I got the idea from the script > for upsd off of ftp.ww.com. Don't forget that anyone in group operator can run shutdown too. The permissions on /sbin/shutdown are: -r-sr-x--- 1 root operator 139264 Jul 13 19:38 shutdown* I do it all the time without su'ing to root. That way you don't comprimise system security quite so much. You could create a dufus account that is in operator but only can run shutdown.
