<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><fileset></code>, <code><dirset></code> and
<code><filelist></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><attrib file="${dist}/run.bat" readonly="true" hidden="true"/></pre>
</blockquote>
<p>makes the "run.bat" file read-only and hidden.</p>
<blockquote>
<pre><attrib readonly="false">
<fileset dir="${meta.inf}" includes="**/*.xml"/>
<attrib>
</pre>
</blockquote>
<p>makes all ".xml" files below <code>${meta.inf}</code> readable.</p>
<blockquote>
<pre>
<attrib readonly="true" archive="true">
<fileset dir="shared/sources1">
<exclude name="**/trial/**"/>
</fileset>
<fileset refid="other.shared.sources"/>
</attrib>
</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>
