in reply to Creating External Processes without losing control

I was under the impression that doing an "exec" would simply start the process and leave it. By not waiting for a return value, you should be able to continue processing. Unfortunately, I don't generally do a whole lot with system and exec calls, but perlipc (perldoc perlipc) does :) Thanks

    exec does not start a new process. exec replaces the current process with a new process executing the given executable. A successful exec will never return, as the original process's code is no longer executing. exec is often combined with fork to split off a child process and cause that process to execute the given executable.
