In this short article I show you, how you can extend the functionality of the command line se with your own script.

#!/bin/bash
cmd="$1"
chmod +x "$cmd"
echo "Starting '$cmd'">nohup.out

#(exec nohup $cmd ) 2>/dev/null &
nohup /bin/bash -c "$cmd" </dev/null >nohup.out 2>&1 &

cmd_pid=$!

timeout=120 # seconds

echo "Script was started in background, showing output for max $timeout seconds:"
timeout $timeout tail -f nohup.out &
timeout_pid=$!
wait $cmd_pid
retval=$?

printf "$retval" > /tmp/retval_port_$PORT                                                                 # ie. /tmp/gotty/retval_port_8091
echo "$(basename $0): Done with retval of: $retval for port: $PORT"

if [ "0" -eq "1" ]; then 
	echo "UID        PID  PPID  C STIME TTY          TIME CMD"
	ps -ef | grep '[Tt]ail -f'
fi

kill $timeout_pid
