29 DESCRIPTION
30 -----------
31 Look for specified patterns in the tracked files in the work tree, blobs
32 registered in the index file, or blobs in given tree objects.
35 CONFIGURATION
36 -------------
38 grep.lineNumber::
39 If set to true, enable '-n' option by default.
41 grep.extendedRegexp::
42 If set to true, enable '--extended-regexp' option by default.
45 OPTIONS
46 -------
47 --cached::
48 Instead of searching tracked files in the working tree, search
49 blobs registered in the index file.
51 --no-index::
52 Search files in the current directory that is not managed by git.
54 --untracked::
55 In addition to searching in the tracked files in the working
56 tree, search also in untracked files.
58 --no-exclude-standard::
59 Also search in ignored files by not honoring the `.gitignore`
60 mechanism. Only useful with `--untracked`.
62 --exclude-standard::
63 Do not pay attention to ignored files specified via the `.gitignore`
64 mechanism. Only useful when searching files in the current directory
65 with `--no-index`.
67 -a::
68 --text::
69 Process binary files as if they were text.
71 -i::
72 --ignore-case::
73 Ignore case differences between the patterns and the
74 files.
76 -I::
77 Don't match the pattern in binary files.
79 --max-depth <depth>::
80 For each <pathspec> given on command line, descend at most <depth>
81 levels of directories. A negative value means no limit.
82 This option is ignored if <pathspec> contains active wildcards.
83 In other words if "a*" matches a directory named "a*",
84 "*" is matched literally so --max-depth is still effective.
86 -w::
87 --word-regexp::
88 Match the pattern only at word boundary (either begin at the
89 beginning of a line, or preceded by a non-word character; end at
90 the end of a line or followed by a non-word character).
92 -v::
93 --invert-match::
94 Select non-matching lines.
96 -h::
97 -H::
98 By default, the command shows the filename for each
99 match. `-h` option is used to suppress this output.
100 `-H` is there for completeness and does not do anything
101 except it overrides `-h` given earlier on the command
102 line.
104 --full-name::
105 When run from a subdirectory, the command usually
106 outputs paths relative to the current directory. This
107 option forces paths to be output relative to the project
108 top directory.
110 -E::
111 --extended-regexp::
112 -G::
113 --basic-regexp::
114 Use POSIX extended/basic regexp for patterns. Default
115 is to use basic regexp.
117 -P::
118 --perl-regexp::
119 Use Perl-compatible regexp for patterns. Requires libpcre to be
120 compiled in.
122 -F::
123 --fixed-strings::
124 Use fixed strings for patterns (don't interpret pattern
125 as a regex).
127 -n::
128 --line-number::
129 Prefix the line number to matching lines.
131 -l::
132 --files-with-matches::
133 --name-only::
134 -L::
135 --files-without-match::
136 Instead of showing every matched line, show only the
137 names of files that contain (or do not contain) matches.
138 For better compatibility with 'git diff', `--name-only` is a
139 synonym for `--files-with-matches`.
141 -O [<pager>]::
142 --open-files-in-pager [<pager>]::
143 Open the matching files in the pager (not the output of 'grep').
144 If the pager happens to be "less" or "vi", and the user
145 specified only one pattern, the first file is positioned at
146 the first match automatically.
148 -z::
149 --null::
150 Output \0 instead of the character that normally follows a
151 file name.
153 -c::
154 --count::
155 Instead of showing every matched line, show the number of
156 lines that match.
158 --color[=<when>]::
159 Show colored matches.
160 The value must be always (the default), never, or auto.
162 --no-color::
163 Turn off match highlighting, even when the configuration file
164 gives the default to color output.
165 Same as `--color=never`.
167 --break::
168 Print an empty line between matches from different files.
170 --heading::
171 Show the filename above the matches in that file instead of
172 at the start of each shown line.
174 -p::
175 --show-function::
176 Show the preceding line that contains the function name of
177 the match, unless the matching line is a function name itself.
178 The name is determined in the same way as 'git diff' works out
179 patch hunk headers (see 'Defining a custom hunk-header' in
180 linkgit:gitattributes[5]).
182 -<num>::
183 -C <num>::
184 --context <num>::
185 Show <num> leading and trailing lines, and place a line
186 containing `--` between contiguous groups of matches.
188 -A <num>::
189 --after-context <num>::
190 Show <num> trailing lines, and place a line containing
191 `--` between contiguous groups of matches.
193 -B <num>::
194 --before-context <num>::
195 Show <num> leading lines, and place a line containing
196 `--` between contiguous groups of matches.
198 -W::
199 --function-context::
200 Show the surrounding text from the previous line containing a
201 function name up to the one before the next function name,
202 effectively showing the whole function in which the match was
203 found.
205 -f <file>::
206 Read patterns from <file>, one per line.
208 -e::
209 The next parameter is the pattern. This option has to be
210 used for patterns starting with `-` and should be used in
211 scripts passing user input to grep. Multiple patterns are
212 combined by 'or'.
214 --and::
215 --or::
216 --not::
217 ( ... )::
218 Specify how multiple patterns are combined using Boolean
219 expressions. `--or` is the default operator. `--and` has
220 higher precedence than `--or`. `-e` has to be used for all
221 patterns.
223 --all-match::
224 When giving multiple pattern expressions combined with `--or`,
225 this flag is specified to limit the match to files that
226 have lines to match all of them.
228 -q::
229 --quiet::
230 Do not output matched lines; instead, exit with status 0 when
231 there is a match and with non-zero status when there isn't.
233 <tree>...::
234 Instead of searching tracked files in the working tree, search
235 blobs in the given trees.
237 \--::
238 Signals the end of options; the rest of the parameters
239 are <pathspec> limiters.
241 <pathspec>...::
242 If given, limit the search to paths matching at least one pattern.
243 Both leading paths match and glob(7) patterns are supported.
245 Examples
246 --------
248 `git grep {apostrophe}time_t{apostrophe} \-- {apostrophe}*.[ch]{apostrophe}`::
249 Looks for `time_t` in all tracked .c and .h files in the working
250 directory and its subdirectories.
252 `git grep -e {apostrophe}#define{apostrophe} --and \( -e MAX_PATH -e PATH_MAX \)`::
253 Looks for a line that has `#define` and either `MAX_PATH` or
254 `PATH_MAX`.
256 `git grep --all-match -e NODE -e Unexpected`::
257 Looks for a line that has `NODE` or `Unexpected` in
258 files that have lines that match both.
