How to check for specific process running through shell
Hi
I want to check whether specific process is running or not through a shell script.
ps -ef | grep will tell me this, i tried this way in shell

cnt =`ps -ef| grep xyz | awk '{ END {print NR}}`

if it return two rows, job is running else not.

Is there any better way of doing this.

Code:
ps -ef | grep inetd | grep -vc grep

This will print out the number of running instances of the process that you are checking for.
