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.
44 Instead of searching tracked files in the working tree, search
45 blobs registered in the index file.
48 Search files in the current directory that is not managed by Git.
51 In addition to searching in the tracked files in the working
52 tree, search also in untracked files.
54 --no-exclude-standard::
55 Also search in ignored files by not honoring the `.gitignore`
56 mechanism. Only useful with `--untracked`.
59 Do not pay attention to ignored files specified via the `.gitignore`
60 mechanism. Only useful when searching files in the current directory
63 --recurse-submodules::
64 Recursively search in each submodule that is active and
65 checked out in the repository. When used in combination with the
66 <tree> option the prefix of all submodule output will be the name of
67 the parent project's <tree> object. This option has no effect
68 if `--no-index` is given.
72 Process binary files as if they were text.
75 Honor textconv filter settings.
78 Do not honor textconv filter settings.
83 Ignore case differences between the patterns and the
87 Don't match the pattern in binary files.
90 For each <pathspec> given on command line, descend at most <depth>
91 levels of directories. A value of -1 means no limit.
92 This option is ignored if <pathspec> contains active wildcards.
93 In other words if "a*" matches a directory named "a*",
94 "*" is matched literally so --max-depth is still effective.
98 Same as `--max-depth=-1`; this is the default.
101 Same as `--max-depth=0`.
105 Match the pattern only at word boundary (either begin at the
106 beginning of a line, or preceded by a non-word character; end at
107 the end of a line or followed by a non-word character).
111 Select non-matching lines.
115 By default, the command shows the filename for each
116 match. `-h` option is used to suppress this output.
117 `-H` is there for completeness and does not do anything
118 except it overrides `-h` given earlier on the command
122 When run from a subdirectory, the command usually
123 outputs paths relative to the current directory. This
124 option forces paths to be output relative to the project
131 Use POSIX extended/basic regexp for patterns. Default
132 is to use basic regexp.
136 Use Perl-compatible regular expressions for patterns.
138 Support for these types of regular expressions is an optional
139 compile-time dependency. If Git wasn't compiled with support for them
140 providing this option will cause it to die.
144 Use fixed strings for patterns (don't interpret pattern
149 Prefix the line number to matching lines.
152 Prefix the 1-indexed byte-offset of the first match from the start of the
156 --files-with-matches::
159 --files-without-match::
160 Instead of showing every matched line, show only the
161 names of files that contain (or do not contain) matches.
162 For better compatibility with 'git diff', `--name-only` is a
163 synonym for `--files-with-matches`.
166 --open-files-in-pager[=<pager>]::
167 Open the matching files in the pager (not the output of 'grep').
168 If the pager happens to be "less" or "vi", and the user
169 specified only one pattern, the first file is positioned at
170 the first match automatically. The `pager` argument is
171 optional; if specified, it must be stuck to the option
172 without a space. If `pager` is unspecified, the default pager
173 will be used (see `core.pager` in linkgit:git-config[1]).
177 Use \0 as the delimiter for pathnames in the output, and print
178 them verbatim. Without this option, pathnames with "unusual"
179 characters are quoted as explained for the configuration
180 variable core.quotePath (see linkgit:git-config[1]).
184 Print only the matched (non-empty) parts of a matching line, with each such
185 part on a separate output line.
189 Instead of showing every matched line, show the number of
193 Show colored matches.
194 The value must be always (the default), never, or auto.
197 Turn off match highlighting, even when the configuration file
198 gives the default to color output.
199 Same as `--color=never`.
202 Print an empty line between matches from different files.
205 Show the filename above the matches in that file instead of
206 at the start of each shown line.
210 Show the preceding line that contains the function name of
211 the match, unless the matching line is a function name itself.
212 The name is determined in the same way as `git diff` works out
213 patch hunk headers (see 'Defining a custom hunk-header' in
214 linkgit:gitattributes[5]).
219 Show <num> leading and trailing lines, and place a line
220 containing `--` between contiguous groups of matches.
223 --after-context <num>::
224 Show <num> trailing lines, and place a line containing
225 `--` between contiguous groups of matches.
228 --before-context <num>::
229 Show <num> leading lines, and place a line containing
230 `--` between contiguous groups of matches.
234 Show the surrounding text from the previous line containing a
235 function name up to the one before the next function name,
236 effectively showing the whole function in which the match was
237 found. The function names are determined in the same way as
238 `git diff` works out patch hunk headers (see 'Defining a
239 custom hunk-header' in linkgit:gitattributes[5]).
242 Number of grep worker threads to use.
243 See `grep.threads` in 'CONFIGURATION' for more information.
246 Read patterns from <file>, one per line.
248 Passing the pattern via <file> allows for providing a search pattern
251 Not all pattern types support patterns containing \0. Git will error
252 out if a given pattern type can't support such a pattern. The
253 `--perl-regexp` pattern type when compiled against the PCRE v2 backend
254 has the widest support for these types of patterns.
256 In versions of Git before 2.23.0 patterns containing \0 would be
257 silently considered fixed. This was never documented, there were also
258 odd and undocumented interactions between e.g. non-ASCII patterns
259 containing \0 and `--ignore-case`.
261 In future versions we may learn to support patterns containing \0 for
262 more search backends, until then we'll die when the pattern type in
263 question doesn't support them.
266 The next parameter is the pattern. This option has to be
267 used for patterns starting with `-` and should be used in
268 scripts passing user input to grep. Multiple patterns are
275 Specify how multiple patterns are combined using Boolean
276 expressions. `--or` is the default operator. `--and` has
277 higher precedence than `--or`. `-e` has to be used for all
281 When giving multiple pattern expressions combined with `--or`,
282 this flag is specified to limit the match to files that
283 have lines to match all of them.
287 Do not output matched lines; instead, exit with status 0 when
288 there is a match and with non-zero status when there isn't.
291 Instead of searching tracked files in the working tree, search
292 blobs in the given trees.
295 Signals the end of options; the rest of the parameters
296 are <pathspec> limiters.
299 If given, limit the search to paths matching at least one pattern.
300 Both leading paths match and glob(7) patterns are supported.
302 For more details about the <pathspec> syntax, see the 'pathspec' entry
303 in linkgit:gitglossary[7].
308 `git grep 'time_t' -- '*.[ch]'`::
309 Looks for `time_t` in all tracked .c and .h files in the working
310 directory and its subdirectories.
312 `git grep -e '#define' --and \( -e MAX_PATH -e PATH_MAX \)`::
313 Looks for a line that has `#define` and either `MAX_PATH` or
316 `git grep --all-match -e NODE -e Unexpected`::
317 Looks for a line that has `NODE` or `Unexpected` in
318 files that have lines that match both.
320 `git grep solution -- :^Documentation`::
321 Looks for `solution`, excluding files in `Documentation`.
326 The `--threads` option (and the grep.threads configuration) will be ignored when
327 `--open-files-in-pager` is used, forcing a single-threaded execution.
329 When grepping the object store (with `--cached` or giving tree objects), running
330 with multiple threads might perform slower than single threaded if `--textconv`
331 is given and there're too many text conversions. So if you experience low
332 performance in this case, it might be desirable to use `--threads=1`.
338 If set to true, enable `-n` option by default.
341 If set to true, enable the `--column` option by default.
344 Set the default matching behavior. Using a value of 'basic', 'extended',
345 'fixed', or 'perl' will enable the `--basic-regexp`, `--extended-regexp`,
346 `--fixed-strings`, or `--perl-regexp` option accordingly, while the
347 value 'default' will return to the default matching behavior.
349 grep.extendedRegexp::
350 If set to true, enable `--extended-regexp` option by default. This
351 option is ignored when the `grep.patternType` option is set to a value
352 other than 'default'.
355 Number of grep worker threads to use. If unset (or set to 0), Git will
356 use as many threads as the number of logical cores available.
359 If set to true, enable `--full-name` option by default.
361 grep.fallbackToNoIndex::
362 If set to true, fall back to git grep --no-index if git grep
363 is executed outside of a git repository. Defaults to false.
