<h2><a name="attrib">Attrib</a></h2>
<p><em>Since Ant 1.6.</em></p>
<h3>Description</h3>

<p>Changes the attributes of a file or all files inside specified
directories.  Right now it has effect only under Windows. Each of the
4 possible permissions has its own attribute, matching the arguments
for the attrib command.</p>

<p><a href="../CoreTypes/fileset.html">FileSet</a>s, 
<a href="../CoreTypes/dirset.html">DirSet</a>s or <a
href="../CoreTypes/filelist.html">FileList</a>s can be specified using
nested <code>&lt;fileset&gt;</code>, <code>&lt;dirset&gt;</code> and 
<code>&lt;filelist&gt;</code> elements.</p>

<p>Starting with Ant 1.7, this task supports arbitrary <a
href="../CoreTypes/resources.html#collection">Resource Collection</a>s
as nested elements.</p>

<p>By default this task will use a single invocation of the underlying
attrib command.  If you are working on a large number of files this
may result in a command line that is too long for your operating
system.  If you encounter such problems, you should set the
maxparallel attribute of this task to a non-zero value.  The number to
use highly depends on the length of your file names (the depth of your
directory tree), so you'll have to experiment a little.</p>

<h3>Examples</h3>
  <blockquote>
<pre>&lt;attrib file=&quot;${dist}/run.bat&quot; readonly=&quot;true&quot; hidden=&quot;true&quot;/&gt;</pre>
</blockquote>
<p>makes the &quot;run.bat&quot; file read-only and hidden.</p>
<blockquote>
  <pre>&lt;attrib readonly=&quot;false&quot;&gt;
  &lt;fileset dir=&quot;${meta.inf}&quot; includes=&quot;**/*.xml&quot;/&gt;
&lt;attrib&gt;
</pre>
</blockquote>
<p>makes all &quot;.xml&quot; files below <code>${meta.inf}</code> readable.</p>
<blockquote>
  <pre>
&lt;attrib readonly=&quot;true&quot; archive=&quot;true&quot;&gt;
  &lt;fileset dir=&quot;shared/sources1&quot;&gt;
    &lt;exclude name=&quot;**/trial/**&quot;/&gt;
  &lt;/fileset&gt;
  &lt;fileset refid=&quot;other.shared.sources&quot;/&gt;
&lt;/attrib&gt;
</pre>
</blockquote>
<p>makes all files below <code>shared/sources1</code> (except those below any
  directory named trial) read-only and archived. In addition all files belonging
  to a FileSet with <code>id</code> <code>other.shared.sources</code> get the
  same attributes.</p>
