PID files have one annoying shortfall: unlinking the file leaves you unprotected.
pgrep makes it simple enough to scan for a running proc by path and args, e.g.
pgrep -f 'starman.*master,*8080';
and saves you from dealing with stale files, accidental unlinks, etc.

Hey Steve,
Great to hear from you. Thanks for the reply. I ended up doing something similar: pgrep -w "starman master"
Let's meet up Quenchers at 5pm for a quick beer! :)

Subject: [Chicago-talk] Experiences with AI/OpenAI API access with Perl?
Message-ID: <a524d205fbd886ec5b869728a79ab41f@alanmead.org>
Is anyone using OpenAI (or any of the many compatible APIs) with Perl? I
have rolled my own code to do research like this:
https://jattjournal.net/index.php/atp/article/view/173204
But I'm wondering what others are doing?
I had a longer summary, but suffice it to say that I've had limited
success with OpenAI::API and OpenAPI::Client::OpenAI, and I'd rather use
Python (this isn't my day job and I'm annoyed ever time I use Python). I
think what I'd like is an OpenAI::Tiny::API or OpenAI::TinyAPI that
handles chat completions and doesn't have dozens of dependencies.
