Запустите скрипт с экрана

Я пишу скрипт для запуска p2pool. Не могу понять, как добавить прогу через "screen -dmS"?

   #! /bin/sh
   ### BEGIN INIT INFO
   # Provides:          p2pool start

   # Default-Start:     2 3 4 5
   # Default-Stop:      0 1 6
   # Short-Description: Auto init p2pool start
   # Description:       Auto init p2pool start via booting system
   #                    placed in /etc/init.d.
