<div class="userStyles" style=" font-family: Arial; font-size: 12pt; color: #000000;">The only AI I have messed around with is: AI::NaiveBayes. I have yet to find any use for open AI because I guess I lack the imagination to find an interesting but sometimes inaccurate chat bot useful. Am I missing something?

<p>I like Andy's PID file suggestion, but I would be inclined to make this a bash script rather than a perl one-liner and test something like:</p>
<p>`ps aux | grep perl | grep starman`</p>
<p> </p>
<p>And if that command causes it's own failure (by always creating a process with 'perl' and 'starman') then:</p>
<p>`ps aux | grep [p]erl | grep [s]tarman`</p>

<p>If you find bash scripting not super easy (like me), ChatGPT is very helpful. It's helped me a lot in writing better admin scripts.</p>

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> </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. </div>
<div> </div>
<div>When I do:</div>
<div> </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" moz-do-not-send="true">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>
</div>
<div>RESULTS IN:</div>
<div> </div>
<div>Starman is already running<br>
<br>
<br>
starman 203805 1 0 Nov08 ? 00:00:00 /lib/systemd/systemd --user<br>

" 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 544385 544384 0 23:11 pts/0 00:00:00 ps -ef<br>
starman 544386 544384 0 23:11 pts/0 00:00:00 grep starman</div>
<div> </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> </div>
<div>Anyone know a good solution to avoid this so that I can determine whether my starman startup script is indeed running?</div>
