<h2><a name='sect0'>Name</a></h2>
svwaitdown - waits for services controlled by <i>runsv(8)</i> to be down
<h2><a name='sect1'>Synopsis</a></h2>
<b>svwaitdown</b>
[ <b>-v</b> ] [ <b>-k</b> ] [ <b>-t</b> <i>sec</i> ] <i>services</i>
<h2><a name='sect2'>Description</a></h2>
<i>services</i> consists of one or more
arguments, each argument naming a service directory. <p>
<b>svwaitdown</b> sends each
<i>service</i> given at the command line the ‘‘down’’ command, and waits for it to
become down. The <i>services</i> given at the command line must be controlled by
<i><b>runsv</b>(8)</i>. <p>
<b>svwaitdown</b> blocks, limited by a <i>timeout</i>, until all <i>services</i> are
down or reports errors.
<h2><a name='sect3'>Options</a></h2>
<dl>
<dt><b>-v</b> </dt>
<dd>verbose. Print verbose messages to stderr.
</dd>
<dt><b>-t <i>sec</b> </i></dt>
<dd>Set the timeout for waiting for <i>services</i> to become down to <i>sec</i> seconds.
<i>sec</i> must be between 1 and 6000. Default is 600 (10 minutes). </dd>
<dt><b>-k</b> </dt>
<dd>Kill. If the
timeout is reached before all <i>services</i> are down, tell the <i><b>runsv</b>(8)</i> processes
to send the <i>services</i> a KILL signal. </dd>
<dt><b>-x</b> </dt>
<dd>Exit. Send each <i>service</i> the ‘‘exit’’ command
additionally to the ‘‘down’’ command, and wait for the corresponding <i><b>runsv</b>(8)</i>
processes to exit instead for the <i>services</i> to be down. </dd>
</dl>
<h2><a name='sect4'>Exit Codes</a></h2>
<b>svwaitdown</b>
returns 0 as soon as all <i>services</i> are down. <p>
If a <i>service</i> is usually controlled
by <i><b>runsv (8)</i>,</b> but no supervisor process is currently running in the directory,
<b>svwaitdown</b> treats this <i>service</i> as if it would be down. <p>
For each <i>service</i>
that causes an error while checking, <b>svwaitdown</b> increases the exit code
by one and exits non zero. The maximum is 100. <p>
<b>svwaitdown</b> returns 111 on
error, or if the timeout <i>sec</i> was reached.
