<div class="paragraph"><p>Look for specified patterns in the tracked files in the work tree, blobs
registered in the index file, or blobs in given tree objects.</p></div>
</div>
<h2 id="_options">OPTIONS</h2>
<div class="sectionbody">
<div class="dlist"><dl>
<dt class="hdlist1">
--cached
</dt>
<dd>
<p>
Instead of searching tracked files in the working tree, search
blobs registered in the index file.
</p>
</dd>
<dt class="hdlist1">
--no-index
</dt>
<dd>
<p>
Search files in the current directory, not just those tracked by git.
</p>
</dd>
<dt class="hdlist1">
-a
</dt>
<dt class="hdlist1">
--text
</dt>
<dd>
<p>
Process binary files as if they were text.
</p>
</dd>
<dt class="hdlist1">
-i
</dt>
<dt class="hdlist1">
--ignore-case
</dt>
<dd>
<p>
Ignore case differences between the patterns and the
files.
</p>
</dd>
<dt class="hdlist1">
-I
</dt>
<dd>
<p>
Don’t match the pattern in binary files.
</p>
</dd>
<dt class="hdlist1">
--max-depth <depth>
</dt>
<dd>
<p>
For each <pathspec> given on command line, descend at most <depth>
levels of directories. A negative value means no limit.
</p>
</dd>
<dt class="hdlist1">
-w
</dt>
<dt class="hdlist1">
--word-regexp
</dt>
<dd>
<p>
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).
</p>
</dd>
<dt class="hdlist1">
-v
</dt>
<dt class="hdlist1">
--invert-match
</dt>
<dd>
<p>
Select non-matching lines.
</p>
</dd>
<dt class="hdlist1">
-h
</dt>
<dt class="hdlist1">
-H
</dt>
<dd>
<p>
By default, the command shows the filename for each
match. <tt>-h</tt> option is used to suppress this output.
<tt>-H</tt> is there for completeness and does not do anything
except it overrides <tt>-h</tt> given earlier on the command
line.
</p>
</dd>
<dt class="hdlist1">
--full-name
</dt>
<dd>
<p>
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.
</p>
</dd>
<dt class="hdlist1">
-E
</dt>
<dt class="hdlist1">
--extended-regexp
</dt>
<dt class="hdlist1">
-G
</dt>
<dt class="hdlist1">
--basic-regexp
</dt>
<dd>
<p>
Use POSIX extended/basic regexp for patterns. Default
is to use basic regexp.
</p>
</dd>
<dt class="hdlist1">
-F
</dt>
<dt class="hdlist1">
--fixed-strings
</dt>
<dd>
<p>
Use fixed strings for patterns (don’t interpret pattern
as a regex).
</p>
</dd>
<dt class="hdlist1">
-n
</dt>
<dd>
<p>
Prefix the line number to matching lines.
</p>
</dd>
<dt class="hdlist1">
-l
</dt>
<dt class="hdlist1">
--files-with-matches
</dt>
<dt class="hdlist1">
--name-only
</dt>
<dt class="hdlist1">
-L
</dt>
<dt class="hdlist1">
--files-without-match
</dt>
<dd>
<p>
Instead of showing every matched line, show only the
names of files that contain (or do not contain) matches.
For better compatibility with <em>git diff</em>, <tt>--name-only</tt> is a
synonym for <tt>--files-with-matches</tt>.
</p>
</dd>
<dt class="hdlist1">
-z
</dt>
<dt class="hdlist1">
--null
</dt>
<dd>
<p>
Output \0 instead of the character that normally follows a
file name.
</p>
</dd>
<dt class="hdlist1">
-c
</dt>
<dt class="hdlist1">
--count
</dt>
<dd>
<p>
Instead of showing every matched line, show the number of
lines that match.
</p>
</dd>
<dt class="hdlist1">
--color[=<when>]
</dt>
<dd>
<p>
Show colored matches.
The value must be always (the default), never, or auto.
</p>
</dd>
<dt class="hdlist1">
--no-color
</dt>
<dd>
<p>
Turn off match highlighting, even when the configuration file
gives the default to color output.
Same as <tt>--color=never</tt>.
</p>
</dd>
<dt class="hdlist1">
-[ABC] <context>
</dt>
<dd>
<p>
Show <tt>context</tt> trailing (<tt>A</tt> — after), or leading (<tt>B</tt>
 — before), or both (<tt>C</tt> — context) lines, and place a
line containing <tt>--</tt> between contiguous groups of
matches.
</p>
</dd>
<dt class="hdlist1">
-<num>
</dt>
<dd>
<p>
A shortcut for specifying <tt>-C<num></tt>.
</p>
</dd>
<dt class="hdlist1">
-p
</dt>
<dt class="hdlist1">
--show-function
</dt>
<dd>
<p>
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 <em>git diff</em> works out
patch hunk headers (see <em>Defining a custom hunk-header</em> in
<a href="gitattributes.html">gitattributes(5)</a>).
</p>
</dd>
<dt class="hdlist1">
-f <file>
</dt>
<dd>
<p>
Read patterns from <file>, one per line.
</p>
</dd>
<dt class="hdlist1">
-e
</dt>
<dd>
<p>
The next parameter is the pattern. This option has to be
used for patterns starting with <tt>-</tt> and should be used in
scripts passing user input to grep. Multiple patterns are
combined by <em>or</em>.
</p>
</dd>
<dt class="hdlist1">
--and
</dt>
<dt class="hdlist1">
--or
</dt>
<dt class="hdlist1">
--not
</dt>
<dt class="hdlist1">
( … )
</dt>
<dd>
<p>
Specify how multiple patterns are combined using Boolean
expressions. <tt>--or</tt> is the default operator. <tt>--and</tt> has
higher precedence than <tt>--or</tt>. <tt>-e</tt> has to be used for all
patterns.
</p>
</dd>
<dt class="hdlist1">
--all-match
</dt>
<dd>
<p>
When giving multiple pattern expressions combined with <tt>--or</tt>,
this flag is specified to limit the match to files that
have lines to match all of them.
</p>
</dd>
<dt class="hdlist1">
-q
</dt>
<dt class="hdlist1">
--quiet
</dt>
<dd>
<p>
Do not output matched lines; instead, exit with status 0 when
there is a match and with non-zero status when there isn’t.
</p>
</dd>
<dt class="hdlist1">
<tree>…
</dt>
<dd>
<p>
Instead of searching tracked files in the working tree, search
blobs in the given trees.
</p>
</dd>
<dt class="hdlist1">
--
</dt>
<dd>
<p>
Signals the end of options; the rest of the parameters
are <pathspec> limiters.
</p>
</dd>
<dt class="hdlist1">
<pathspec>…
</dt>
<dd>
<p>
If given, limit the search to paths matching at least one pattern.
Both leading paths match and glob(7) patterns are supported.
</p>
</dd>
