An OIT/IDRE consultant sent me an email about a lot of left over jobs running under my userid. How do I delete them?

You can get the processor id’s using the ps command and filter them using the grep command to select only the jobs you want to delete and feed the result to kill command.
ps -u loginid | grep myjob | awk '{print $1}' | xargs
ps -u loginid | grep myjob | awk '{print $1}' | xargs kill Replace loginid with your loginid and myjob with the executable name.
