<h1>The system-shutdown program</h1>
<p>
system-shutdown is the interface to the
<a href="//0x53.net/software/goetia/goetia-base/bin/system-shutdown-daemon.html">system-shutdown-daemon</a>.
</p>
<h2>Interface</h2>
<pre> system-shutdown -h | -p | -r</pre>
<ul>
<li>
system-shutdown writes its argument to the file <code>DIRECTIVE</code> in the envdir at the
<code>shutdown-directive</code> subdirectory of the
<a href="//0x53.net/software/goetia/rundir.html#system">system runtime directory</a>.
</li>
<li>
It continues to initiate the shutdown sequence by starting the service
<a href="//0x53.net/software/goetia/goetia-linux-init/service/system/goetia-shutdown.html">goetia-shutdown</a>.
</li>
</ul>
<h2>Options</h2>
<ul>
<li>
<code>-h</code>: at the end of the shutdown sequence, halt the system.
</li>
<li>
<code>-p</code>: at the end of the shutdown sequence, poweroff the system.
</li>
<li>
<code>-r</code>: at the end of the shutdown sequence, reboot the system.
</li>
</ul>
<h2>Exit codes</h2>
<ul>
<li>
system-shutdown exits 100 if wrong options were used.
</li>
<li>
Since system-shutdown is an
<a href="https://skarnet.org/software/execline/">execline</a>
script, it exits with an approximation
of employed program that failed.
</li>
<li>
system-shutdown mostly uses
<a href="https://skarnet.org/software/execline/">execline</a>
and
<a href="https://skarnet.org/software/s6/">s6</a>
software, the exit behaviour of which can be looked up on
their respective pages.
</li>
<li>
See also:
<a href="https://skarnet.org/software/execline/exitcodes.html">execline exit code handling</a>.
</li>
</ul>
<h2>Notes</h2>
<p>
There is a reason this program exists as part of (multiple)
goetia-init packages and not as part of
<a href="//0x53.net/software/goetia/goetia-base">goetia-base</a>.
It is that some supported init systems, like
<a href="https://skarnet.org/software/s6-linux-init/">s6-linux-init</a>
(through <a href="//0x53.net/software/goetia/goetia-s6-linux-init">goetia-s6-linux-init</a>)
provide their own shutdown procedure and interface.
