<h1> The s6-rc-oneshot-run internal program </h1>
<p>
s6-rc-oneshot-run executes a oneshot service's <tt>up</tt> or
<tt>down</tt> script taken from the current live compiled database.
</p>
<p>
s6-rc-oneshot-run is not meant to be used directly; it is used
in internal scripts created by
<a href="s6-rc-compile.html">s6-rc-compile</a>, which are invoked during an
<a href="s6-rc.html">s6-rc</a> execution.
</p>
<h2> Interface </h2>
<pre>
s6-rc-oneshot-run [ -l <em>live</em> ] [ -b ] up|down <em>n</em>
</pre>
<ul>
<li> s6-rc-oneshot-run executes into the <tt>up</tt> or <tt>down</tt> script
of the <em>n</em>th oneshot service defined
in the current compiled service database (i.e. the compiled linked from the
live directory). </li>
</ul>
<h2> Options </h2>
<ul>
<li> <tt>-l <em>live</em></tt> : use the live directory in
<em>live</em>. Default is <tt>/run/s6-rc</tt>, or what was given to the
<tt>--livedir</tt> configure option at compile time. </li>
<li> <tt>-b</tt> : blocking lock. If the service database is currently
being used by another program, s6-rc-oneshot-run will wait until that
other program has released its lock on the database, then proceed.
By default, s6-rc-oneshot-run fails with an error message if the database
is currently in use. </li>
</ul>
<h2> Exit codes </h2>
<ul>
<li> 3: invalid service number </li>
<li> 4: invalid service database </li>
<li> 100: wrong usage </li>
<li> 111: system call failed </li>
<li> other exit codes: returned from the executed <tt>up</tt> or <tt>down</tt> script </li>
</ul>
