How can I record the PID number returned by this code in a bash variable? For a reason unclear to me, stdout does not seem to be recorded in this example: RESULT="$(./start_and_get_pid.out echo yo)"; echo "$RESULT"

@Tfb9: I'd honestly recommend one of the other approaches; I wrote this 2+ years ago and it's by far one of the hackier/error-prone methods presented (or so I think).

Thanks for the note. I think I solved my problem with this sleep 10 & PID_IS=$!; echo $PID_IS
