Re: {bb} Scripting BB startup/shutdown in Red Hat

["Johann Eggers" <johann.eggers@teleatlas.com>]

Hi,

I use the following simple start/stop script:

#!/bin/sh
#
#       Start script for Big Brother and Tools on LINUX
#
#       Johann Eggers (jeg), 22.08.2002

BBHOME=/opt/bb

case "$1" in

'start')
       su bb -c "/opt/bb/runbb.sh $1"
       ;;

'stop')
       su bb -c "/opt/bb/runbb.sh $1"
       ;;

'restart')
       su bb -c "/opt/bb/runbb.sh $1"
       ;;
*)
       echo "Usage: $0 [start|stop|restart]"
       ;;
esac
