    A simpler solution is su root, then run your commands then ^D to get out. Contrary to what some folks say there is nothing intrinsically wrong with conducting commands as root, you just need to take great care, and think before you push key. If your very concerned, put your commands in a shell script and fire that off as root. The more you do stuff the more confident you become.
    best of luck, OBB
