35 Look for specified patterns in the tracked files in the work tree, blobs
36 registered in the index file, or blobs in given tree objects. Patterns
37 are lists of one or more search expressions separated by newline
38 characters. An empty string as search expression matches all lines.
45 If set to true, enable `-n` option by default.
48 If set to true, enable the `--column` option by default.
51 Set the default matching behavior. Using a value of 'basic', 'extended',
52 'fixed', or 'perl' will enable the `--basic-regexp`, `--extended-regexp`,
53 `--fixed-strings`, or `--perl-regexp` option accordingly, while the
54 value 'default' will return to the default matching behavior.
57 If set to true, enable `--extended-regexp` option by default. This
58 option is ignored when the `grep.patternType` option is set to a value
62 Number of grep worker threads to use. If unset (or set to 0), Git will
63 use as many threads as the number of logical cores available.
66 If set to true, enable `--full-name` option by default.
68 grep.fallbackToNoIndex::
69 If set to true, fall back to git grep --no-index if git grep
70 is executed outside of a git repository. Defaults to false.
76 Instead of searching tracked files in the working tree, search
77 blobs registered in the index file.
80 Search files in the current directory that is not managed by Git.
83 In addition to searching in the tracked files in the working
84 tree, search also in untracked files.
86 --no-exclude-standard::
87 Also search in ignored files by not honoring the `.gitignore`
88 mechanism. Only useful with `--untracked`.
91 Do not pay attention to ignored files specified via the `.gitignore`
92 mechanism. Only useful when searching files in the current directory
95 --recurse-submodules::
96 Recursively search in each submodule that is active and
97 checked out in the repository. When used in combination with the
98 <tree> option the prefix of all submodule output will be the name of
99 the parent project's <tree> object. This option has no effect
100 if `--no-index` is given.
104 Process binary files as if they were text.
107 Honor textconv filter settings.
110 Do not honor textconv filter settings.
115 Ignore case differences between the patterns and the
119 Don't match the pattern in binary files.
121 --max-depth <depth>::
122 For each <pathspec> given on command line, descend at most <depth>
123 levels of directories. A value of -1 means no limit.
124 This option is ignored if <pathspec> contains active wildcards.
125 In other words if "a*" matches a directory named "a*",
126 "*" is matched literally so --max-depth is still effective.
130 Same as `--max-depth=-1`; this is the default.
133 Same as `--max-depth=0`.
137 Match the pattern only at word boundary (either begin at the
138 beginning of a line, or preceded by a non-word character; end at
139 the end of a line or followed by a non-word character).
143 Select non-matching lines.
147 By default, the command shows the filename for each
148 match. `-h` option is used to suppress this output.
149 `-H` is there for completeness and does not do anything
150 except it overrides `-h` given earlier on the command
154 When run from a subdirectory, the command usually
155 outputs paths relative to the current directory. This
156 option forces paths to be output relative to the project
163 Use POSIX extended/basic regexp for patterns. Default
164 is to use basic regexp.
168 Use Perl-compatible regular expressions for patterns.
170 Support for these types of regular expressions is an optional
171 compile-time dependency. If Git wasn't compiled with support for them
172 providing this option will cause it to die.
176 Use fixed strings for patterns (don't interpret pattern
181 Prefix the line number to matching lines.
184 Prefix the 1-indexed byte-offset of the first match from the start of the
188 --files-with-matches::
191 --files-without-match::
192 Instead of showing every matched line, show only the
193 names of files that contain (or do not contain) matches.
194 For better compatibility with 'git diff', `--name-only` is a
195 synonym for `--files-with-matches`.
198 --open-files-in-pager[=<pager>]::
199 Open the matching files in the pager (not the output of 'grep').
200 If the pager happens to be "less" or "vi", and the user
201 specified only one pattern, the first file is positioned at
202 the first match automatically. The `pager` argument is
203 optional; if specified, it must be stuck to the option
204 without a space. If `pager` is unspecified, the default pager
205 will be used (see `core.pager` in linkgit:git-config[1]).
209 Output \0 instead of the character that normally follows a
214 Print only the matched (non-empty) parts of a matching line, with each such
215 part on a separate output line.
219 Instead of showing every matched line, show the number of
223 Show colored matches.
224 The value must be always (the default), never, or auto.
227 Turn off match highlighting, even when the configuration file
228 gives the default to color output.
229 Same as `--color=never`.
232 Print an empty line between matches from different files.
235 Show the filename above the matches in that file instead of
236 at the start of each shown line.
240 Show the preceding line that contains the function name of
241 the match, unless the matching line is a function name itself.
242 The name is determined in the same way as 'git diff' works out
243 patch hunk headers (see 'Defining a custom hunk-header' in
244 linkgit:gitattributes[5]).
249 Show <num> leading and trailing lines, and place a line
250 containing `--` between contiguous groups of matches.
253 --after-context <num>::
254 Show <num> trailing lines, and place a line containing
255 `--` between contiguous groups of matches.
258 --before-context <num>::
259 Show <num> leading lines, and place a line containing
260 `--` between contiguous groups of matches.
264 Show the surrounding text from the previous line containing a
265 function name up to the one before the next function name,
266 effectively showing the whole function in which the match was
270 Number of grep worker threads to use.
271 See `grep.threads` in 'CONFIGURATION' for more information.
274 Read patterns from <file>, one per line.
276 Passing the pattern via <file> allows for providing a search pattern
279 Not all pattern types support patterns containing \0. Git will error
280 out if a given pattern type can't support such a pattern. The
281 `--perl-regexp` pattern type when compiled against the PCRE v2 backend
282 has the widest support for these types of patterns.
284 In versions of Git before 2.23.0 patterns containing \0 would be
285 silently considered fixed. This was never documented, there were also
286 odd and undocumented interactions between e.g. non-ASCII patterns
287 containing \0 and `--ignore-case`.
289 In future versions we may learn to support patterns containing \0 for
290 more search backends, until then we'll die when the pattern type in
291 question doesn't support them.
294 The next parameter is the pattern. This option has to be
295 used for patterns starting with `-` and should be used in
296 scripts passing user input to grep. Multiple patterns are
303 Specify how multiple patterns are combined using Boolean
304 expressions. `--or` is the default operator. `--and` has
305 higher precedence than `--or`. `-e` has to be used for all
309 When giving multiple pattern expressions combined with `--or`,
310 this flag is specified to limit the match to files that
311 have lines to match all of them.
315 Do not output matched lines; instead, exit with status 0 when
316 there is a match and with non-zero status when there isn't.
319 Instead of searching tracked files in the working tree, search
320 blobs in the given trees.
323 Signals the end of options; the rest of the parameters
324 are <pathspec> limiters.
327 If given, limit the search to paths matching at least one pattern.
328 Both leading paths match and glob(7) patterns are supported.
330 For more details about the <pathspec> syntax, see the 'pathspec' entry
331 in linkgit:gitglossary[7].
336 `git grep 'time_t' -- '*.[ch]'`::
337 Looks for `time_t` in all tracked .c and .h files in the working
338 directory and its subdirectories.
340 `git grep -e '#define' --and \( -e MAX_PATH -e PATH_MAX \)`::
341 Looks for a line that has `#define` and either `MAX_PATH` or
344 `git grep --all-match -e NODE -e Unexpected`::
345 Looks for a line that has `NODE` or `Unexpected` in
346 files that have lines that match both.
348 `git grep solution -- :^Documentation`::
349 Looks for `solution`, excluding files in `Documentation`.
354 The `--threads` option (and the grep.threads configuration) will be ignored when
355 `--open-files-in-pager` is used, forcing a single-threaded execution.
357 When grepping the object store (with `--cached` or giving tree objects), running
358 with multiple threads might perform slower than single threaded if `--textconv`
359 is given and there're too many text conversions. So if you experience low
360 performance in this case, it might be desirable to use `--threads=1`.
