 DESCRIPTION
 -----------
-Searches list of files `git-ls-files` produces for lines
-containing a match to the given pattern.
+Look for specified patterns in the working tree files, blobs
+registered in the index file, or given tree objects.
 
 
 OPTIONS
 -------
-`--`::
-	Signals the end of options; the rest of the parameters
-	are <path> limiters.
+--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.
+
+-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.
 
-<option>...::
-	Either an option to pass to `grep` or `git-ls-files`.
+-c | --count::
+	Instead of showing every matched line, show the number of
+	lines that match.
 
-	The following are the specific `git-ls-files` options
-	that may be given: `-o`, `--cached`, `--deleted`, `--others`,
-	`--killed`, `--ignored`, `--modified`, `--exclude=*`,
-	`--exclude-from=*`, and `--exclude-per-directory=*`.
+-[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.
 
-	All other options will be passed to `grep`.
+-f <file>::
+	Read patterns from <file>, one per line.
 
-<pattern>::
-	The pattern to look for.  The first non option is taken
-	as the pattern; if your pattern begins with a dash, use
-	`-e <pattern>`.
+-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'.
 
-<path>...::
-	Optional paths to limit the set of files to be searched;
-	passed to `git-ls-files`.
+--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.
 
+`<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`.
