Is there a way to cancel a job/script via the command line? (4291583)

Some users will prefer to use a scheduler like cron job to run the QSA scheduled jobs on the command line. However, the document does not include how to cancel the script

Run sqlplus and connect as the installing QSA Oracle user:

begin
quest_exec.cancel_script('owner','folder','script_name');
end;
/

This will cancel the script named owner.folder.script_name. If the script is not running or does not exist, the user defined Oracle error 20304 will be raised. It is up to the user to capture this and to take the appropriate action. This is something that is provided by QSA, but not easy for the end user to do.
Thanks
