34 Look for specified patterns in the tracked files in the work tree, blobs
35 registered in the index file, or blobs in given tree objects. Patterns
36 are lists of one or more search expressions separated by newline
37 characters. An empty string as search expression matches all lines.
44 If set to true, enable '-n' option by default.
47 Set the default matching behavior. Using a value of 'basic', 'extended',
48 'fixed', or 'perl' will enable the '--basic-regexp', '--extended-regexp',
49 '--fixed-strings', or '--perl-regexp' option accordingly, while the
50 value 'default' will return to the default matching behavior.
53 If set to true, enable '--extended-regexp' option by default. This
54 option is ignored when the 'grep.patternType' option is set to a value
58 Number of grep worker threads to use. If unset (or set to 0),
59 8 threads are used by default (for now).
62 If set to true, enable '--full-name' option by default.
64 grep.fallbackToNoIndex::
65 If set to true, fall back to git grep --no-index if git grep
66 is executed outside of a git repository. Defaults to false.
72 Instead of searching tracked files in the working tree, search
73 blobs registered in the index file.
76 Synonym for `--cached`.
79 Search files in the current directory that is not managed by Git.
82 In addition to searching in the tracked files in the working
83 tree, search also in untracked files.
85 --no-exclude-standard::
86 Also search in ignored files by not honoring the `.gitignore`
87 mechanism. Only useful with `--untracked`.
90 Do not pay attention to ignored files specified via the `.gitignore`
91 mechanism. Only useful when searching files in the current directory
96 Process binary files as if they were text.
99 Honor textconv filter settings.
102 Do not honor textconv filter settings.
107 Ignore case differences between the patterns and the
111 Don't match the pattern in binary files.
113 --max-depth <depth>::
114 For each <pathspec> given on command line, descend at most <depth>
115 levels of directories. A negative value means no limit.
116 This option is ignored if <pathspec> contains active wildcards.
117 In other words if "a*" matches a directory named "a*",
118 "*" is matched literally so --max-depth is still effective.
122 Match the pattern only at word boundary (either begin at the
123 beginning of a line, or preceded by a non-word character; end at
124 the end of a line or followed by a non-word character).
128 Select non-matching lines.
132 By default, the command shows the filename for each
133 match. `-h` option is used to suppress this output.
134 `-H` is there for completeness and does not do anything
135 except it overrides `-h` given earlier on the command
139 When run from a subdirectory, the command usually
140 outputs paths relative to the current directory. This
141 option forces paths to be output relative to the project
148 Use POSIX extended/basic regexp for patterns. Default
149 is to use basic regexp.
153 Use Perl-compatible regexp for patterns. Requires libpcre to be
158 Use fixed strings for patterns (don't interpret pattern
163 Prefix the line number to matching lines.
166 --files-with-matches::
169 --files-without-match::
170 Instead of showing every matched line, show only the
171 names of files that contain (or do not contain) matches.
172 For better compatibility with 'git diff', `--name-only` is a
173 synonym for `--files-with-matches`.
176 --open-files-in-pager[=<pager>]::
177 Open the matching files in the pager (not the output of 'grep').
178 If the pager happens to be "less" or "vi", and the user
179 specified only one pattern, the first file is positioned at
180 the first match automatically. The `pager` argument is
181 optional; if specified, it must be stuck to the option
182 without a space. If `pager` is unspecified, the default pager
183 will be used (see `core.pager` in linkgit:git-config[1]).
187 Output \0 instead of the character that normally follows a
192 Instead of showing every matched line, show the number of
196 Show colored matches.
197 The value must be always (the default), never, or auto.
200 Turn off match highlighting, even when the configuration file
201 gives the default to color output.
202 Same as `--color=never`.
205 Print an empty line between matches from different files.
208 Show the filename above the matches in that file instead of
209 at the start of each shown line.
213 Show the preceding line that contains the function name of
214 the match, unless the matching line is a function name itself.
215 The name is determined in the same way as 'git diff' works out
216 patch hunk headers (see 'Defining a custom hunk-header' in
217 linkgit:gitattributes[5]).
222 Show <num> leading and trailing lines, and place a line
223 containing `--` between contiguous groups of matches.
226 --after-context <num>::
227 Show <num> trailing lines, and place a line containing
228 `--` between contiguous groups of matches.
231 --before-context <num>::
232 Show <num> leading lines, and place a line containing
233 `--` between contiguous groups of matches.
237 Show the surrounding text from the previous line containing a
238 function name up to the one before the next function name,
239 effectively showing the whole function in which the match was
243 Number of grep worker threads to use.
244 See `grep.threads` in 'CONFIGURATION' for more information.
247 Read patterns from <file>, one per line.
250 The next parameter is the pattern. This option has to be
251 used for patterns starting with `-` and should be used in
252 scripts passing user input to grep. Multiple patterns are
259 Specify how multiple patterns are combined using Boolean
260 expressions. `--or` is the default operator. `--and` has
261 higher precedence than `--or`. `-e` has to be used for all
265 When giving multiple pattern expressions combined with `--or`,
266 this flag is specified to limit the match to files that
267 have lines to match all of them.
271 Do not output matched lines; instead, exit with status 0 when
272 there is a match and with non-zero status when there isn't.
275 Instead of searching tracked files in the working tree, search
276 blobs in the given trees.
279 Signals the end of options; the rest of the parameters
280 are <pathspec> limiters.
283 If given, limit the search to paths matching at least one pattern.
284 Both leading paths match and glob(7) patterns are supported.
289 `git grep 'time_t' -- '*.[ch]'`::
290 Looks for `time_t` in all tracked .c and .h files in the working
291 directory and its subdirectories.
293 `git grep -e '#define' --and \( -e MAX_PATH -e PATH_MAX \)`::
294 Looks for a line that has `#define` and either `MAX_PATH` or
297 `git grep --all-match -e NODE -e Unexpected`::
298 Looks for a line that has `NODE` or `Unexpected` in
299 files that have lines that match both.
