25 DESCRIPTION
26 -----------
27 Look for specified patterns in the working tree files, blobs
28 registered in the index file, or given tree objects.
31 OPTIONS
32 -------
33 --cached::
34 Instead of searching in the working tree files, check
35 the blobs registered in the index file.
37 -a::
38 --text::
39 Process binary files as if they were text.
41 -i::
42 --ignore-case::
43 Ignore case differences between the patterns and the
44 files.
46 -I::
47 Don't match the pattern in binary files.
49 -w::
50 --word-regexp::
51 Match the pattern only at word boundary (either begin at the
52 beginning of a line, or preceded by a non-word character; end at
53 the end of a line or followed by a non-word character).
55 -v::
56 --invert-match::
57 Select non-matching lines.
59 -h::
60 -H::
61 By default, the command shows the filename for each
62 match. `-h` option is used to suppress this output.
63 `-H` is there for completeness and does not do anything
64 except it overrides `-h` given earlier on the command
65 line.
67 --full-name::
68 When run from a subdirectory, the command usually
69 outputs paths relative to the current directory. This
70 option forces paths to be output relative to the project
71 top directory.
73 -E::
74 --extended-regexp::
75 -G::
76 --basic-regexp::
77 Use POSIX extended/basic regexp for patterns. Default
78 is to use basic regexp.
80 -F::
81 --fixed-strings::
82 Use fixed strings for patterns (don't interpret pattern
83 as a regex).
85 -n::
86 Prefix the line number to matching lines.
88 -l::
89 --files-with-matches::
90 --name-only::
91 -L::
92 --files-without-match::
93 Instead of showing every matched line, show only the
94 names of files that contain (or do not contain) matches.
95 For better compatibility with 'git-diff', --name-only is a
96 synonym for --files-with-matches.
98 -z::
99 --null::
100 Output \0 instead of the character that normally follows a
101 file name.
103 -c::
104 --count::
105 Instead of showing every matched line, show the number of
106 lines that match.
108 -[ABC] <context>::
109 Show `context` trailing (`A` -- after), or leading (`B`
110 -- before), or both (`C` -- context) lines, and place a
111 line containing `--` between contiguous groups of
112 matches.
114 -<num>::
115 A shortcut for specifying -C<num>.
117 -f <file>::
118 Read patterns from <file>, one per line.
120 -e::
121 The next parameter is the pattern. This option has to be
122 used for patterns starting with - and should be used in
123 scripts passing user input to grep. Multiple patterns are
124 combined by 'or'.
126 --and::
127 --or::
128 --not::
129 ( ... )::
130 Specify how multiple patterns are combined using Boolean
131 expressions. `--or` is the default operator. `--and` has
132 higher precedence than `--or`. `-e` has to be used for all
133 patterns.
135 --all-match::
136 When giving multiple pattern expressions combined with `--or`,
137 this flag is specified to limit the match to files that
138 have lines to match all of them.
140 `<tree>...`::
141 Search blobs in the trees for specified patterns.
143 \--::
144 Signals the end of options; the rest of the parameters
145 are <path> limiters.
148 Example
149 -------
151 git grep -e \'#define\' --and \( -e MAX_PATH -e PATH_MAX \)::
152 Looks for a line that has `#define` and either `MAX_PATH` or
153 `PATH_MAX`.
155 git grep --all-match -e NODE -e Unexpected::
156 Looks for a line that has `NODE` or `Unexpected` in
157 files that have lines that match both.
