</pre>
<ul>
<li> s6-ipcclient connects to a Unix domain socket on <em>path</em>. </li>
<li> It executes into <em>prog...</em> with descriptor 6 reading from
the socket and descriptor 7 writing to it. </li>
</ul>
<h2> Environment variables </h2>
<p>
<em>prog...</em> is run with
the following variables set:
</p>
<ul>
