<h2><a name='sect0'>Name</a></h2>
runsvdir - starts and monitors a collection of <i>runsv(8)</i> processes
<h2><a name='sect1'>Synopsis</a></h2>
<b>runsvdir</b>
<i>dir</i> [ <i>log</i> ]
<h2><a name='sect2'>Description</a></h2>
<i>dir</i> must be a directory. <i>log</i> is a space holder for
a readproctitle log, and must be at least seven characters long or absent.
<p>
<b>runsvdir</b> starts a <i><b>runsv</b>(8)</i> process for each subdirectory in <i>dir</i>, up to
a limit of 1000 subdirectories. <b>runsvdir</b> skips subdirectory names starting
with dots. <i><b>runsv</b>(8)</i> must be in <b>runsvdir</b>’s PATH. <p>
At least every five seconds,
<b>runsvdir</b> checks if <i>dir</i> has changed. If it sees a new subdirectory in <i>dir</i>,
it starts a new <i><b>runsv</b>(8)</i> process. If it sees an old sudirectory where a
<i><b>runsv</b>(8)</i> process has exited, it restarts the <i><b>runsv</b>(8)</i> process. If <b>runsvdir</b>
sees a subdirectory being removed that was previously there, it sends the
corresponding <i><b>runsv</b>(8)</i> process a TERM signal, stops monitoring this process,
and so does not restart the <i><b>runsv</b>(8)</i> process if it exits. <p>
If the <i>log</i> argument
is given to <b>runsvdir</b>, all output to standard error is redirected to this
<i>log</i>, which is similar to the <i><b>readproctitle</b>(8)</i> log. To see the most recent
error messages, use a process-listing tool such as <i><b>ps</b>(1)</i>. <b>runsvdir</b> writes
a dot to the readproctitle log every 15 minutes so that old error messages
expire. <p>
Normally <b>runsvdir</b> is started by <i><b>runit</b>(8)</i> in stage 2.
<h2><a name='sect3'>Signals</a></h2>
If <b>runsvdir</b>
receives a TERM signal, it exits with 0 immediately. <p>
If <b>runsvdir</b> receives
a HUP signal, it sends a TERM signal to each <i><b>runsv</b>(8)</i> process it is monitoring
and then exits with 111.
