DESCRIPTION
       Look for specified patterns in the tracked files in the work tree,
       blobs registered in the index file, or blobs in given tree objects.
       Patterns are lists of one or more search expressions separated by
       newline characters. An empty string as search expression matches all
       lines.

CONFIGURATION
       grep.lineNumber
           If set to true, enable -n option by default.

       grep.patternType
           Set the default matching behavior. Using a value of basic,
           extended, fixed, or perl will enable the --basic-regexp,
           --extended-regexp, --fixed-strings, or --perl-regexp option
           accordingly, while the value default will return to the default
           matching behavior.

       grep.extendedRegexp
           If set to true, enable --extended-regexp option by default. This
           option is ignored when the grep.patternType option is set to a
           value other than default.

       grep.fullName
           If set to true, enable --full-name option by default.

OPTIONS
       --cached
           Instead of searching tracked files in the working tree, search
           blobs registered in the index file.

       --no-index
           Search files in the current directory that is not managed by Git.

       --untracked
       -a, --text
           Process binary files as if they were text.

       --textconv
           Honor textconv filter settings.

       --no-textconv
           Do not honor textconv filter settings. This is the default.

       -i, --ignore-case
           Ignore case differences between the patterns and the files.

       -I
           Don't match the pattern in binary files.

       --max-depth <depth>
           For each <pathspec> given on command line, descend at most <depth>
           levels of directories. A negative value means no limit. This option
           is ignored if <pathspec> contains active wildcards. In other words
           if "a*" matches a directory named "a*", "*" is matched literally so
           --max-depth is still effective.

       -w, --word-regexp
           Match the pattern only at word boundary (either begin at the
           beginning of a line, or preceded by a non-word character; end at
           the end of a line or followed by a non-word character).

       -v, --invert-match
           Select non-matching lines.

       -h, -H
           By default, the command shows the filename for each match.  -h
           option is used to suppress this output.  -H is there for
           completeness and does not do anything except it overrides -h given
           earlier on the command line.

       --full-name
           When run from a subdirectory, the command usually outputs paths
           relative to the current directory. This option forces paths to be
           output relative to the project top directory.

       -E, --extended-regexp, -G, --basic-regexp
           Use POSIX extended/basic regexp for patterns. Default is to use
           basic regexp.

       -P, --perl-regexp
           Use Perl-compatible regexp for patterns. Requires libpcre to be
           compiled in.

       -F, --fixed-strings
           Use fixed strings for patterns (don't interpret pattern as a
           regex).

       -n, --line-number
           must be stuck to the option without a space. If pager is
           unspecified, the default pager will be used (see core.pager in git-
           config(1)).

       -z, --null
           Output \0 instead of the character that normally follows a file
           name.

       -c, --count
           Instead of showing every matched line, show the number of lines
           that match.

       --color[=<when>]
           Show colored matches. The value must be always (the default),
           never, or auto.

       --no-color
           Turn off match highlighting, even when the configuration file gives
           the default to color output. Same as --color=never.

       --break
           Print an empty line between matches from different files.

       --heading
           Show the filename above the matches in that file instead of at the
           start of each shown line.

       -p, --show-function
           Show the preceding line that contains the function name of the
           match, unless the matching line is a function name itself. The name
           is determined in the same way as git diff works out patch hunk
           headers (see Defining a custom hunk-header in gitattributes(5)).

       -<num>, -C <num>, --context <num>
           Show <num> leading and trailing lines, and place a line containing
           -- between contiguous groups of matches.

       -A <num>, --after-context <num>
           Show <num> trailing lines, and place a line containing -- between
           contiguous groups of matches.

       -B <num>, --before-context <num>
           Show <num> leading lines, and place a line containing -- between
           contiguous groups of matches.

       -W, --function-context
           Show the surrounding text from the previous line containing a
           function name up to the one before the next function name,
           effectively showing the whole function in which the match was
           found.

       -f <file>
           Read patterns from <file>, one per line.

           flag is specified to limit the match to files that have lines to
           match all of them.

       -q, --quiet
           Do not output matched lines; instead, exit with status 0 when there
           is a match and with non-zero status when there isn't.

       <tree>...
           Instead of searching tracked files in the working tree, search
           blobs in the given trees.

       --
           Signals the end of options; the rest of the parameters are
           <pathspec> limiters.

       <pathspec>...
           If given, limit the search to paths matching at least one pattern.
           Both leading paths match and glob(7) patterns are supported.

EXAMPLES
       git grep 'time_t' -- '*.[ch]'
           Looks for time_t in all tracked .c and .h files in the working
           directory and its subdirectories.

       git grep -e '#define' --and \( -e MAX_PATH -e PATH_MAX \)
           Looks for a line that has #define and either MAX_PATH or PATH_MAX.

       git grep --all-match -e NODE -e Unexpected
           Looks for a line that has NODE or Unexpected in files that have
           lines that match both.
