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 If set to true, enable '--extended-regexp' option by default.
52 Instead of searching tracked files in the working tree, search
53 blobs registered in the index file.
56 Search files in the current directory that is not managed by git.
59 In addition to searching in the tracked files in the working
60 tree, search also in untracked files.
62 --no-exclude-standard::
63 Also search in ignored files by not honoring the `.gitignore`
64 mechanism. Only useful with `--untracked`.
67 Do not pay attention to ignored files specified via the `.gitignore`
68 mechanism. Only useful when searching files in the current directory
73 Process binary files as if they were text.
77 Ignore case differences between the patterns and the
81 Don't match the pattern in binary files.
84 For each <pathspec> given on command line, descend at most <depth>
85 levels of directories. A negative value means no limit.
86 This option is ignored if <pathspec> contains active wildcards.
87 In other words if "a*" matches a directory named "a*",
88 "*" is matched literally so --max-depth is still effective.
92 Match the pattern only at word boundary (either begin at the
93 beginning of a line, or preceded by a non-word character; end at
94 the end of a line or followed by a non-word character).
98 Select non-matching lines.
102 By default, the command shows the filename for each
103 match. `-h` option is used to suppress this output.
104 `-H` is there for completeness and does not do anything
105 except it overrides `-h` given earlier on the command
109 When run from a subdirectory, the command usually
110 outputs paths relative to the current directory. This
111 option forces paths to be output relative to the project
118 Use POSIX extended/basic regexp for patterns. Default
119 is to use basic regexp.
123 Use Perl-compatible regexp for patterns. Requires libpcre to be
128 Use fixed strings for patterns (don't interpret pattern
133 Prefix the line number to matching lines.
136 --files-with-matches::
139 --files-without-match::
140 Instead of showing every matched line, show only the
141 names of files that contain (or do not contain) matches.
142 For better compatibility with 'git diff', `--name-only` is a
143 synonym for `--files-with-matches`.
146 --open-files-in-pager [<pager>]::
147 Open the matching files in the pager (not the output of 'grep').
148 If the pager happens to be "less" or "vi", and the user
149 specified only one pattern, the first file is positioned at
150 the first match automatically.
154 Output \0 instead of the character that normally follows a
159 Instead of showing every matched line, show the number of
163 Show colored matches.
164 The value must be always (the default), never, or auto.
167 Turn off match highlighting, even when the configuration file
168 gives the default to color output.
169 Same as `--color=never`.
172 Print an empty line between matches from different files.
175 Show the filename above the matches in that file instead of
176 at the start of each shown line.
180 Show the preceding line that contains the function name of
181 the match, unless the matching line is a function name itself.
182 The name is determined in the same way as 'git diff' works out
183 patch hunk headers (see 'Defining a custom hunk-header' in
184 linkgit:gitattributes[5]).
189 Show <num> leading and trailing lines, and place a line
190 containing `--` between contiguous groups of matches.
193 --after-context <num>::
194 Show <num> trailing lines, and place a line containing
195 `--` between contiguous groups of matches.
198 --before-context <num>::
199 Show <num> leading lines, and place a line containing
200 `--` between contiguous groups of matches.
204 Show the surrounding text from the previous line containing a
205 function name up to the one before the next function name,
206 effectively showing the whole function in which the match was
210 Read patterns from <file>, one per line.
213 The next parameter is the pattern. This option has to be
214 used for patterns starting with `-` and should be used in
215 scripts passing user input to grep. Multiple patterns are
222 Specify how multiple patterns are combined using Boolean
223 expressions. `--or` is the default operator. `--and` has
224 higher precedence than `--or`. `-e` has to be used for all
228 When giving multiple pattern expressions combined with `--or`,
229 this flag is specified to limit the match to files that
230 have lines to match all of them.
234 Do not output matched lines; instead, exit with status 0 when
235 there is a match and with non-zero status when there isn't.
238 Instead of searching tracked files in the working tree, search
239 blobs in the given trees.
242 Signals the end of options; the rest of the parameters
243 are <pathspec> limiters.
246 If given, limit the search to paths matching at least one pattern.
247 Both leading paths match and glob(7) patterns are supported.
252 `git grep 'time_t' -- '*.[ch]'`::
253 Looks for `time_t` in all tracked .c and .h files in the working
254 directory and its subdirectories.
256 `git grep -e '#define' --and \( -e MAX_PATH -e PATH_MAX \)`::
257 Looks for a line that has `#define` and either `MAX_PATH` or
260 `git grep --all-match -e NODE -e Unexpected`::
261 Looks for a line that has `NODE` or `Unexpected` in
262 files that have lines that match both.
