<h2 id="_description">DESCRIPTION</h2>
<div class="sectionbody">
<div class="paragraph">
<p>For every pathname, this command will list if each attribute is <em>unspecified</em>,

<div class="sectionbody">
<div class="dlist">
<dl>
<dt class="hdlist1">-a</dt>
<dt class="hdlist1">--all</dt>
<dd>
<p>List all attributes that are associated with the specified
paths.  If this option is used, then <em>unspecified</em> attributes
will not be included in the output.</p>
</dd>
<dt class="hdlist1">--cached</dt>
<dd>
<p>Consider .<code>gitattributes</code> in the index only, ignoring the working tree.</p>
</dd>
<dt class="hdlist1">--stdin</dt>
<dd>
<p>Read pathnames from the standard input, one per line,
instead of from the command line.</p>
</dd>
<dt class="hdlist1">-z</dt>
<dd>
<p>The output format is modified to be machine-parsable.
If <code>--stdin</code> is also given, input paths are separated
with a NUL character instead of a linefeed character.</p>
</dd>
<dt class="hdlist1">--source=&lt;tree-ish&gt;</dt>
<dd>
<p>Check attributes against the specified tree-ish. It is common to
specify the source tree by naming a commit, branch, or tag associated
with it.</p>
</dd>
<dt class="hdlist1">--</dt>
<dd>
<p>Interpret all preceding arguments as attributes and all following
arguments as path names.</p>
</dd>
</dl>
</div>
<div class="paragraph">
<p>If none of <code>--stdin</code>, <code>--all</code>, or <code>--</code> is used, the first argument
will be treated as an attribute and the rest of the arguments as
pathnames.</p>
</div>
</div>
</div>
<div class="sect1">
<h2 id="_output">OUTPUT</h2>
<div class="sectionbody">
<div class="paragraph">
<p>The output is of the form:
&lt;path&gt; COLON SP &lt;attribute&gt; COLON SP &lt;info&gt; LF</p>
</div>
<div class="paragraph">
<p>unless <code>-z</code> is in effect, in which case NUL is used as delimiter:
&lt;path&gt; NUL &lt;attribute&gt; NUL &lt;info&gt; NUL</p>
</div>
<div class="paragraph">
<p>&lt;path&gt; is the path of a file being queried, &lt;attribute&gt; is an attribute
being queried, and &lt;info&gt; can be either:</p>
</div>
<div class="dlist">
<dl>
<dt class="hdlist1"><em>unspecified</em></dt>
<dd>
<p>when the attribute is not defined for the path.</p>
</dd>
<dt class="hdlist1"><em>unset</em></dt>
<dd>
<p>when the attribute is defined as false.</p>
</dd>
<dt class="hdlist1"><em>set</em></dt>
<dd>
<p>when the attribute is defined as true.</p>
</dd>
<dt class="hdlist1">&lt;value&gt;</dt>
<dd>
<p>when a value has been assigned to the attribute.</p>

<div class="paragraph">
<p>Buffering happens as documented under the <code>GIT_FLUSH</code> option in
