git-grep(1)
===========
NAME
----
git-grep - Print lines matching a pattern
SYNOPSIS
--------
[verse]
'git-grep' [--cached]
[-a | --text] [-I] [-i | --ignore-case] [-w | --word-regexp]
[-v | --invert-match] [-h|-H] [--full-name]
[-E | --extended-regexp] [-G | --basic-regexp] [-F | --fixed-strings]
[-n] [-l | --files-with-matches] [-L | --files-without-match]
[-c | --count] [--all-match]
[-A <post-context>] [-B <pre-context>] [-C <context>]
[-f <file>] [-e] <pattern> [--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.
-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.
-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.
-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.
