23 [-f <file>] [-e] <pattern>
24 [--and|--or|--not|(|)|-e <pattern>...]
25 [--cached | --no-index | <tree>...]
30 Look for specified patterns in the tracked files in the work tree, blobs
31 registered in the index file, or blobs in given tree objects.
37 Instead of searching tracked files in the working tree, search
38 blobs registered in the index file.
41 Search files in the current directory, not just those tracked by git.
45 Process binary files as if they were text.
49 Ignore case differences between the patterns and the
53 Don't match the pattern in binary files.
56 For each <pathspec> given on command line, descend at most <depth>
57 levels of directories. A negative value means no limit.
61 Match the pattern only at word boundary (either begin at the
62 beginning of a line, or preceded by a non-word character; end at
63 the end of a line or followed by a non-word character).
67 Select non-matching lines.
71 By default, the command shows the filename for each
72 match. `-h` option is used to suppress this output.
73 `-H` is there for completeness and does not do anything
74 except it overrides `-h` given earlier on the command
78 When run from a subdirectory, the command usually
79 outputs paths relative to the current directory. This
80 option forces paths to be output relative to the project
87 Use POSIX extended/basic regexp for patterns. Default
88 is to use basic regexp.
92 Use fixed strings for patterns (don't interpret pattern
97 Prefix the line number to matching lines.
100 --files-with-matches::
103 --files-without-match::
104 Instead of showing every matched line, show only the
105 names of files that contain (or do not contain) matches.
106 For better compatibility with 'git diff', `--name-only` is a
107 synonym for `--files-with-matches`.
110 --open-files-in-pager [<pager>]::
111 Open the matching files in the pager (not the output of 'grep').
112 If the pager happens to be "less" or "vi", and the user
113 specified only one pattern, the first file is positioned at
114 the first match automatically.
118 Output \0 instead of the character that normally follows a
123 Instead of showing every matched line, show the number of
127 Show colored matches.
128 The value must be always (the default), never, or auto.
131 Turn off match highlighting, even when the configuration file
132 gives the default to color output.
133 Same as `--color=never`.
136 Show `context` trailing (`A` -- after), or leading (`B`
137 -- before), or both (`C` -- context) lines, and place a
138 line containing `--` between contiguous groups of
142 A shortcut for specifying `-C<num>`.
146 Show the preceding line that contains the function name of
147 the match, unless the matching line is a function name itself.
148 The name is determined in the same way as 'git diff' works out
149 patch hunk headers (see 'Defining a custom hunk-header' in
150 linkgit:gitattributes[5]).
153 Read patterns from <file>, one per line.
156 The next parameter is the pattern. This option has to be
157 used for patterns starting with `-` and should be used in
158 scripts passing user input to grep. Multiple patterns are
165 Specify how multiple patterns are combined using Boolean
166 expressions. `--or` is the default operator. `--and` has
167 higher precedence than `--or`. `-e` has to be used for all
171 When giving multiple pattern expressions combined with `--or`,
172 this flag is specified to limit the match to files that
173 have lines to match all of them.
177 Do not output matched lines; instead, exit with status 0 when
178 there is a match and with non-zero status when there isn't.
181 Instead of searching tracked files in the working tree, search
182 blobs in the given trees.
185 Signals the end of options; the rest of the parameters
186 are <pathspec> limiters.
189 If given, limit the search to paths matching at least one pattern.
190 Both leading paths match and glob(7) patterns are supported.
195 git grep {apostrophe}time_t{apostrophe} \-- {apostrophe}*.[ch]{apostrophe}::
196 Looks for `time_t` in all tracked .c and .h files in the working
197 directory and its subdirectories.
199 git grep -e {apostrophe}#define{apostrophe} --and \( -e MAX_PATH -e PATH_MAX \)::
200 Looks for a line that has `#define` and either `MAX_PATH` or
203 git grep --all-match -e NODE -e Unexpected::
204 Looks for a line that has `NODE` or `Unexpected` in
205 files that have lines that match both.
