<h1> The s6-svstat program </h1>
<p>
s6-svstat prints a short, human-readable summary of the state of a process
monitored by <a href="s6-supervise.html">s6-supervise</a>.
</p>
<h2> Interface </h2>
<pre>
s6-svstat [ -n ] <em>servicedir</em>
</pre>
<p>
s6-svstat gives information about the process being monitored
at the <em>servicedir</em> <a href="servicedir.html">service directory</a>, then
exits 0. The information includes the following:
</p>
<ul>
<li> whether the process is up or down </li>
<li> the process' pid, if it is up, or its last exit code or terminating
signal, if it is down </li>
<li> what its default state is, if it is different from its current state </li>
<li> the number of seconds since it last changed states </li>
<li> if the current state is transient and will change as soon as the
kernel's scheduler picks up s6-supervise </li>
</ul>
<h2> Options </h2>
<ul>
<li> <tt>-n</tt> : if the monitored process has been killed by a signal,
print the signal number. By default, a symbolic name for the signal will be
printed instead. </li>
</ul>
