UNIX/Linux BTEQ processes can be killed by issuing a kill command from another process. In order to give BTEQ the ability to gracefully exit and set a non-0 return code for its own process, the kill must send a trappable SIGTERM signal rather than a non-trappable SIGKILL signal. Either of the following variations of the kill command (where "PID" is replaced with the actual process id for the instance of bteq) will cause a trappable SIGTERM to be sent:
kill PID kill -15 PID
