I am writing one shell script and I want to get PID of one process with name as "ABCD". What i did was :
process_id=`/bin/ps -fu $USER|grep "ABCD"|awk '{print $2}'` This gets PID of two processes i.e. of process ABCD and the GREP command itself what if I don't want to get PID of GREP executed and I want PID only of ABCD process?
Please suggest.

In this quick article, we've explored how to get the name and the command line of a given PID in the Linux command line. The ps -p <PID> command is pretty straightforward to get the process information of a PID. Alternatively, we can also access the special /proc/PID directory to retrieve process information.
The easiest way to find out if process is running is run ps aux command and grep process name. If you got output along with process name/pid, your process is running.
Just grep away grep itself!
process_id=`/bin/ps -fu $USER| grep "ABCD" | grep -v "grep" | awk '{print $2}'` If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
