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 Set the default matching behavior. Using a value of 'basic', 'extended',
49 'fixed', or 'perl' will enable the `--basic-regexp`, `--extended-regexp`,
50 `--fixed-strings`, or `--perl-regexp` option accordingly, while the
51 value 'default' will return to the default matching behavior.
54 If set to true, enable `--extended-regexp` option by default. This
55 option is ignored when the `grep.patternType` option is set to a value
59 Number of grep worker threads to use. If unset (or set to 0),
60 8 threads are used by default (for now).
63 If set to true, enable `--full-name` option by default.
65 grep.fallbackToNoIndex::
66 If set to true, fall back to git grep --no-index if git grep
67 is executed outside of a git repository. Defaults to false.
73 Instead of searching tracked files in the working tree, search
74 blobs registered in the index file.
77 Search files in the current directory that is not managed by Git.
80 In addition to searching in the tracked files in the working
81 tree, search also in untracked files.
83 --no-exclude-standard::
84 Also search in ignored files by not honoring the `.gitignore`
85 mechanism. Only useful with `--untracked`.
88 Do not pay attention to ignored files specified via the `.gitignore`
89 mechanism. Only useful when searching files in the current directory
92 --recurse-submodules::
93 Recursively search in each submodule that has been initialized and
94 checked out in the repository. When used in combination with the
95 <tree> option the prefix of all submodule output will be the name of
96 the parent project's <tree> object.
98 --parent-basename <basename>::
99 For internal use only. In order to produce uniform output with the
100 --recurse-submodules option, this option can be used to provide the
101 basename of a parent's <tree> object to a submodule so the submodule
102 can prefix its output with the parent's name rather than the SHA1 of
107 Process binary files as if they were text.
110 Honor textconv filter settings.
113 Do not honor textconv filter settings.
118 Ignore case differences between the patterns and the
122 Don't match the pattern in binary files.
124 --max-depth <depth>::
125 For each <pathspec> given on command line, descend at most <depth>
126 levels of directories. A negative value means no limit.
127 This option is ignored if <pathspec> contains active wildcards.
128 In other words if "a*" matches a directory named "a*",
129 "*" is matched literally so --max-depth is still effective.
133 Match the pattern only at word boundary (either begin at the
134 beginning of a line, or preceded by a non-word character; end at
135 the end of a line or followed by a non-word character).
139 Select non-matching lines.
143 By default, the command shows the filename for each
144 match. `-h` option is used to suppress this output.
145 `-H` is there for completeness and does not do anything
146 except it overrides `-h` given earlier on the command
150 When run from a subdirectory, the command usually
151 outputs paths relative to the current directory. This
152 option forces paths to be output relative to the project
159 Use POSIX extended/basic regexp for patterns. Default
160 is to use basic regexp.
164 Use Perl-compatible regular expressions for patterns.
166 Support for these types of regular expressions is an optional
167 compile-time dependency. If Git wasn't compiled with support for them
168 providing this option will cause it to die.
172 Use fixed strings for patterns (don't interpret pattern
177 Prefix the line number to matching lines.
180 --files-with-matches::
183 --files-without-match::
184 Instead of showing every matched line, show only the
185 names of files that contain (or do not contain) matches.
186 For better compatibility with 'git diff', `--name-only` is a
187 synonym for `--files-with-matches`.
190 --open-files-in-pager[=<pager>]::
191 Open the matching files in the pager (not the output of 'grep').
192 If the pager happens to be "less" or "vi", and the user
193 specified only one pattern, the first file is positioned at
194 the first match automatically. The `pager` argument is
195 optional; if specified, it must be stuck to the option
196 without a space. If `pager` is unspecified, the default pager
197 will be used (see `core.pager` in linkgit:git-config[1]).
201 Output \0 instead of the character that normally follows a
206 Instead of showing every matched line, show the number of
210 Show colored matches.
211 The value must be always (the default), never, or auto.
214 Turn off match highlighting, even when the configuration file
215 gives the default to color output.
216 Same as `--color=never`.
219 Print an empty line between matches from different files.
222 Show the filename above the matches in that file instead of
223 at the start of each shown line.
227 Show the preceding line that contains the function name of
228 the match, unless the matching line is a function name itself.
229 The name is determined in the same way as 'git diff' works out
230 patch hunk headers (see 'Defining a custom hunk-header' in
231 linkgit:gitattributes[5]).
236 Show <num> leading and trailing lines, and place a line
237 containing `--` between contiguous groups of matches.
240 --after-context <num>::
241 Show <num> trailing lines, and place a line containing
242 `--` between contiguous groups of matches.
245 --before-context <num>::
246 Show <num> leading lines, and place a line containing
247 `--` between contiguous groups of matches.
251 Show the surrounding text from the previous line containing a
252 function name up to the one before the next function name,
253 effectively showing the whole function in which the match was
257 Number of grep worker threads to use.
258 See `grep.threads` in 'CONFIGURATION' for more information.
261 Read patterns from <file>, one per line.
264 The next parameter is the pattern. This option has to be
265 used for patterns starting with `-` and should be used in
266 scripts passing user input to grep. Multiple patterns are
273 Specify how multiple patterns are combined using Boolean
274 expressions. `--or` is the default operator. `--and` has
275 higher precedence than `--or`. `-e` has to be used for all
279 When giving multiple pattern expressions combined with `--or`,
280 this flag is specified to limit the match to files that
281 have lines to match all of them.
285 Do not output matched lines; instead, exit with status 0 when
286 there is a match and with non-zero status when there isn't.
289 Instead of searching tracked files in the working tree, search
290 blobs in the given trees.
293 Signals the end of options; the rest of the parameters
294 are <pathspec> limiters.
297 If given, limit the search to paths matching at least one pattern.
298 Both leading paths match and glob(7) patterns are supported.
300 For more details about the <pathspec> syntax, see the 'pathspec' entry
301 in linkgit:gitglossary[7].
306 `git grep 'time_t' -- '*.[ch]'`::
307 Looks for `time_t` in all tracked .c and .h files in the working
308 directory and its subdirectories.
310 `git grep -e '#define' --and \( -e MAX_PATH -e PATH_MAX \)`::
311 Looks for a line that has `#define` and either `MAX_PATH` or
314 `git grep --all-match -e NODE -e Unexpected`::
315 Looks for a line that has `NODE` or `Unexpected` in
316 files that have lines that match both.
318 `git grep solution -- :^Documentation`::
319 Looks for `solution`, excluding files in `Documentation`.
