Are you sure this is line 36? It seems like this wouldn't be the one
failing, but one where you were trying to use the value of $procid.
- From the behavior you are observing and the error message, I'm guessing
that you are getting multiple pids back from your process search, which
is tripping-up your script. You might want to plan for multiple pids
coming back and take appropriate action.
Note that you can use $! to get the pid of the last-executed background
command., rather than trying to use your messy ps | grep | awk solution.
Not sure if there's a better way to see if it's already running. Most
scripts like this use a pidfile somewhere to store the pid of the
previous execution, and shutdown scripts remove that file. It's crude,
but it usually works.
