Code:
ps | grep '[p]hantom DSD.RUN job_jobName'

That's very clever. Is it functionally different (any chance of different output), from the following more pedestrian way you are of course well aware of?
Code:
ps | grep 'phantom DSD.RUN job_jobName' | grep -v grep

Let me give you a perspective on the issue. We have an ETL process that executes for around 1 hour. The script basically checks for the presence of this process and exits at the instant when the ETL process finishes. The problem here is that though the loop exits, we can still see the process in the list thrown by ps -eaf punched immediately after the loop exits. I doubt the issue is with the semantics of the code.

Could you show the output of:
Code:
ps -ef | grep "phantom DSD.RUN job_jobName"

All the previous posts used job_jobName pattern, which obviously is not going to work.

Does changing the code from using (incorrect) job_jobName to (correct) jobname solve the problem? Or is there still a problem?

It's the same. job_jobname is only an alias I'm using in the forum so as to not mention the actual name. Sorry for not mentioning it earlier
