Check to see if a process is already running

[HackerJL]

I have a hazel script set to run an automator action, which is fine.

My automator script feeds a terminal command with variables, works great.

What I am worried about is that I would like hazel to NOT run the automator script if the process is already running. So I assume I would need to check via a shell script, to see if process X is already running. If so, dont run it.

If it is not, then run it. Can someone point me in the right direction for a shell script to see if a process is running?

You can try using something like:

ps -auwx | grep NAME OF PROCESS

where NAME OF PROCESS is the name of the process.

I'd use "ps -acx …", as explained here.

Ah yes, good point.
