 If true, makes git-log(1), git-show(1), and git-whatchanged(1)
2708 assume --use-mailmap, otherwise assume --no-use-mailmap. True by
2709 default.
2710
2711 notes.mergeStrategy
2712 Which merge strategy to choose by default when resolving notes
2713 conflicts. Must be one of manual, ours, theirs, union, or
2714 cat_sort_uniq. Defaults to manual. See "NOTES MERGE STRATEGIES"
2715 section of git-notes(1) for more information on each strategy.
2716
2717 This setting can be overridden by passing the --strategy option to
2718 git-notes(1).
2719
2720 notes.<name>.mergeStrategy
2721 Which merge strategy to choose when doing a notes merge into
2722 refs/notes/<name>. This overrides the more general
2723 "notes.mergeStrategy". See the "NOTES MERGE STRATEGIES" section in
2724 git-notes(1) for more information on the available strategies.
2725
2726 notes.displayRef
2727 Which ref (or refs, if a glob or specified more than once), in
2728 addition to the default set by core.notesRef or GIT_NOTES_REF, to
2729 read notes from when showing commit messages with the git log
2730 family of commands.
2731
2732 This setting can be overridden with the GIT_NOTES_DISPLAY_REF
2733 environment variable, which must be a colon separated list of refs
2734 or globs.
2735
2736 A warning will be issued for refs that do not exist, but a glob
2737 that does not match any refs is silently ignored.
2738
2739 This setting can be disabled by the --no-notes option to the git
2740 log family of commands, or by the --notes=<ref> option accepted by
2741 those commands.
2742
2743 The effective value of "core.notesRef" (possibly overridden by
2744 GIT_NOTES_REF) is also implicitly added to the list of refs to be
2745 displayed.
2746
2747 notes.rewrite.<command>
2748 When rewriting commits with <command> (currently amend or rebase),
2749 if this variable is false, git will not copy notes from the
2750 original to the rewritten commit. Defaults to true. See also
2751 "notes.rewriteRef" below.
2752
2753 This setting can be overridden with the GIT_NOTES_REWRITE_REF
2754 environment variable, which must be a colon separated list of refs
2755 or globs.
2756
2757 notes.rewriteMode
2758 When copying notes during a rewrite (see the
2759 "notes.rewrite.<command>" option), determines what to do if the
2760 target commit already has a note. Must be one of overwrite,
2761 concatenate, cat_sort_uniq, or ignore. Defaults to concatenate.
2762
2763 This setting can be overridden with the GIT_NOTES_REWRITE_MODE
2764 environment variable.
2765
2766 notes.rewriteRef
2767 When copying notes during a rewrite, specifies the (fully
2768 qualified) ref whose notes should be copied. May be a glob, in
2769 which case notes in all matching refs will be copied. You may also
2770 specify this configuration several times.
2771
2772 Does not have a default value; you must configure this variable to
2773 enable note rewriting. Set it to refs/notes/commits to enable
2774 rewriting for the default commit notes.
2775
2776 Can be overridden with the GIT_NOTES_REWRITE_REF environment
2777 variable. See notes.rewrite.<command> above for a further
2778 description of its format.
