Running an external process, not waiting for a return, and obtainingits PID

I need to rerun an external process every 5 minutes and destroy the old one.

The only way I can think of doing that is by running the external
process, not waiting for its output, obtaining the PID, and then
sleeping for 5 minutes before killing the process.

What might be the best way of doing either?
