DESCRIPTION

32       Look for specified patterns in the tracked files in the work tree,
33       blobs registered in the index file, or blobs in given tree objects.
34       Patterns are lists of one or more search expressions separated by
35       newline characters. An empty string as search expression matches all
36       lines.
37

CONFIGURATION

39       grep.lineNumber
40           If set to true, enable -n option by default.
41
42       grep.column
43           If set to true, enable the --column option by default.
44
45       grep.patternType
46           Set the default matching behavior. Using a value of basic,
47           extended, fixed, or perl will enable the --basic-regexp,
48           --extended-regexp, --fixed-strings, or --perl-regexp option
49           accordingly, while the value default will return to the default
50           matching behavior.
51
52       grep.extendedRegexp
53           If set to true, enable --extended-regexp option by default. This
54           option is ignored when the grep.patternType option is set to a
55           value other than default.
56
57       grep.threads
58           Number of grep worker threads to use. If unset (or set to 0), 8
59           threads are used by default (for now).
60
61       grep.fullName
62           If set to true, enable --full-name option by default.
63
64       grep.fallbackToNoIndex
65           If set to true, fall back to git grep --no-index if git grep is
66           executed outside of a git repository. Defaults to false.
67

OPTIONS

69       --cached
70           Instead of searching tracked files in the working tree, search
71           blobs registered in the index file.
72
73       --no-index
74           Search files in the current directory that is not managed by Git.
75
76       --untracked
77           In addition to searching in the tracked files in the working tree,
78           search also in untracked files.
79
80       --no-exclude-standard
81           Also search in ignored files by not honoring the .gitignore
82           mechanism. Only useful with --untracked.
83
84       --exclude-standard
85           Do not pay attention to ignored files specified via the .gitignore
86           mechanism. Only useful when searching files in the current
87           directory with --no-index.
88
89       --recurse-submodules
90           Recursively search in each submodule that has been initialized and
91           checked out in the repository. When used in combination with the
92           <tree> option the prefix of all submodule output will be the name
93           of the parent project’s <tree> object.
94
95       -a, --text
96           Process binary files as if they were text.
97
98       --textconv
99           Honor textconv filter settings.
100
101       --no-textconv
102           Do not honor textconv filter settings. This is the default.
103
104       -i, --ignore-case
105           Ignore case differences between the patterns and the files.
106
107       -I
108           Don’t match the pattern in binary files.
109
110       --max-depth <depth>
111           For each <pathspec> given on command line, descend at most <depth>
112           levels of directories. A value of -1 means no limit. This option is
113           ignored if <pathspec> contains active wildcards. In other words if
114           "a*" matches a directory named "a*", "*" is matched literally so
115           --max-depth is still effective.
116
117       -r, --recursive
118           Same as --max-depth=-1; this is the default.
119
120       --no-recursive
121           Same as --max-depth=0.
122
123       -w, --word-regexp
124           Match the pattern only at word boundary (either begin at the
125           beginning of a line, or preceded by a non-word character; end at
126           the end of a line or followed by a non-word character).
127
128       -v, --invert-match
129           Select non-matching lines.
130
131       -h, -H
132           By default, the command shows the filename for each match.  -h
133           option is used to suppress this output.  -H is there for
134           completeness and does not do anything except it overrides -h given
135           earlier on the command line.
136
137       --full-name
138           When run from a subdirectory, the command usually outputs paths
139           relative to the current directory. This option forces paths to be
140           output relative to the project top directory.
141
142       -E, --extended-regexp, -G, --basic-regexp
143           Use POSIX extended/basic regexp for patterns. Default is to use
144           basic regexp.
145
146       -P, --perl-regexp
147           Use Perl-compatible regular expressions for patterns.
148
149           Support for these types of regular expressions is an optional
150           compile-time dependency. If Git wasn’t compiled with support for
151           them providing this option will cause it to die.
152
153       -F, --fixed-strings
154           Use fixed strings for patterns (don’t interpret pattern as a
155           regex).
156
157       -n, --line-number
158           Prefix the line number to matching lines.
159
160       --column
161           Prefix the 1-indexed byte-offset of the first match from the start
162           of the matching line.
163
164       -l, --files-with-matches, --name-only, -L, --files-without-match
165           Instead of showing every matched line, show only the names of files
166           that contain (or do not contain) matches. For better compatibility
167           with git diff, --name-only is a synonym for --files-with-matches.
168
169       -O[<pager>], --open-files-in-pager[=<pager>]
170           Open the matching files in the pager (not the output of grep). If
171           the pager happens to be "less" or "vi", and the user specified only
172           one pattern, the first file is positioned at the first match
173           automatically. The pager argument is optional; if specified, it
174           must be stuck to the option without a space. If pager is
175           unspecified, the default pager will be used (see core.pager in git-
176           config(1)).
177
178       -z, --null
179           Output \0 instead of the character that normally follows a file
180           name.
181
182       -o, --only-matching
183           Print only the matched (non-empty) parts of a matching line, with
184           each such part on a separate output line.
185
186       -c, --count
187           Instead of showing every matched line, show the number of lines
188           that match.
189
190       --color[=<when>]
191           Show colored matches. The value must be always (the default),
192           never, or auto.
193
194       --no-color
195           Turn off match highlighting, even when the configuration file gives
196           the default to color output. Same as --color=never.
197
198       --break
199           Print an empty line between matches from different files.
200
201       --heading
202           Show the filename above the matches in that file instead of at the
203           start of each shown line.
204
205       -p, --show-function
206           Show the preceding line that contains the function name of the
207           match, unless the matching line is a function name itself. The name
208           is determined in the same way as git diff works out patch hunk
209           headers (see Defining a custom hunk-header in gitattributes(5)).
210
211       -<num>, -C <num>, --context <num>
212           Show <num> leading and trailing lines, and place a line containing
213           -- between contiguous groups of matches.
214
215       -A <num>, --after-context <num>
216           Show <num> trailing lines, and place a line containing -- between
217           contiguous groups of matches.
218
219       -B <num>, --before-context <num>
220           Show <num> leading lines, and place a line containing -- between
221           contiguous groups of matches.
222
223       -W, --function-context
224           Show the surrounding text from the previous line containing a
225           function name up to the one before the next function name,
226           effectively showing the whole function in which the match was
227           found.
228
229       --threads <num>
230           Number of grep worker threads to use. See grep.threads in
231           CONFIGURATION for more information.
232
233       -f <file>
234           Read patterns from <file>, one per line.
235
236       -e
237           The next parameter is the pattern. This option has to be used for
238           patterns starting with - and should be used in scripts passing user
239           input to grep. Multiple patterns are combined by or.
240
241       --and, --or, --not, ( ... )
242           Specify how multiple patterns are combined using Boolean
243           expressions.  --or is the default operator.  --and has higher
244           precedence than --or.  -e has to be used for all patterns.
245
246       --all-match
247           When giving multiple pattern expressions combined with --or, this
248           flag is specified to limit the match to files that have lines to
249           match all of them.
250
251       -q, --quiet
252           Do not output matched lines; instead, exit with status 0 when there
253           is a match and with non-zero status when there isn’t.
254
255       <tree>...
256           Instead of searching tracked files in the working tree, search
257           blobs in the given trees.
258
259       --
260           Signals the end of options; the rest of the parameters are
261           <pathspec> limiters.
262
263       <pathspec>...
264           If given, limit the search to paths matching at least one pattern.
265           Both leading paths match and glob(7) patterns are supported.
266
267           For more details about the <pathspec> syntax, see the pathspec
268           entry in gitglossary(7).

EXAMPLES

271       git grep 'time_t' -- '*.[ch]'
272           Looks for time_t in all tracked .c and .h files in the working
273           directory and its subdirectories.
274
275       git grep -e '#define' --and \( -e MAX_PATH -e PATH_MAX \)
276           Looks for a line that has #define and either MAX_PATH or PATH_MAX.
277
278       git grep --all-match -e NODE -e Unexpected
279           Looks for a line that has NODE or Unexpected in files that have
280           lines that match both.
281
282       git grep solution -- :^Documentation
283           Looks for solution, excluding files in Documentation.
