UNIX processes / daemons & core dumps

[rawebley]

I have written a script that checks for the existence of a particular entry on the process table and then acts upon it accordingly. The script continuously loops and was activated using the "at" command - thus still running when the session is terminated. The only problem is it naturally spawns new processes continously and randomly quits with a core file entry!
1) How do I convert my script into a daemon thus making it less process intensive?
2) How do I read the core file. Unfortunately, the "man" page for core does not exist on my system?

Not sure about the daemon part of it. You could set the script to spawn during startup though via an S file. As for less process intensive? Just nice it to use less CPU time.


Reading core files, use strings or gdb. Go here for gdb:
