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.
41 If set to true, enable '-n' option by default.
44 If set to true, enable '--extended-regexp' option by default.
50 Instead of searching tracked files in the working tree, search
51 blobs registered in the index file.
54 Search files in the current directory that is not managed by git.
57 In addition to searching in the tracked files in the working
58 tree, search also in untracked files.
60 --no-exclude-standard::
61 Also search in ignored files by not honoring the `.gitignore`
62 mechanism. Only useful with `--untracked`.
65 Do not pay attention to ignored files specified via the `.gitignore`
66 mechanism. Only useful when searching files in the current directory
71 Process binary files as if they were text.
75 Ignore case differences between the patterns and the
79 Don't match the pattern in binary files.
82 For each <pathspec> given on command line, descend at most <depth>
83 levels of directories. A negative value means no limit.
84 This option is ignored if <pathspec> contains active wildcards.
85 In other words if "a*" matches a directory named "a*",
86 "*" is matched literally so --max-depth is still effective.
90 Match the pattern only at word boundary (either begin at the
91 beginning of a line, or preceded by a non-word character; end at
92 the end of a line or followed by a non-word character).
96 Select non-matching lines.
100 By default, the command shows the filename for each
101 match. `-h` option is used to suppress this output.
102 `-H` is there for completeness and does not do anything
103 except it overrides `-h` given earlier on the command
107 When run from a subdirectory, the command usually
108 outputs paths relative to the current directory. This
109 option forces paths to be output relative to the project
116 Use POSIX extended/basic regexp for patterns. Default
117 is to use basic regexp.
121 Use Perl-compatible regexp for patterns. Requires libpcre to be
126 Use fixed strings for patterns (don't interpret pattern
131 Prefix the line number to matching lines.
134 --files-with-matches::
137 --files-without-match::
138 Instead of showing every matched line, show only the
139 names of files that contain (or do not contain) matches.
140 For better compatibility with 'git diff', `--name-only` is a
141 synonym for `--files-with-matches`.
144 --open-files-in-pager [<pager>]::
145 Open the matching files in the pager (not the output of 'grep').
146 If the pager happens to be "less" or "vi", and the user
147 specified only one pattern, the first file is positioned at
148 the first match automatically.
152 Output \0 instead of the character that normally follows a
157 Instead of showing every matched line, show the number of
161 Show colored matches.
162 The value must be always (the default), never, or auto.
165 Turn off match highlighting, even when the configuration file
166 gives the default to color output.
167 Same as `--color=never`.
170 Print an empty line between matches from different files.
173 Show the filename above the matches in that file instead of
174 at the start of each shown line.
178 Show the preceding line that contains the function name of
179 the match, unless the matching line is a function name itself.
180 The name is determined in the same way as 'git diff' works out
181 patch hunk headers (see 'Defining a custom hunk-header' in
182 linkgit:gitattributes[5]).
187 Show <num> leading and trailing lines, and place a line
188 containing `--` between contiguous groups of matches.
191 --after-context <num>::
192 Show <num> trailing lines, and place a line containing
193 `--` between contiguous groups of matches.
196 --before-context <num>::
197 Show <num> leading lines, and place a line containing
198 `--` between contiguous groups of matches.
202 Show the surrounding text from the previous line containing a
203 function name up to the one before the next function name,
204 effectively showing the whole function in which the match was
208 Read patterns from <file>, one per line.
211 The next parameter is the pattern. This option has to be
212 used for patterns starting with `-` and should be used in
213 scripts passing user input to grep. Multiple patterns are
220 Specify how multiple patterns are combined using Boolean
221 expressions. `--or` is the default operator. `--and` has
222 higher precedence than `--or`. `-e` has to be used for all
226 When giving multiple pattern expressions combined with `--or`,
227 this flag is specified to limit the match to files that
228 have lines to match all of them.
232 Do not output matched lines; instead, exit with status 0 when
233 there is a match and with non-zero status when there isn't.
236 Instead of searching tracked files in the working tree, search
237 blobs in the given trees.
240 Signals the end of options; the rest of the parameters
241 are <pathspec> limiters.
244 If given, limit the search to paths matching at least one pattern.
245 Both leading paths match and glob(7) patterns are supported.
250 `git grep 'time_t' -- '*.[ch]'`::
251 Looks for `time_t` in all tracked .c and .h files in the working
252 directory and its subdirectories.
254 `git grep -e '#define' --and \( -e MAX_PATH -e PATH_MAX \)`::
255 Looks for a line that has `#define` and either `MAX_PATH` or
258 `git grep --all-match -e NODE -e Unexpected`::
259 Looks for a line that has `NODE` or `Unexpected` in
260 files that have lines that match both.
