<h2><a name='sect0'>Name</a></h2>
svwaitup - waits for services controlled by <i>runsv(8)</i> to be up
<h2><a name='sect1'>Synopsis</a></h2>
<b>svwaitup</b>
[ <b>-v</b> ] [ <b>-s</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>svwaitup</b> checks each <i>service</i> given
at the command line for being at least the specified number of seconds
<i>sec</i> up. The <i>services</i> given at the command line must be controlled by <i><b>runsv</b>(8)</i>.
<p>
<b>svwaitup</b> blocks until all <i>services</i> were up and running at least <i>sec</i> seconds
when <b>svwaitup</b> was checking 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>-s <i>sec</b> </i></dt>
<dd>Set the minimum number of seconds each <i>service</i>
has to be up to <i>sec</i> seconds. <i>sec</i> must be between 1 and 600. Default is 2.
</dd>
</dl>
<h2><a name='sect4'>Exit Codes</a></h2>
<b>svwaitup</b> returns 0 as soon as all <i>services</i> were at least <i>sec</i>
seconds up. <p>
<b>Note</b>: If <b>svwaitup</b> exits 0, it does not guarantee that all <i>services</i>
are actually running. A <i>service</i> could have crashed immediatly after <b>svwaitup</b>
was successfully checking it to be up <i>sec</i> seconds. <i>services</i> should be designed
not to rely on <b>svwaitup</b> to resolve dependencies. <p>
For each <i>service</i> that is
down and not requested to become up, or that causes an error while checking
(e.g. <i><b>runsv</b>(8)</i> is not running), <b>svwaitup</b> increases the exit code by one and
exits non zero. The maximum is 100. <p>
<b>svwaitup</b> returns 111 on error.
