Coloring matches makes them easier to spot in the output. Add two options and two parameters: color.grep (to turn coloring on or off), color.grep.match (to set the color of matches), --color and --no-color (to turn coloring on or off, respectively). The output of external greps is not changed. This patch is based on earlier ones by Nguyễn Thái Ngọc Duy and Thiago Alves.

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::
|
|
--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::
|
|
Show colored matches.
|
|
|
|
--no-color::
|
|
Turn off match highlighting, even when the configuration file
|
|
gives the default to color output.
|
|
|
|
-[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.
