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.
100 Process binary files as if they were text.
103 Honor textconv filter settings.
106 Do not honor textconv filter settings.
111 Ignore case differences between the patterns and the
115 Don't match the pattern in binary files.
117 --max-depth <depth>::
118 For each <pathspec> given on command line, descend at most <depth>
119 levels of directories. A negative value means no limit.
120 This option is ignored if <pathspec> contains active wildcards.
121 In other words if "a*" matches a directory named "a*",
122 "*" is matched literally so --max-depth is still effective.
126 Match the pattern only at word boundary (either begin at the
127 beginning of a line, or preceded by a non-word character; end at
128 the end of a line or followed by a non-word character).
132 Select non-matching lines.
136 By default, the command shows the filename for each
137 match. `-h` option is used to suppress this output.
138 `-H` is there for completeness and does not do anything
139 except it overrides `-h` given earlier on the command
143 When run from a subdirectory, the command usually
144 outputs paths relative to the current directory. This
145 option forces paths to be output relative to the project
152 Use POSIX extended/basic regexp for patterns. Default
153 is to use basic regexp.
157 Use Perl-compatible regular expressions for patterns.
159 Support for these types of regular expressions is an optional
160 compile-time dependency. If Git wasn't compiled with support for them
161 providing this option will cause it to die.
165 Use fixed strings for patterns (don't interpret pattern
170 Prefix the line number to matching lines.
173 Prefix the 1-indexed byte-offset of the first match from the start of the
177 --files-with-matches::
180 --files-without-match::
181 Instead of showing every matched line, show only the
182 names of files that contain (or do not contain) matches.
183 For better compatibility with 'git diff', `--name-only` is a
184 synonym for `--files-with-matches`.
187 --open-files-in-pager[=<pager>]::
188 Open the matching files in the pager (not the output of 'grep').
189 If the pager happens to be "less" or "vi", and the user
190 specified only one pattern, the first file is positioned at
191 the first match automatically. The `pager` argument is
192 optional; if specified, it must be stuck to the option
193 without a space. If `pager` is unspecified, the default pager
194 will be used (see `core.pager` in linkgit:git-config[1]).
198 Output \0 instead of the character that normally follows a
203 Instead of showing every matched line, show the number of
207 Show colored matches.
208 The value must be always (the default), never, or auto.
211 Turn off match highlighting, even when the configuration file
212 gives the default to color output.
213 Same as `--color=never`.
216 Print an empty line between matches from different files.
219 Show the filename above the matches in that file instead of
220 at the start of each shown line.
224 Show the preceding line that contains the function name of
225 the match, unless the matching line is a function name itself.
226 The name is determined in the same way as 'git diff' works out
227 patch hunk headers (see 'Defining a custom hunk-header' in
228 linkgit:gitattributes[5]).
233 Show <num> leading and trailing lines, and place a line
234 containing `--` between contiguous groups of matches.
237 --after-context <num>::
238 Show <num> trailing lines, and place a line containing
239 `--` between contiguous groups of matches.
242 --before-context <num>::
243 Show <num> leading lines, and place a line containing
244 `--` between contiguous groups of matches.
248 Show the surrounding text from the previous line containing a
249 function name up to the one before the next function name,
250 effectively showing the whole function in which the match was
254 Number of grep worker threads to use.
255 See `grep.threads` in 'CONFIGURATION' for more information.
258 Read patterns from <file>, one per line.
261 The next parameter is the pattern. This option has to be
262 used for patterns starting with `-` and should be used in
263 scripts passing user input to grep. Multiple patterns are
270 Specify how multiple patterns are combined using Boolean
271 expressions. `--or` is the default operator. `--and` has
272 higher precedence than `--or`. `-e` has to be used for all
276 When giving multiple pattern expressions combined with `--or`,
277 this flag is specified to limit the match to files that
278 have lines to match all of them.
282 Do not output matched lines; instead, exit with status 0 when
283 there is a match and with non-zero status when there isn't.
286 Instead of searching tracked files in the working tree, search
287 blobs in the given trees.
290 Signals the end of options; the rest of the parameters
291 are <pathspec> limiters.
294 If given, limit the search to paths matching at least one pattern.
295 Both leading paths match and glob(7) patterns are supported.
297 For more details about the <pathspec> syntax, see the 'pathspec' entry
298 in linkgit:gitglossary[7].
303 `git grep 'time_t' -- '*.[ch]'`::
304 Looks for `time_t` in all tracked .c and .h files in the working
305 directory and its subdirectories.
307 `git grep -e '#define' --and \( -e MAX_PATH -e PATH_MAX \)`::
308 Looks for a line that has `#define` and either `MAX_PATH` or
311 `git grep --all-match -e NODE -e Unexpected`::
312 Looks for a line that has `NODE` or `Unexpected` in
313 files that have lines that match both.
315 `git grep solution -- :^Documentation`::
316 Looks for `solution`, excluding files in `Documentation`.
