PMS Autostart on a Headless System

While installing and configuring Wuala to start automatically on my headless server, I figured out I can use the same mechanism for PS3 Media Server (AKA PMS). So here the init.d script for PMS:

#!/bin/bash

### BEGIN INIT INFO
# Provides:          pms
# Required-Start:    $network $local_fs
# Required-Stop:     $network $local_fs
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: start pms headless
### END INIT INFO

PMSUSER=pmsuser
PMSDIR=/home/pmsuser/pms
BACKPWD=`pwd`

case "${1:-''}" in
  'start')
        # start commands here
        echo "Starting PMS..."
        cd $PMSDIR
        su $PMSUSER -c "screen -d -m $PMSDIR/PMS.sh"
    ;;

  'stop')
        # stop commands here
        echo "Stopping PMS..."
        p=`ps -ef | grep java | grep pmsuser | grep pms | awk '{print $2}'`
        if [[ "$p" = "" ]] ; then
                echo "PMS not running"
        else
                kill $p
        fi
    ;;

  'restart')
        # restart commands here
        $SELF stop
        sleep 5
        $SELF start
    ;;

  'status')
        # status commands here
        p=`ps -ef | grep java | grep pmsuser | grep pms | awk '{print $2}'`
        if [[ "$p" = "" ]] ; then
                echo "PMS not running"
        else
                echo "PMS running with PID $p"
        fi
    ;;

  *)
        # no parameter specified
        echo "Usage: $SELF start|stop|restart|status"
        exit 1
    ;;
esac

cd $BACKPWD
