Need to expand your grep RE or add a grep -v to remove the ones you don't want, though, then you have to remove the one you just added. Another is to track the pids, find the ones you've created and look for one outside that set. You could have starman (if
it doesn't) create a .pid file and use that to check that pid's status (with lsof -p <pid> maybe), rather than grepping.</div>

<div dir="ltr">Hello everyone,
<div><br>
</div>
<div>So excited about the Winter Perl Conference that I just registered for that I thought I would rebuild my aged Perl Dancer2 website. I 've done so and deployed it on a Digital Ocean droplet but I've hit a snag in setting up a cron job to make sure starman
is running. It seems my query into whether the process is running gets treated as evidence that the process IS running. <br>
</div>
<div><br>
</div>
<div>When I do:</div>
<div><br>
</div>
<div>perl -e 'my $smstat = `ps -ef | grep starman`; unless ($smstat =~ /starman master/) { system("XDG_RUNTIME_DIR=/run/user/1001 exec /home/starman/<a href="http://starman.pl">starman.pl</a> start &>> /home/starman/starman.log"); print localtime . " starting
starman\n"; } else { print "Starman is already running\n\n\n $smstat\n" }';<br>
<br>
</div>
<div>RESULTS IN:</div>
<div><br>
</div>
<div>Starman is already running<br>
<br>

starman 203805 1 0 Nov08 ? 00:00:00 /lib/systemd/systemd --user<br>

print localtime . " starting starman\n"; } else { print "Starman is already running\n\n\n $smstat\n" }<br>
starman 544384 544383 0 23:11 pts/0 00:00:00 sh -c ps -ef | grep starman<br>

starman 544386 544384 0 23:11 pts/0 00:00:00 grep starman<br>
</div>
<div><br>
</div>
<div>It always says it's running even if it is not apparently because it's seeing 'starman master/ in the perl script that is inquiring. </div>
<div><br>
</div>
<div>Anyone know a good solution to avoid this so that I can determine whether my starman startup script is indeed running?</div>
