Question about using pid

[Janina Sajka]

I have a command that starts a process. Should that process die whilst
I'm not at my computer, I want a script to restart it.

How do I do this? What doc might I read that would provide examples?

I presume I should launch the process so that it's pid is written to a
file, and then I can just test for the running pid?

But, I don't know how to go forward with this, so would appreciate all
advice and direction.
