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.
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, not just those tracked by
git.
-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.
-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, --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.
-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.
-[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>.
-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)).
-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.
