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.
39 If set to true, enable '-n' option by default.
42 If set to true, enable '--extended-regexp' option by default.
48 Instead of searching tracked files in the working tree, search
49 blobs registered in the index file.
52 Search files in the current directory, not just those tracked by git.
56 Process binary files as if they were text.
60 Ignore case differences between the patterns and the
64 Don't match the pattern in binary files.
67 For each <pathspec> given on command line, descend at most <depth>
68 levels of directories. A negative value means no limit.
72 Match the pattern only at word boundary (either begin at the
73 beginning of a line, or preceded by a non-word character; end at
74 the end of a line or followed by a non-word character).
78 Select non-matching lines.
82 By default, the command shows the filename for each
83 match. `-h` option is used to suppress this output.
84 `-H` is there for completeness and does not do anything
85 except it overrides `-h` given earlier on the command
89 When run from a subdirectory, the command usually
90 outputs paths relative to the current directory. This
91 option forces paths to be output relative to the project
98 Use POSIX extended/basic regexp for patterns. Default
99 is to use basic regexp.
103 Use Perl-compatible regexp for patterns. Requires libpcre to be
108 Use fixed strings for patterns (don't interpret pattern
113 Prefix the line number to matching lines.
116 --files-with-matches::
119 --files-without-match::
120 Instead of showing every matched line, show only the
121 names of files that contain (or do not contain) matches.
122 For better compatibility with 'git diff', `--name-only` is a
123 synonym for `--files-with-matches`.
126 --open-files-in-pager [<pager>]::
127 Open the matching files in the pager (not the output of 'grep').
128 If the pager happens to be "less" or "vi", and the user
129 specified only one pattern, the first file is positioned at
130 the first match automatically.
134 Output \0 instead of the character that normally follows a
139 Instead of showing every matched line, show the number of
143 Show colored matches.
144 The value must be always (the default), never, or auto.
147 Turn off match highlighting, even when the configuration file
148 gives the default to color output.
149 Same as `--color=never`.
152 Show `context` trailing (`A` -- after), or leading (`B`
153 -- before), or both (`C` -- context) lines, and place a
154 line containing `--` between contiguous groups of
158 A shortcut for specifying `-C<num>`.
162 Show the preceding line that contains the function name of
163 the match, unless the matching line is a function name itself.
164 The name is determined in the same way as 'git diff' works out
165 patch hunk headers (see 'Defining a custom hunk-header' in
166 linkgit:gitattributes[5]).
169 Read patterns from <file>, one per line.
172 The next parameter is the pattern. This option has to be
173 used for patterns starting with `-` and should be used in
174 scripts passing user input to grep. Multiple patterns are
181 Specify how multiple patterns are combined using Boolean
182 expressions. `--or` is the default operator. `--and` has
183 higher precedence than `--or`. `-e` has to be used for all
187 When giving multiple pattern expressions combined with `--or`,
188 this flag is specified to limit the match to files that
189 have lines to match all of them.
193 Do not output matched lines; instead, exit with status 0 when
194 there is a match and with non-zero status when there isn't.
197 Instead of searching tracked files in the working tree, search
198 blobs in the given trees.
201 Signals the end of options; the rest of the parameters
202 are <pathspec> limiters.
205 If given, limit the search to paths matching at least one pattern.
206 Both leading paths match and glob(7) patterns are supported.
211 git grep {apostrophe}time_t{apostrophe} \-- {apostrophe}*.[ch]{apostrophe}::
212 Looks for `time_t` in all tracked .c and .h files in the working
213 directory and its subdirectories.
215 git grep -e {apostrophe}#define{apostrophe} --and \( -e MAX_PATH -e PATH_MAX \)::
216 Looks for a line that has `#define` and either `MAX_PATH` or
219 git grep --all-match -e NODE -e Unexpected::
220 Looks for a line that has `NODE` or `Unexpected` in
221 files that have lines that match both.
