The result information contains the process ID. Note that on Unix the command must not end with & or the result will be empty. Once you have the process id your can use a spawn to ps, parse the output to check whether the process is alive. Since the spawn process is blocking, you may have to use the IDL Bridge of you want your application to continue.

What I would like to know is how can I tell if the process completed on its own or was terminated. I've tried including RESULT and ERROR in the call, but they both return empty strings.
