I need to be able to determine if a certain process, (that contains certain values in the pid line such as contents of $version and "online"), is running by obtaining the PID. In csh, I issue the statment:

pid=`ps -ef | grep $version | grep online| awk '{print $2}'`

If pid is null, then I know the process is not running and I need to restart it.

I am rewriting a number of these csh pgms in perl but am fairly new at this. If I issue the system command, I only seem to get a return of '0'. Any help you can provide is greatly appreciated. Thank you.
