  26 DESCRIPTION
  27 -----------
  28 Look for specified patterns in the working tree files, blobs
  29 registered in the index file, or given tree objects.
  30
  31
  32 OPTIONS
  33 -------
  34 --cached::
  35         Instead of searching in the working tree files, check
  36         the blobs registered in the index file.
  37
  38 -a::
  39 --text::
  40         Process binary files as if they were text.
  41
  42 -i::
  43 --ignore-case::
  44         Ignore case differences between the patterns and the
  45         files.
  46
  47 -I::
  48         Don't match the pattern in binary files.
  49
  50 -w::
  51 --word-regexp::
  52         Match the pattern only at word boundary (either begin at the
  53         beginning of a line, or preceded by a non-word character; end at
  54         the end of a line or followed by a non-word character).
  55
  56 -v::
  57 --invert-match::
  58         Select non-matching lines.
  59
  60 -h::
  61 -H::
  62         By default, the command shows the filename for each
  63         match.  `-h` option is used to suppress this output.
  64         `-H` is there for completeness and does not do anything
  65         except it overrides `-h` given earlier on the command
  66         line.
  67
  68 --full-name::
  69         When run from a subdirectory, the command usually
  70         outputs paths relative to the current directory.  This
  71         option forces paths to be output relative to the project
  72         top directory.
  73
  74 -E::
  75 --extended-regexp::
  76 -G::
  77 --basic-regexp::
  78         Use POSIX extended/basic regexp for patterns.  Default
  79         is to use basic regexp.
  80
  81 -F::
  82 --fixed-strings::
  83         Use fixed strings for patterns (don't interpret pattern
  84         as a regex).
  85
  86 -n::
  87         Prefix the line number to matching lines.
  88
  89 -l::
  90 --files-with-matches::
  91 --name-only::
  92 -L::
  93 --files-without-match::
  94         Instead of showing every matched line, show only the
  95         names of files that contain (or do not contain) matches.
  96         For better compatibility with 'git-diff', --name-only is a
  97         synonym for --files-with-matches.
  98
  99 -z::
 100 --null::
 101         Output \0 instead of the character that normally follows a
 102         file name.
 103
 104 -c::
 105 --count::
 106         Instead of showing every matched line, show the number of
 107         lines that match.
 108
 109 --color::
 110         Show colored matches.
 111
 112 --no-color::
 113         Turn off match highlighting, even when the configuration file
 114         gives the default to color output.
 115
 116 -[ABC] <context>::
 117         Show `context` trailing (`A` -- after), or leading (`B`
 118         -- before), or both (`C` -- context) lines, and place a
 119         line containing `--` between contiguous groups of
 120         matches.
 121
 122 -<num>::
 123         A shortcut for specifying -C<num>.
 124
 125 -f <file>::
 126         Read patterns from <file>, one per line.
 127
 128 -e::
 129         The next parameter is the pattern. This option has to be
 130         used for patterns starting with - and should be used in
 131         scripts passing user input to grep.  Multiple patterns are
 132         combined by 'or'.
 133
 134 --and::
 135 --or::
 136 --not::
 137 ( ... )::
 138         Specify how multiple patterns are combined using Boolean
 139         expressions.  `--or` is the default operator.  `--and` has
 140         higher precedence than `--or`.  `-e` has to be used for all
 141         patterns.
 142
 143 --all-match::
 144         When giving multiple pattern expressions combined with `--or`,
 145         this flag is specified to limit the match to files that
 146         have lines to match all of them.
 147
 148 `<tree>...`::
 149         Search blobs in the trees for specified patterns.
 150
 151 \--::
 152         Signals the end of options; the rest of the parameters
 153         are <path> limiters.
 154
 155
 156 Example
 157 -------
 158
 159 git grep -e \'#define\' --and \( -e MAX_PATH -e PATH_MAX \)::
 160         Looks for a line that has `#define` and either `MAX_PATH` or
 161         `PATH_MAX`.
 162
 163 git grep --all-match -e NODE -e Unexpected::
 164         Looks for a line that has `NODE` or `Unexpected` in
 165         files that have lines that match both.
