The terminal will hang around as long as any process has an open descriptor connected to it. "disown" does not (and cannot) disconnect an already-running process's file descriptors from the terminal. It only affects the relationship between the process and bash, not between the process and the terminal. > It seems like it's hanging on stdout since redirecting to /dev/null fixes the > problem.

See if this works: (tail -f < /dev/null 2> /dev/null | $NETCAT -l -p $LISTENPORT >> $LOGFILE 2>&1) & paul
