### END INIT INFO

case "$1" in
  start)
    screen -A -m -d -S css-beta-server /root/css-server/srcds_run -game cstrike +map de_dust2 +maxplayers 32 -port 27015 -tick 100 
    echo "css server started"
    ;;
  stop)
    screen -S css-beta-server -X quit
    echo "server stopped"
    ;;
  *)
    echo "Usage: /etc/init.d/startupcss {start|stop}"
