                  [ [--[no-]exclude-standard] [--cached | --no-index | --untracked] | <tree>...]
                  [--] [<pathspec>...]


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.

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
           In addition to searching in the tracked files in the working tree, search also in untracked
           files.

       --no-exclude-standard
           Also search in ignored files by not honoring the .gitignore mechanism. Only useful with
           --untracked.

       --exclude-standard
           Do not pay attention to ignored files specified via the .gitignore mechanism. Only useful when
           searching files in the current directory with --no-index.

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

       -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
           Prefix the line number to matching lines.

       -l, --files-with-matches, --name-only, -L, --files-without-match
           Instead of showing every matched line, show only the names of files that contain (or do not
           contain) matches. For better compatibility with git diff, --name-only is a synonym for
           --files-with-matches.

       -O [<pager>], --open-files-in-pager [<pager>]
           Open the matching files in the pager (not the output of grep). If the pager happens to be "less"
           or "vi", and the user specified only one pattern, the first file is positioned at the first match
           automatically.

       -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.

       -e
           The next parameter is the pattern. This option has to be used for patterns starting with - and
           should be used in scripts passing user input to grep. Multiple patterns are combined by or.

       --and, --or, --not, ( ... )
           Specify how multiple patterns are combined using Boolean expressions.  --or is the default
           operator.  --and has higher precedence than --or.  -e has to be used for all patterns.

       --all-match
           When giving multiple pattern expressions combined with --or, this 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 -Signals
           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.
