  24 DESCRIPTION
  25 -----------
  26 Look for specified patterns in the working tree files, blobs
  27 registered in the index file, or given tree objects.
  28
  29
  30 OPTIONS
  31 -------
  32 --cached::
  33         Instead of searching in the working tree files, check
  34         the blobs registered in the index file.
  35
  36 -a::
  37 --text::
  38         Process binary files as if they were text.
  39
  40 -i::
  41 --ignore-case::
  42         Ignore case differences between the patterns and the
  43         files.
  44
  45 -I::
  46         Don't match the pattern in binary files.
  47
  48 -w::
  49 --word-regexp::
  50         Match the pattern only at word boundary (either begin at the
  51         beginning of a line, or preceded by a non-word character; end at
  52         the end of a line or followed by a non-word character).
  53
  54 -v::
  55 --invert-match::
  56         Select non-matching lines.
  57
  58 -h::
  59 -H::
  60         By default, the command shows the filename for each
  61         match.  `-h` option is used to suppress this output.
  62         `-H` is there for completeness and does not do anything
  63         except it overrides `-h` given earlier on the command
  64         line.
  65
  66 --full-name::
  67         When run from a subdirectory, the command usually
  68         outputs paths relative to the current directory.  This
  69         option forces paths to be output relative to the project
  70         top directory.
  71
  72 -E::
  73 --extended-regexp::
  74 -G::
  75 --basic-regexp::
  76         Use POSIX extended/basic regexp for patterns.  Default
  77         is to use basic regexp.
  78
  79 -F::
  80 --fixed-strings::
  81         Use fixed strings for patterns (don't interpret pattern
  82         as a regex).
  83
  84 -n::
  85         Prefix the line number to matching lines.
  86
  87 -l::
  88 --files-with-matches::
  89 --name-only::
  90 -L::
  91 --files-without-match::
  92         Instead of showing every matched line, show only the
  93         names of files that contain (or do not contain) matches.
  94         For better compatibility with git-diff, --name-only is a
  95         synonym for --files-with-matches.
  96
  97 -c::
  98 --count::
  99         Instead of showing every matched line, show the number of
 100         lines that match.
 101
 102 -[ABC] <context>::
 103         Show `context` trailing (`A` -- after), or leading (`B`
 104         -- before), or both (`C` -- context) lines, and place a
 105         line containing `--` between contiguous groups of
 106         matches.
 107
 108 -<num>::
 109         A shortcut for specifying -C<num>.
 110
 111 -f <file>::
 112         Read patterns from <file>, one per line.
 113
 114 -e::
 115         The next parameter is the pattern. This option has to be
 116         used for patterns starting with - and should be used in
 117         scripts passing user input to grep.  Multiple patterns are
 118         combined by 'or'.
 119
 120 --and::
 121 --or::
 122 --not::
 123 ( ... )::
 124         Specify how multiple patterns are combined using Boolean
 125         expressions.  `--or` is the default operator.  `--and` has
 126         higher precedence than `--or`.  `-e` has to be used for all
 127         patterns.
 128
 129 --all-match::
 130         When giving multiple pattern expressions combined with `--or`,
 131         this flag is specified to limit the match to files that
 132         have lines to match all of them.
 133
 134 `<tree>...`::
 135         Search blobs in the trees for specified patterns.
 136
 137 \--::
 138         Signals the end of options; the rest of the parameters
 139         are <path> limiters.
 140
 141
 142 Example
 143 -------
 144
 145 git grep -e \'#define\' --and \( -e MAX_PATH -e PATH_MAX \)::
 146         Looks for a line that has `#define` and either `MAX_PATH` or
 147         `PATH_MAX`.
 148
 149 git grep --all-match -e NODE -e Unexpected::
 150         Looks for a line that has `NODE` or `Unexpected` in
 151         files that have lines that match both.
