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
57 If set to true, enable '--full-name' option by default.
63 Instead of searching tracked files in the working tree, search
64 blobs registered in the index file.
67 Search files in the current directory that is not managed by Git.
70 In addition to searching in the tracked files in the working
71 tree, search also in untracked files.
73 --no-exclude-standard::
74 Also search in ignored files by not honoring the `.gitignore`
75 mechanism. Only useful with `--untracked`.
78 Do not pay attention to ignored files specified via the `.gitignore`
79 mechanism. Only useful when searching files in the current directory
84 Process binary files as if they were text.
87 Honor textconv filter settings.
90 Do not honor textconv filter settings.
95 Ignore case differences between the patterns and the
99 Don't match the pattern in binary files.
101 --max-depth <depth>::
102 For each <pathspec> given on command line, descend at most <depth>
103 levels of directories. A negative value means no limit.
104 This option is ignored if <pathspec> contains active wildcards.
105 In other words if "a*" matches a directory named "a*",
106 "*" is matched literally so --max-depth is still effective.
110 Match the pattern only at word boundary (either begin at the
111 beginning of a line, or preceded by a non-word character; end at
112 the end of a line or followed by a non-word character).
116 Select non-matching lines.
120 By default, the command shows the filename for each
121 match. `-h` option is used to suppress this output.
122 `-H` is there for completeness and does not do anything
123 except it overrides `-h` given earlier on the command
127 When run from a subdirectory, the command usually
128 outputs paths relative to the current directory. This
129 option forces paths to be output relative to the project
136 Use POSIX extended/basic regexp for patterns. Default
137 is to use basic regexp.
141 Use Perl-compatible regexp for patterns. Requires libpcre to be
146 Use fixed strings for patterns (don't interpret pattern
151 Prefix the line number to matching lines.
154 --files-with-matches::
157 --files-without-match::
158 Instead of showing every matched line, show only the
159 names of files that contain (or do not contain) matches.
160 For better compatibility with 'git diff', `--name-only` is a
161 synonym for `--files-with-matches`.
164 --open-files-in-pager [<pager>]::
165 Open the matching files in the pager (not the output of 'grep').
166 If the pager happens to be "less" or "vi", and the user
167 specified only one pattern, the first file is positioned at
168 the first match automatically.
172 Output \0 instead of the character that normally follows a
177 Instead of showing every matched line, show the number of
181 Show colored matches.
182 The value must be always (the default), never, or auto.
185 Turn off match highlighting, even when the configuration file
186 gives the default to color output.
187 Same as `--color=never`.
190 Print an empty line between matches from different files.
193 Show the filename above the matches in that file instead of
194 at the start of each shown line.
198 Show the preceding line that contains the function name of
199 the match, unless the matching line is a function name itself.
200 The name is determined in the same way as 'git diff' works out
201 patch hunk headers (see 'Defining a custom hunk-header' in
202 linkgit:gitattributes[5]).
207 Show <num> leading and trailing lines, and place a line
208 containing `--` between contiguous groups of matches.
211 --after-context <num>::
212 Show <num> trailing lines, and place a line containing
213 `--` between contiguous groups of matches.
216 --before-context <num>::
217 Show <num> leading lines, and place a line containing
218 `--` between contiguous groups of matches.
222 Show the surrounding text from the previous line containing a
223 function name up to the one before the next function name,
224 effectively showing the whole function in which the match was
228 Read patterns from <file>, one per line.
231 The next parameter is the pattern. This option has to be
232 used for patterns starting with `-` and should be used in
233 scripts passing user input to grep. Multiple patterns are
240 Specify how multiple patterns are combined using Boolean
241 expressions. `--or` is the default operator. `--and` has
242 higher precedence than `--or`. `-e` has to be used for all
246 When giving multiple pattern expressions combined with `--or`,
247 this flag is specified to limit the match to files that
248 have lines to match all of them.
252 Do not output matched lines; instead, exit with status 0 when
253 there is a match and with non-zero status when there isn't.
256 Instead of searching tracked files in the working tree, search
257 blobs in the given trees.
260 Signals the end of options; the rest of the parameters
261 are <pathspec> limiters.
264 If given, limit the search to paths matching at least one pattern.
265 Both leading paths match and glob(7) patterns are supported.
270 `git grep 'time_t' -- '*.[ch]'`::
271 Looks for `time_t` in all tracked .c and .h files in the working
272 directory and its subdirectories.
274 `git grep -e '#define' --and \( -e MAX_PATH -e PATH_MAX \)`::
275 Looks for a line that has `#define` and either `MAX_PATH` or
278 `git grep --all-match -e NODE -e Unexpected`::
279 Looks for a line that has `NODE` or `Unexpected` in
280 files that have lines that match both.
