	If you want to clean this up and not spawn so many uses of grep, 
you can try something like the following:

		if ps axw | egrep 'q[r]unner'

	This will have the same effect as the longer string above, so 
long as the script has the string "qrunner" somewhere in the name. 
If you want to understand why this works, check the man page for 

	You could also start a script like this on boot or from cron, 
using locking to make sure there is only ever one copy of the program 
running, and then have it sleep for a reasonable period of time 
between checks.
