I recently added two users to my system. I wnat to give them the ability
to shutdown/ reboot without having to su to root, so I added them to
the /etc/sudoers file:
user1 MachineName = NOPASSWD: /sbin/halt, /sbin/shutdown, /sbin/reboot

I then added the alias commands to user1's .bashrc file:

alias halt='sudo halt'
alias shutdown='sudo shutdown'
alias reboot='sudo reboot'

Everything works fine for user1.

Then I added user2; same commands and syntax in /etc/sudoers and
user2/.bashrc.
However, the aliases for user2 don't work. All I get is
'-sh: halt:command not found.'
I can use 'sudo halt,' etc., from the command line, but the aliases
don't work.
The permissions on the .bashrc files is the same, and each user owns their
respective .bashrc.
Does anybody have any suggestions to help me out?

Debian Sarge is the distro involved.

This is kind of important. I'm trying to get a Very Important Client
(aka My Wife) to change her mind about using Linux. The more things I can
simplify, the more she'll like it.

Thank you
