<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>
[-P] <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, or symlink
to a directory, in the services directory <i>dir</i>, up to a limit of 1000 subdirectories,
and restarts a <i><b>runsv</b>(8)</i> process if it terminates. <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 whether the time of last modification, the
inode, or the device, of the services directory <i>dir</i> has changed. If so,
it re-scans the service directory, and if it sees a new subdirectory, or
new symlink to a directory, in <i>dir</i>, it starts a new <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 daemontools’ <b>readproctitle</b>
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.
<h2><a name='sect3'>Options</a></h2>
<dl>
<dt><b>-P</b> </dt>
<dd>use <i><b>setsid</b>(2)</i> to run each <i><b>runsv</b>(8)</i>
process in a new session and separate process group. </dd>
</dl>
<h2><a name='sect4'>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.
