33 Look for specified patterns in the tracked files in the work tree, blobs
34 registered in the index file, or blobs in given tree objects. Patterns
35 are lists of one or more search expressions separated by newline
36 characters. An empty string as search expression matches all lines.
43 If set to true, enable '-n' option by default.
46 Set the default matching behavior. Using a value of 'basic', 'extended',
47 'fixed', or 'perl' will enable the '--basic-regexp', '--extended-regexp',
48 '--fixed-strings', or '--perl-regexp' option accordingly, while the
49 value 'default' will return to the default matching behavior.
52 If set to true, enable '--extended-regexp' option by default. This
53 option is ignored when the 'grep.patternType' option is set to a value
60 Instead of searching tracked files in the working tree, search
61 blobs registered in the index file.
64 Search files in the current directory that is not managed by Git.
67 In addition to searching in the tracked files in the working
68 tree, search also in untracked files.
70 --no-exclude-standard::
71 Also search in ignored files by not honoring the `.gitignore`
72 mechanism. Only useful with `--untracked`.
75 Do not pay attention to ignored files specified via the `.gitignore`
76 mechanism. Only useful when searching files in the current directory
81 Process binary files as if they were text.
84 Honor textconv filter settings.
87 Do not honor textconv filter settings.
92 Ignore case differences between the patterns and the
96 Don't match the pattern in binary files.
99 For each <pathspec> given on command line, descend at most <depth>
100 levels of directories. A negative value means no limit.
101 This option is ignored if <pathspec> contains active wildcards.
102 In other words if "a*" matches a directory named "a*",
103 "*" is matched literally so --max-depth is still effective.
107 Match the pattern only at word boundary (either begin at the
108 beginning of a line, or preceded by a non-word character; end at
109 the end of a line or followed by a non-word character).
113 Select non-matching lines.
117 By default, the command shows the filename for each
118 match. `-h` option is used to suppress this output.
119 `-H` is there for completeness and does not do anything
120 except it overrides `-h` given earlier on the command
124 When run from a subdirectory, the command usually
125 outputs paths relative to the current directory. This
126 option forces paths to be output relative to the project
133 Use POSIX extended/basic regexp for patterns. Default
134 is to use basic regexp.
138 Use Perl-compatible regexp for patterns. Requires libpcre to be
143 Use fixed strings for patterns (don't interpret pattern
148 Prefix the line number to matching lines.
151 --files-with-matches::
154 --files-without-match::
155 Instead of showing every matched line, show only the
156 names of files that contain (or do not contain) matches.
157 For better compatibility with 'git diff', `--name-only` is a
158 synonym for `--files-with-matches`.
161 --open-files-in-pager [<pager>]::
162 Open the matching files in the pager (not the output of 'grep').
163 If the pager happens to be "less" or "vi", and the user
164 specified only one pattern, the first file is positioned at
165 the first match automatically.
169 Output \0 instead of the character that normally follows a
174 Instead of showing every matched line, show the number of
178 Show colored matches.
179 The value must be always (the default), never, or auto.
182 Turn off match highlighting, even when the configuration file
183 gives the default to color output.
184 Same as `--color=never`.
187 Print an empty line between matches from different files.
190 Show the filename above the matches in that file instead of
191 at the start of each shown line.
195 Show the preceding line that contains the function name of
196 the match, unless the matching line is a function name itself.
197 The name is determined in the same way as 'git diff' works out
198 patch hunk headers (see 'Defining a custom hunk-header' in
199 linkgit:gitattributes[5]).
204 Show <num> leading and trailing lines, and place a line
205 containing `--` between contiguous groups of matches.
208 --after-context <num>::
209 Show <num> trailing lines, and place a line containing
210 `--` between contiguous groups of matches.
213 --before-context <num>::
214 Show <num> leading lines, and place a line containing
215 `--` between contiguous groups of matches.
219 Show the surrounding text from the previous line containing a
220 function name up to the one before the next function name,
221 effectively showing the whole function in which the match was
225 Read patterns from <file>, one per line.
228 The next parameter is the pattern. This option has to be
229 used for patterns starting with `-` and should be used in
230 scripts passing user input to grep. Multiple patterns are
237 Specify how multiple patterns are combined using Boolean
238 expressions. `--or` is the default operator. `--and` has
239 higher precedence than `--or`. `-e` has to be used for all
243 When giving multiple pattern expressions combined with `--or`,
244 this flag is specified to limit the match to files that
245 have lines to match all of them.
249 Do not output matched lines; instead, exit with status 0 when
250 there is a match and with non-zero status when there isn't.
253 Instead of searching tracked files in the working tree, search
254 blobs in the given trees.
257 Signals the end of options; the rest of the parameters
258 are <pathspec> limiters.
261 If given, limit the search to paths matching at least one pattern.
262 Both leading paths match and glob(7) patterns are supported.
267 `git grep 'time_t' -- '*.[ch]'`::
268 Looks for `time_t` in all tracked .c and .h files in the working
269 directory and its subdirectories.
271 `git grep -e '#define' --and \( -e MAX_PATH -e PATH_MAX \)`::
272 Looks for a line that has `#define` and either `MAX_PATH` or
275 `git grep --all-match -e NODE -e Unexpected`::
276 Looks for a line that has `NODE` or `Unexpected` in
277 files that have lines that match both.
