24 DESCRIPTION
25 -----------
26 Look for specified patterns in the working tree files, blobs
27 registered in the index file, or given tree objects.
30 OPTIONS
31 -------
32 --cached::
33 Instead of searching in the working tree files, check
34 the blobs registered in the index file.
36 -a | --text::
37 Process binary files as if they were text.
39 -i | --ignore-case::
40 Ignore case differences between the patterns and the
41 files.
43 -I::
44 Don't match the pattern in binary files.
46 -w | --word-regexp::
47 Match the pattern only at word boundary (either begin at the
48 beginning of a line, or preceded by a non-word character; end at
49 the end of a line or followed by a non-word character).
51 -v | --invert-match::
52 Select non-matching lines.
54 -h | -H::
55 By default, the command shows the filename for each
56 match. `-h` option is used to suppress this output.
57 `-H` is there for completeness and does not do anything
58 except it overrides `-h` given earlier on the command
59 line.
61 --full-name::
62 When run from a subdirectory, the command usually
63 outputs paths relative to the current directory. This
64 option forces paths to be output relative to the project
65 top directory.
67 -E | --extended-regexp | -G | --basic-regexp::
68 Use POSIX extended/basic regexp for patterns. Default
69 is to use basic regexp.
71 -F | --fixed-strings::
72 Use fixed strings for patterns (don't interpret pattern
73 as a regex).
75 -n::
76 Prefix the line number to matching lines.
78 -l | --files-with-matches | -L | --files-without-match::
79 Instead of showing every matched line, show only the
80 names of files that contain (or do not contain) matches.
82 -c | --count::
83 Instead of showing every matched line, show the number of
84 lines that match.
86 -[ABC] <context>::
87 Show `context` trailing (`A` -- after), or leading (`B`
88 -- before), or both (`C` -- context) lines, and place a
89 line containing `--` between contiguous groups of
90 matches.
92 -<num>::
93 A shortcut for specifying -C<num>.
95 -f <file>::
96 Read patterns from <file>, one per line.
98 -e::
99 The next parameter is the pattern. This option has to be
100 used for patterns starting with - and should be used in
101 scripts passing user input to grep. Multiple patterns are
102 combined by 'or'.
104 --and | --or | --not | ( | )::
105 Specify how multiple patterns are combined using Boolean
106 expressions. `--or` is the default operator. `--and` has
107 higher precedence than `--or`. `-e` has to be used for all
108 patterns.
110 --all-match::
111 When giving multiple pattern expressions combined with `--or`,
112 this flag is specified to limit the match to files that
113 have lines to match all of them.
115 `<tree>...`::
116 Search blobs in the trees for specified patterns.
118 \--::
119 Signals the end of options; the rest of the parameters
120 are <path> limiters.
123 Example
124 -------
126 git grep -e \'#define\' --and \( -e MAX_PATH -e PATH_MAX \)::
127 Looks for a line that has `#define` and either `MAX_PATH` or
128 `PATH_MAX`.
130 git grep --all-match -e NODE -e Unexpected::
131 Looks for a line that has `NODE` or `Unexpected` in
132 files that have lines that match both.
