<h3>Examples</h3>
<blockquote>
  <p><code>&lt;chown file=&quot;${dist}/start.sh&quot; owner=&quot;coderjoe&quot;/&gt;</code></p>
</blockquote>
<p>makes the &quot;start.sh&quot; file belong to coderjoe on a
UNIX system.</p>
<blockquote>
<pre>
    &lt;chown owner=&quot;coderjoe&quot;&gt;
      &lt;fileset dir=&quot;${dist}/bin&quot; includes=&quot;**/*.sh&quot;/&gt;
    &lt;/chown&gt;
</pre>
</blockquote>
<p>makes all &quot;.sh&quot; files below <code>${dist}/bin</code>
belong to coderjoe on a UNIX system.</p>
<blockquote>
<pre>
&lt;chown owner=&quot;coderjoe&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;/chown&gt;
</pre>
</blockquote>
<p>makes all files below <code>shared/sources1</code> (except those
below any directory named trial) belong to coderjoe on a UNIX 
system. In addition all files belonging to a FileSet
with <code>id</code> <code>other.shared.sources</code> get the same
owner.</p>

<blockquote>
<pre>
&lt;chown owner=&quot;webadmin&quot; type=&quot;file&quot;&gt;
  &lt;fileset dir=&quot;/web&quot;&gt;
    &lt;include name=&quot;**/*.cgi&quot;/&gt;
    &lt;include name=&quot;**/*.old&quot;/&gt;
  &lt;/fileset&gt;
  &lt;dirset dir=&quot;/web&quot;&gt;
    &lt;include name=&quot;**/private_*&quot;/&gt;
  &lt;/dirset&gt;
&lt;/chmod&gt;
</pre>
</blockquote>

<p>makes cgi scripts, files with a <code>.old</code> extension or
directories beginning with <code>private_</code> belong to the user named
webadmin. A directory ending in <code>.old</code> or a file beginning with 
<code>private_</code> would remain unaffected.</p>
