<h1> The <tt>s6-frontend-alias-sv</tt> program </h1>
<p>
<tt>s6-frontend-alias-sv</tt> implements
<a href="http://smarden.org/runit/">runit</a>'s
<a href="http://smarden.org/runit/sv.8.html">sv</a> command over a
<a href="//skarnet.org/software/s6/">s6</a> supervision tree, via
native <a href="//skarnet.org/software/s6/">s6</a> commands.
</p>
<h2> Interface </h2>
<pre>
s6-frontend-alias-sv [ -v ] [ -w <em>secs</em> ] <em>command</em> <em>services...</em>
</pre>
<p>
When s6-frontend has been configured with the
<tt>--enable-aliases-runit</tt> option, the
<tt>s6-frontend-alias-sv</tt> program is built, and at installation
time, a <tt>sv</tt> symbolic link is created, pointing to it.
</p>
<p>
<tt>s6-frontend-alias-sv</tt> implements most of the functionality of
<a href="http://smarden.org/runit/sv.8.html">sv</a>, as closely as
possible. When some functionality cannot be emulated on a s6
supervision tree, it prints an error message to stderr and exits 100.
</p>
<h2> Notes </h2>
<ul>
<li> <tt>s6-frontend-alias-sv</tt> is a convenience program, written
so that runit users can keep using <tt>sv</tt> to control their
s6 services. However, it is not an "official" interface, because there
are a few fundamental differences between the conception of runit and
the conception of s6 that make <tt>sv</tt> a poor fit to accurately
interface with the advanced features of s6. It is recommended that
<tt>sv</tt> users become familiar with idiomatic s6 commands such as
<a href="//skarnet.org/software/s6/s6-svc.html">s6-svc</a>,
<a href="//skarnet.org/software/s6/s6-svstat.html">s6-svstat</a>, and
<a href="//skarnet.org/software/s6/s6-svwait.html">s6-svwait</a>. </li>
</ul>
