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.
98 Process binary files as if they were text.
101 Honor textconv filter settings.
104 Do not honor textconv filter settings.
109 Ignore case differences between the patterns and the
113 Don't match the pattern in binary files.
115 --max-depth <depth>::
116 For each <pathspec> given on command line, descend at most <depth>
117 levels of directories. A negative value means no limit.
118 This option is ignored if <pathspec> contains active wildcards.
119 In other words if "a*" matches a directory named "a*",
120 "*" is matched literally so --max-depth is still effective.
124 Match the pattern only at word boundary (either begin at the
125 beginning of a line, or preceded by a non-word character; end at
126 the end of a line or followed by a non-word character).
130 Select non-matching lines.
134 By default, the command shows the filename for each
135 match. `-h` option is used to suppress this output.
136 `-H` is there for completeness and does not do anything
137 except it overrides `-h` given earlier on the command
141 When run from a subdirectory, the command usually
142 outputs paths relative to the current directory. This
143 option forces paths to be output relative to the project
150 Use POSIX extended/basic regexp for patterns. Default
151 is to use basic regexp.
155 Use Perl-compatible regexp for patterns. Requires libpcre to be
160 Use fixed strings for patterns (don't interpret pattern
165 Prefix the line number to matching lines.
168 --files-with-matches::
171 --files-without-match::
172 Instead of showing every matched line, show only the
173 names of files that contain (or do not contain) matches.
174 For better compatibility with 'git diff', `--name-only` is a
175 synonym for `--files-with-matches`.
178 --open-files-in-pager[=<pager>]::
179 Open the matching files in the pager (not the output of 'grep').
180 If the pager happens to be "less" or "vi", and the user
181 specified only one pattern, the first file is positioned at
182 the first match automatically. The `pager` argument is
183 optional; if specified, it must be stuck to the option
184 without a space. If `pager` is unspecified, the default pager
185 will be used (see `core.pager` in linkgit:git-config[1]).
189 Output \0 instead of the character that normally follows a
194 Instead of showing every matched line, show the number of
198 Show colored matches.
199 The value must be always (the default), never, or auto.
202 Turn off match highlighting, even when the configuration file
203 gives the default to color output.
204 Same as `--color=never`.
207 Print an empty line between matches from different files.
210 Show the filename above the matches in that file instead of
211 at the start of each shown line.
215 Show the preceding line that contains the function name of
216 the match, unless the matching line is a function name itself.
217 The name is determined in the same way as 'git diff' works out
218 patch hunk headers (see 'Defining a custom hunk-header' in
219 linkgit:gitattributes[5]).
224 Show <num> leading and trailing lines, and place a line
225 containing `--` between contiguous groups of matches.
228 --after-context <num>::
229 Show <num> trailing lines, and place a line containing
230 `--` between contiguous groups of matches.
233 --before-context <num>::
234 Show <num> leading lines, and place a line containing
235 `--` between contiguous groups of matches.
239 Show the surrounding text from the previous line containing a
240 function name up to the one before the next function name,
241 effectively showing the whole function in which the match was
245 Number of grep worker threads to use.
246 See `grep.threads` in 'CONFIGURATION' for more information.
249 Read patterns from <file>, one per line.
252 The next parameter is the pattern. This option has to be
253 used for patterns starting with `-` and should be used in
254 scripts passing user input to grep. Multiple patterns are
261 Specify how multiple patterns are combined using Boolean
262 expressions. `--or` is the default operator. `--and` has
263 higher precedence than `--or`. `-e` has to be used for all
267 When giving multiple pattern expressions combined with `--or`,
268 this flag is specified to limit the match to files that
269 have lines to match all of them.
273 Do not output matched lines; instead, exit with status 0 when
274 there is a match and with non-zero status when there isn't.
277 Instead of searching tracked files in the working tree, search
278 blobs in the given trees.
281 Signals the end of options; the rest of the parameters
282 are <pathspec> limiters.
285 If given, limit the search to paths matching at least one pattern.
286 Both leading paths match and glob(7) patterns are supported.
291 `git grep 'time_t' -- '*.[ch]'`::
292 Looks for `time_t` in all tracked .c and .h files in the working
293 directory and its subdirectories.
295 `git grep -e '#define' --and \( -e MAX_PATH -e PATH_MAX \)`::
296 Looks for a line that has `#define` and either `MAX_PATH` or
299 `git grep --all-match -e NODE -e Unexpected`::
300 Looks for a line that has `NODE` or `Unexpected` in
301 files that have lines that match both.
