<h1> The <tt>s6-chown</tt> program </h1>
<p>
s6-chown changes the owner and/or group of a file.
</p>
<h2> Interface </h2>
<pre>
s6-chown [ -U ] [ -u uid ] [ -g gid ] file
</pre>
<ul>
<li> s6-chown changes <em>file</em>'s owner to (numeric) <em>uid</em> and group
to (numeric) <em>gid</em>. </li>
<li> If <em>uid</em> isn't provided, the owner remains the same; if <em>gid</em>
isn't provided, the group remains the same. </li>
<li> The <tt>-U</tt> option sets <em>uid</em> to the value of the UID
environment variable and <em>gid</em> to the value of the GID environment variable.
This makes s6-chown easily usable with
<a href="http://www.skarnet.org/software/s6/s6-envuidgid.html">s6-envuidgid</a>:
<tt> s6-envuidgid account s6-chown -U file </tt> changes <em>file</em>'s uid and
gid to <em>account</em>'s. </li>
</ul>
<h2> Posixness </h2>
<p>
s6-chown <strong>is not</strong> suitable as a Single Unix
<a href="http://pubs.opengroup.org/onlinepubs/9699919799/utilities/chown.html">chown</a>
program.
