Or "su -l". Of course, if you read /root/.profile, you're going to get
the warning message again (until you change it)!

BTW, to use "shutdown now" or "shutdown -h now" for "reboot" and
"halt" respectively, you only have to be a member of group operator.

fredb-> grep operator /etc/group
operator:*:5:root,fredb,shutdown,johnb,allieb

The whole point of "operator" is to let someone shutdown or make dumps
without having root access. #1 son, e.g. knows how to shutdown &
reboot into MacOS, to play games, but he doesn't need the ability to
read or delete all of my mail.
