PROCESS PID

Codice per sapere se il processo è ancora attivo: (esempio con lftp) 

function lftp-sleep () {
  # Get PIDs of running lftp processes
  PIDS="$(pidof lftp)"
  if [ -z "$PIDS" ]; then
    echo "Error: lftp not running!" >&2
    return 1
  fi

  # Wait for PIDs to finish
  for PID in $PIDS; do
    while [ -f /proc/$PID/cmdline ] && [ "$(head -c5 /proc/$PID/cmdline)" == "lftp"$'\0' ]; do
      sleep 10s;
    done
  done

  # Shutdown
  echo "lftp-sleep: Shutting down." >&2
  logger "lftp-sleep: Shutting down."
  shutdown -h now
}
