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
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.

--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
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. The pager argument is optional; if
specified, it 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.

-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 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.
