DESCRIPTION
-----------
-Look for specified patterns in the working tree files, blobs
-registered in the index file, or given tree objects.
+Look for specified patterns in the tracked files in the work tree, blobs
+registered in the index file, or blobs in given tree objects.
+
+
+CONFIGURATION
+-------------
+
+grep.lineNumber::
+ If set to true, enable '-n' option by default.
+
+grep.extendedRegexp::
+ If set to true, enable '--extended-regexp' option by default.
OPTIONS
-------
--cached::
- Instead of searching in the working tree files, check
- the blobs registered in the index file.
+ 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::
Don't match the pattern in binary files.
--max-depth <depth>::
- For each pathspec given on command line, descend at most <depth>
+ For each <pathspec> given on command line, descend at most <depth>
levels of directories. A negative value means no limit.
-w::
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-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.
+ 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.
-z::
--null::
Instead of showing every matched line, show the number of
lines that match.
---color::
+--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`
matches.
-<num>::
- A shortcut for specifying -C<num>.
+ A shortcut for specifying `-C<num>`.
-p::
--show-function::
-e::
The next parameter is the pattern. This option has to be
- used for patterns starting with - and should be used in
+ used for patterns starting with `-` and should be used in
scripts passing user input to grep. Multiple patterns are
combined by 'or'.
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>...`::
- Search blobs in the trees for specified patterns.
+<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 <path> limiters.
+ 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.
-Example
--------
+Examples
+--------
+
+git grep {apostrophe}time_t{apostrophe} \-- {apostrophe}*.[ch]{apostrophe}::
+ Looks for `time_t` in all tracked .c and .h files in the working
+ directory and its subdirectories.
-git grep -e \'#define\' --and \( -e MAX_PATH -e PATH_MAX \)::
+git grep -e {apostrophe}#define{apostrophe} --and \( -e MAX_PATH -e PATH_MAX \)::
Looks for a line that has `#define` and either `MAX_PATH` or
`PATH_MAX`.
Looks for a line that has `NODE` or `Unexpected` in
files that have lines that match both.
