I'm writing a web service that accepts a call to initiate a few self-contained scripts on a RHEL4 webserver. Being new to Ruby, I can't seem to find any documentation on how I could kick off the scripts without having the parent script wait on them to complete. Obviously, I don't need arguments our output back from the scripts, so all I'm concerned with is that they start and the parent can end without killing them. What's the best way to do this?
