31 | DESCRIPTION | |
32 | ----------- | |
3ac44408 | 33 | Look for specified patterns in the tracked files in the work tree, blobs |
526a858a RS |
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. | |

39 | CONFIGURATION |
40 | ------------- | |
41 | ||
42 | grep.lineNumber:: | |
43 | If set to true, enable '-n' option by default. | |
44 | ||
84befcd0 S |
45 | grep.patternType:: |
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. | |
50 | ||
b22520a3 | 51 | grep.extendedRegexp:: |
84befcd0 S |
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 | |
54 | other than 'default'. | |
b22520a3 | 55 | |
6453f7b3 AS |
56 | grep.fullName:: |
57 | If set to true, enable '--full-name' option by default. | |

60 | OPTIONS |
61 | ------- | |
1c57119c | 62 | --cached:: |
2e48fcdb ML |
63 | Instead of searching tracked files in the working tree, search |
64 | blobs registered in the index file. | |
65 | ||
66 | --no-index:: | |
2de9b711 | 67 | Search files in the current directory that is not managed by Git. |
1c57119c | 68 | |
0a93fb8a JH |
69 | --untracked:: |
70 | In addition to searching in the tracked files in the working | |
71 | tree, search also in untracked files. | |
72 | ||
73 | --no-exclude-standard:: | |
74 | Also search in ignored files by not honoring the `.gitignore` | |
75 | mechanism. Only useful with `--untracked`. | |
76 | ||
77 | --exclude-standard:: | |
78 | Do not pay attention to ignored files specified via the `.gitignore` | |
79 | mechanism. Only useful when searching files in the current directory | |
80 | with `--no-index`. | |
1c57119c | 81 | |
3240240f SB |
82 | -a:: |
83 | --text:: | |
1c57119c JH |
84 | Process binary files as if they were text. |
85 | ||
335ec3bf JK |
86 | --textconv:: |
87 | Honor textconv filter settings. | |
88 | ||
89 | --no-textconv:: | |
90 | Do not honor textconv filter settings. | |
91 | This is the default. | |
92 | ||
3240240f SB |
93 | -i:: |
94 | --ignore-case:: | |
1c57119c JH |
95 | Ignore case differences between the patterns and the |
96 | files. | |
97 | ||
cf0d720b AR |
98 | -I:: |
99 | Don't match the pattern in binary files. | |
100 | ||
a91f453f | 101 | --max-depth <depth>:: |
3ac44408 | 102 | For each <pathspec> given on command line, descend at most <depth> |
a91f453f | 103 | levels of directories. A negative value means no limit. |
8c69c1f9 NTND |
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. | |
a91f453f | 107 | |
3240240f SB |
108 | -w:: |
109 | --word-regexp:: | |
1c57119c JH |
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). | |
113 | ||
3240240f SB |
114 | -v:: |
115 | --invert-match:: | |
1c57119c JH |
116 | Select non-matching lines. |
117 | ||
3240240f SB |
118 | -h:: |
119 | -H:: | |
17fd965d JH |
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 | |
124 | line. | |
125 | ||
0d042fec JH |
126 | --full-name:: |
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 | |
130 | top directory. | |
131 | ||
3240240f SB |
132 | -E:: |
133 | --extended-regexp:: | |
134 | -G:: | |
135 | --basic-regexp:: | |
1c57119c JH |
136 | Use POSIX extended/basic regexp for patterns. Default |
137 | is to use basic regexp. | |
5b2bcc7b | 138 | |
63e7e9d8 MK |
139 | -P:: |
140 | --perl-regexp:: | |
141 | Use Perl-compatible regexp for patterns. Requires libpcre to be | |
142 | compiled in. | |
143 | ||
3240240f SB |
144 | -F:: |
145 | --fixed-strings:: | |
cf0d720b AR |
146 | Use fixed strings for patterns (don't interpret pattern |
147 | as a regex). | |
148 | ||
1c57119c | 149 | -n:: |
7d6cb10b | 150 | --line-number:: |
1c57119c | 151 | Prefix the line number to matching lines. |
2aba319a | 152 | |
3240240f SB |
153 | -l:: |
154 | --files-with-matches:: | |
155 | --name-only:: | |
156 | -L:: | |
157 | --files-without-match:: | |
1c57119c JH |
158 | Instead of showing every matched line, show only the |
159 | names of files that contain (or do not contain) matches. | |
bfb8306d ML |
160 | For better compatibility with 'git diff', `--name-only` is a |
161 | synonym for `--files-with-matches`. | |
2aba319a | 162 | |
0af88c15 JS |
163 | -O [<pager>]:: |
164 | --open-files-in-pager [<pager>]:: | |
678e484b JS |
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. | |
169 | ||
83caecca RZ |
170 | -z:: |
171 | --null:: | |
172 | Output \0 instead of the character that normally follows a | |
173 | file name. | |
174 | ||
3240240f SB |
175 | -c:: |
176 | --count:: | |
1c57119c JH |
177 | Instead of showing every matched line, show the number of |
178 | lines that match. | |
179 | ||
73e9da01 | 180 | --color[=<when>]:: |
7e8f59d5 | 181 | Show colored matches. |
73e9da01 | 182 | The value must be always (the default), never, or auto. |
7e8f59d5 RS |
183 | |
184 | --no-color:: | |
185 | Turn off match highlighting, even when the configuration file | |
186 | gives the default to color output. | |
73e9da01 | 187 | Same as `--color=never`. |
7e8f59d5 | 188 | |
a8f0e764 RS |
189 | --break:: |
190 | Print an empty line between matches from different files. | |
191 | ||
1d84f72e RS |
192 | --heading:: |
193 | Show the filename above the matches in that file instead of | |
194 | at the start of each shown line. | |
195 | ||
2944e4e6 RS |
196 | -p:: |
197 | --show-function:: | |
198 | Show the preceding line that contains the function name of | |
199 | the match, unless the matching line is a function name itself. | |
60ecac98 RS |
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]). | |
2944e4e6 | 203 | |
317f63c2 RS |
204 | -<num>:: |
205 | -C <num>:: | |
206 | --context <num>:: | |
207 | Show <num> leading and trailing lines, and place a line | |
208 | containing `--` between contiguous groups of matches. | |
209 | ||
210 | -A <num>:: | |
211 | --after-context <num>:: | |
212 | Show <num> trailing lines, and place a line containing | |
213 | `--` between contiguous groups of matches. | |
214 | ||
215 | -B <num>:: | |
216 | --before-context <num>:: | |
217 | Show <num> leading lines, and place a line containing | |
218 | `--` between contiguous groups of matches. | |
219 | ||
ba8ea749 | 220 | -W:: |
317f63c2 | 221 | --function-context:: |
ba8ea749 RS |
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 | |
225 | found. | |
226 | ||
1c57119c JH |
227 | -f <file>:: |
228 | Read patterns from <file>, one per line. | |
229 | ||
3acb27b6 ML |
230 | -e:: |
231 | The next parameter is the pattern. This option has to be | |
bfb8306d | 232 | used for patterns starting with `-` and should be used in |
fba0cbd9 ML |
233 | scripts passing user input to grep. Multiple patterns are |
234 | combined by 'or'. | |
235 | ||
3240240f SB |
236 | --and:: |
237 | --or:: | |
238 | --not:: | |
239 | ( ... ):: | |
23bfbb81 | 240 | Specify how multiple patterns are combined using Boolean |
fba0cbd9 ML |
241 | expressions. `--or` is the default operator. `--and` has |
242 | higher precedence than `--or`. `-e` has to be used for all | |
243 | patterns. | |
3acb27b6 | 244 | |
0ab7befa JH |
245 | --all-match:: |
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. | |
249 | ||
4ff61c21 JH |
250 | -q:: |
251 | --quiet:: | |
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. | |
254 | ||
bfb8306d | 255 | <tree>...:: |
2e48fcdb ML |
256 | Instead of searching tracked files in the working tree, search |
257 | blobs in the given trees. | |
1c57119c | 258 | |
fba0cbd9 | 259 | \--:: |
1c57119c | 260 | Signals the end of options; the rest of the parameters |
3ac44408 | 261 | are <pathspec> limiters. |
2aba319a | 262 | |
3ac44408 ML |
263 | <pathspec>...:: |
264 | If given, limit the search to paths matching at least one pattern. | |
265 | Both leading paths match and glob(7) patterns are supported. | |
2aba319a | 266 | |
04416018 ML |
267 | Examples |
268 | -------- | |
fba0cbd9 | 269 | |
6cf378f0 | 270 | `git grep 'time_t' -- '*.[ch]'`:: |
3ac44408 ML |
271 | Looks for `time_t` in all tracked .c and .h files in the working |
272 | directory and its subdirectories. | |
273 | ||
6cf378f0 | 274 | `git grep -e '#define' --and \( -e MAX_PATH -e PATH_MAX \)`:: |
fba0cbd9 ML |
275 | Looks for a line that has `#define` and either `MAX_PATH` or |
276 | `PATH_MAX`. | |
277 | ||
5d2fc913 | 278 | `git grep --all-match -e NODE -e Unexpected`:: |
0ab7befa JH |
279 | Looks for a line that has `NODE` or `Unexpected` in |
280 | files that have lines that match both. | |
