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
60 Instead of searching tracked files in the working tree, search
61 blobs registered in the index file.
64 Search files in the current directory that is not managed by Git.
67 In addition to searching in the tracked files in the working
68 tree, search also in untracked files.
70 --no-exclude-standard::
71 Also search in ignored files by not honoring the `.gitignore`
72 mechanism. Only useful with `--untracked`.
75 Do not pay attention to ignored files specified via the `.gitignore`
76 mechanism. Only useful when searching files in the current directory
81 Process binary files as if they were text.
85 Ignore case differences between the patterns and the
89 Don't match the pattern in binary files.
92 For each <pathspec> given on command line, descend at most <depth>
93 levels of directories. A negative value means no limit.
94 This option is ignored if <pathspec> contains active wildcards.
95 In other words if "a*" matches a directory named "a*",
96 "*" is matched literally so --max-depth is still effective.
100 Match the pattern only at word boundary (either begin at the
101 beginning of a line, or preceded by a non-word character; end at
102 the end of a line or followed by a non-word character).
106 Select non-matching lines.
110 By default, the command shows the filename for each
111 match. `-h` option is used to suppress this output.
112 `-H` is there for completeness and does not do anything
113 except it overrides `-h` given earlier on the command
117 When run from a subdirectory, the command usually
118 outputs paths relative to the current directory. This
119 option forces paths to be output relative to the project
126 Use POSIX extended/basic regexp for patterns. Default
127 is to use basic regexp.
131 Use Perl-compatible regexp for patterns. Requires libpcre to be
136 Use fixed strings for patterns (don't interpret pattern
141 Prefix the line number to matching lines.
144 --files-with-matches::
147 --files-without-match::
148 Instead of showing every matched line, show only the
149 names of files that contain (or do not contain) matches.
150 For better compatibility with 'git diff', `--name-only` is a
151 synonym for `--files-with-matches`.
154 --open-files-in-pager [<pager>]::
155 Open the matching files in the pager (not the output of 'grep').
156 If the pager happens to be "less" or "vi", and the user
157 specified only one pattern, the first file is positioned at
158 the first match automatically.
162 Output \0 instead of the character that normally follows a
167 Instead of showing every matched line, show the number of
171 Show colored matches.
172 The value must be always (the default), never, or auto.
175 Turn off match highlighting, even when the configuration file
176 gives the default to color output.
177 Same as `--color=never`.
180 Print an empty line between matches from different files.
183 Show the filename above the matches in that file instead of
184 at the start of each shown line.
188 Show the preceding line that contains the function name of
189 the match, unless the matching line is a function name itself.
190 The name is determined in the same way as 'git diff' works out
191 patch hunk headers (see 'Defining a custom hunk-header' in
192 linkgit:gitattributes[5]).
197 Show <num> leading and trailing lines, and place a line
198 containing `--` between contiguous groups of matches.
201 --after-context <num>::
202 Show <num> trailing lines, and place a line containing
203 `--` between contiguous groups of matches.
206 --before-context <num>::
207 Show <num> leading lines, and place a line containing
208 `--` between contiguous groups of matches.
212 Show the surrounding text from the previous line containing a
213 function name up to the one before the next function name,
214 effectively showing the whole function in which the match was
218 Read patterns from <file>, one per line.
221 The next parameter is the pattern. This option has to be
222 used for patterns starting with `-` and should be used in
223 scripts passing user input to grep. Multiple patterns are
230 Specify how multiple patterns are combined using Boolean
231 expressions. `--or` is the default operator. `--and` has
232 higher precedence than `--or`. `-e` has to be used for all
236 When giving multiple pattern expressions combined with `--or`,
237 this flag is specified to limit the match to files that
238 have lines to match all of them.
242 Do not output matched lines; instead, exit with status 0 when
243 there is a match and with non-zero status when there isn't.
246 Instead of searching tracked files in the working tree, search
247 blobs in the given trees.
250 Signals the end of options; the rest of the parameters
251 are <pathspec> limiters.
254 If given, limit the search to paths matching at least one pattern.
255 Both leading paths match and glob(7) patterns are supported.
260 `git grep 'time_t' -- '*.[ch]'`::
261 Looks for `time_t` in all tracked .c and .h files in the working
262 directory and its subdirectories.
264 `git grep -e '#define' --and \( -e MAX_PATH -e PATH_MAX \)`::
265 Looks for a line that has `#define` and either `MAX_PATH` or
268 `git grep --all-match -e NODE -e Unexpected`::
269 Looks for a line that has `NODE` or `Unexpected` in
270 files that have lines that match both.
