Need Help??

I've had the output of ps change on me in a distro version update. But, actually, you're probably right, I wasn't using a POSIX or BSD output format. That would stabilize it.

And yes, /proc isn't portable. It might be a little bit portable. I know it's optional on OpenBSD, for instance.

Looking for the same process name twice won't help. I want to know the age. I think I'll add an example to the OP.

Good point about POSIX or BSD ps output.

cron

try to open /tmp/monitor_info
if non-existent, generate pid/procname list, write to /tmp/monitor_info and exit
read file data into array/hash
generate pid/procname list using aforementioned ps command
compare lists. If same pair shows up in both, kill it (it's been running longer than 10 minutes).
write new list to /tmp/monitor_info

/tmp/monitor_info

This script is short and easy. Does that make sense?
