Bash Scripting Question


Hey,

I want to write a simple script that checks to see if aMule is running, and if it is not running - activate the program.

My main directions are using grep somehow, though simply typing "ps ax | grep amule" always gives some answer (even if amule is not running).

I'd appreciate any help.

Tnx,
fiod

What answer does it give you if it's not running?

Code:
[ `pidof -s amule` == "" ] && amule

When making
Code:
 ps ax | grep pattern
, you always get the line "grep pattern" because "grep pattern" contains "pattern", so
Code:
 ps ax | grep amule | grep -v grep
could do the trick

would you mind posting your resulting script? I'd like to have a look at it and see if I can adapt it in some way to check the kppp demon is running. It's crashing on me every 1 or 2 days and it would be nice to be able to keep a tab on it, close all kppp related threads , restart and reconnect automatically (as opposed to finding out kppp crashed 5 minutes after I went to bed while trying to do a 'yum update')
