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),
63 8 threads are used by default (for now).
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 has been initialized 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.
103 Process binary files as if they were text.
106 Honor textconv filter settings.
109 Do not honor textconv filter settings.
114 Ignore case differences between the patterns and the
118 Don't match the pattern in binary files.
120 --max-depth <depth>::
121 For each <pathspec> given on command line, descend at most <depth>
122 levels of directories. A value of -1 means no limit.
123 This option is ignored if <pathspec> contains active wildcards.
124 In other words if "a*" matches a directory named "a*",
125 "*" is matched literally so --max-depth is still effective.
129 Same as `--max-depth=-1`; this is the default.
132 Same as `--max-depth=0`.
136 Match the pattern only at word boundary (either begin at the
137 beginning of a line, or preceded by a non-word character; end at
138 the end of a line or followed by a non-word character).
142 Select non-matching lines.
146 By default, the command shows the filename for each
147 match. `-h` option is used to suppress this output.
148 `-H` is there for completeness and does not do anything
149 except it overrides `-h` given earlier on the command
153 When run from a subdirectory, the command usually
154 outputs paths relative to the current directory. This
155 option forces paths to be output relative to the project
162 Use POSIX extended/basic regexp for patterns. Default
163 is to use basic regexp.
167 Use Perl-compatible regular expressions for patterns.
169 Support for these types of regular expressions is an optional
170 compile-time dependency. If Git wasn't compiled with support for them
171 providing this option will cause it to die.
175 Use fixed strings for patterns (don't interpret pattern
180 Prefix the line number to matching lines.
183 Prefix the 1-indexed byte-offset of the first match from the start of the
187 --files-with-matches::
190 --files-without-match::
191 Instead of showing every matched line, show only the
192 names of files that contain (or do not contain) matches.
193 For better compatibility with 'git diff', `--name-only` is a
194 synonym for `--files-with-matches`.
197 --open-files-in-pager[=<pager>]::
198 Open the matching files in the pager (not the output of 'grep').
199 If the pager happens to be "less" or "vi", and the user
200 specified only one pattern, the first file is positioned at
201 the first match automatically. The `pager` argument is
202 optional; if specified, it must be stuck to the option
203 without a space. If `pager` is unspecified, the default pager
204 will be used (see `core.pager` in linkgit:git-config[1]).
208 Output \0 instead of the character that normally follows a
213 Print only the matched (non-empty) parts of a matching line, with each such
214 part on a separate output line.
218 Instead of showing every matched line, show the number of
222 Show colored matches.
223 The value must be always (the default), never, or auto.
226 Turn off match highlighting, even when the configuration file
227 gives the default to color output.
228 Same as `--color=never`.
231 Print an empty line between matches from different files.
234 Show the filename above the matches in that file instead of
235 at the start of each shown line.
239 Show the preceding line that contains the function name of
240 the match, unless the matching line is a function name itself.
241 The name is determined in the same way as 'git diff' works out
242 patch hunk headers (see 'Defining a custom hunk-header' in
243 linkgit:gitattributes[5]).
248 Show <num> leading and trailing lines, and place a line
249 containing `--` between contiguous groups of matches.
252 --after-context <num>::
253 Show <num> trailing lines, and place a line containing
254 `--` between contiguous groups of matches.
257 --before-context <num>::
258 Show <num> leading lines, and place a line containing
259 `--` between contiguous groups of matches.
263 Show the surrounding text from the previous line containing a
264 function name up to the one before the next function name,
265 effectively showing the whole function in which the match was
269 Number of grep worker threads to use.
270 See `grep.threads` in 'CONFIGURATION' for more information.
273 Read patterns from <file>, one per line.
275 Passing the pattern via <file> allows for providing a search pattern
278 Not all pattern types support patterns containing \0. Git will error
279 out if a given pattern type can't support such a pattern. The
280 `--perl-regexp` pattern type when compiled against the PCRE v2 backend
281 has the widest support for these types of patterns.
283 In versions of Git before 2.23.0 patterns containing \0 would be
284 silently considered fixed. This was never documented, there were also
285 odd and undocumented interactions between e.g. non-ASCII patterns
286 containing \0 and `--ignore-case`.
288 In future versions we may learn to support patterns containing \0 for
289 more search backends, until then we'll die when the pattern type in
290 question doesn't support them.
293 The next parameter is the pattern. This option has to be
294 used for patterns starting with `-` and should be used in
295 scripts passing user input to grep. Multiple patterns are
302 Specify how multiple patterns are combined using Boolean
303 expressions. `--or` is the default operator. `--and` has
304 higher precedence than `--or`. `-e` has to be used for all
308 When giving multiple pattern expressions combined with `--or`,
309 this flag is specified to limit the match to files that
310 have lines to match all of them.
314 Do not output matched lines; instead, exit with status 0 when
315 there is a match and with non-zero status when there isn't.
318 Instead of searching tracked files in the working tree, search
319 blobs in the given trees.
322 Signals the end of options; the rest of the parameters
323 are <pathspec> limiters.
326 If given, limit the search to paths matching at least one pattern.
327 Both leading paths match and glob(7) patterns are supported.
329 For more details about the <pathspec> syntax, see the 'pathspec' entry
330 in linkgit:gitglossary[7].
335 `git grep 'time_t' -- '*.[ch]'`::
336 Looks for `time_t` in all tracked .c and .h files in the working
337 directory and its subdirectories.
339 `git grep -e '#define' --and \( -e MAX_PATH -e PATH_MAX \)`::
340 Looks for a line that has `#define` and either `MAX_PATH` or
343 `git grep --all-match -e NODE -e Unexpected`::
344 Looks for a line that has `NODE` or `Unexpected` in
345 files that have lines that match both.
347 `git grep solution -- :^Documentation`::
348 Looks for `solution`, excluding files in `Documentation`.
