           [-v | --invert-match] [-h|-H] [--full-name]

           [-A <post-context>] [-B <pre-context>] [-C <context>]

           [--and|--or|--not|(|)|-e <pattern>...] [<tree>...]

           [--] [<path>...]

DESCRIPTION

Look for specified patterns in the working tree files, blobs registered in the index file, or given tree objects.

OPTIONS

--cached

Instead of searching in the working tree files, check the blobs registered in the index file.

-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.

-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.

-F | --fixed-strings

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

-n

Prefix the line number to matching lines.

-l | --files-with-matches | -L | --files-without-match

Instead of showing every matched line, show only the names of files that contain (or do not contain) matches.

-c | --count

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

-[ABC] <context>

Show context trailing (A --- after), or leading (B --- before), or both (C --- context) lines, and place a line containing -- between contiguous groups of matches.

-<num>

A shortcut for specifying -C<num>.

-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.

<tree>...

Search blobs in the trees for specified patterns.

--

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

EXAMPLE

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.
