6 git-grep - Print lines matching a pattern
13 [-a | --text] [-I] [-i | --ignore-case] [-w | --word-regexp]
14 [-v | --invert-match] [-h|-H] [--full-name]
15 [-E | --extended-regexp] [-G | --basic-regexp]
16 [-F | --fixed-strings] [-n]
17 [-l | --files-with-matches] [-L | --files-without-match]
18 [-c | --count] [--all-match]
19 [-A <post-context>] [-B <pre-context>] [-C <context>]
20 [-f <file>] [-e] <pattern>
21 [--and|--or|--not|(|)|-e <pattern>...] [<tree>...]
26 Look for specified patterns in the working tree files, blobs
27 registered in the index file, or given tree objects.
33 Instead of searching in the working tree files, check
34 the blobs registered in the index file.
37 Process binary files as if they were text.
40 Ignore case differences between the patterns and the
44 Don't match the pattern in binary files.
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).
52 Select non-matching lines.
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
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
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
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.
83 Instead of showing every matched line, show the number of
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
93 A shortcut for specifying -C<num>.
96 Read patterns from <file>, one per line.
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
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
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.
116 Search blobs in the trees for specified patterns.
119 Signals the end of options; the rest of the parameters
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
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.
