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 Print an empty line between matches from different files.
155 Show `context` trailing (`A` -- after), or leading (`B`
156 -- before), or both (`C` -- context) lines, and place a
157 line containing `--` between contiguous groups of
161 A shortcut for specifying `-C<num>`.
165 Show the preceding line that contains the function name of
166 the match, unless the matching line is a function name itself.
167 The name is determined in the same way as 'git diff' works out
168 patch hunk headers (see 'Defining a custom hunk-header' in
169 linkgit:gitattributes[5]).
172 Read patterns from <file>, one per line.
175 The next parameter is the pattern. This option has to be
176 used for patterns starting with `-` and should be used in
177 scripts passing user input to grep. Multiple patterns are
184 Specify how multiple patterns are combined using Boolean
185 expressions. `--or` is the default operator. `--and` has
186 higher precedence than `--or`. `-e` has to be used for all
190 When giving multiple pattern expressions combined with `--or`,
191 this flag is specified to limit the match to files that
192 have lines to match all of them.
196 Do not output matched lines; instead, exit with status 0 when
197 there is a match and with non-zero status when there isn't.
200 Instead of searching tracked files in the working tree, search
201 blobs in the given trees.
204 Signals the end of options; the rest of the parameters
205 are <pathspec> limiters.
208 If given, limit the search to paths matching at least one pattern.
209 Both leading paths match and glob(7) patterns are supported.
214 git grep {apostrophe}time_t{apostrophe} \-- {apostrophe}*.[ch]{apostrophe}::
215 Looks for `time_t` in all tracked .c and .h files in the working
216 directory and its subdirectories.
218 git grep -e {apostrophe}#define{apostrophe} --and \( -e MAX_PATH -e PATH_MAX \)::
219 Looks for a line that has `#define` and either `MAX_PATH` or
222 git grep --all-match -e NODE -e Unexpected::
223 Looks for a line that has `NODE` or `Unexpected` in
224 files that have lines that match both.
