[sudo-users] sudo with shell aliases ?

| alias shut 'shutdown'

You may try alias shut='sudo /sbin/shutdown'

You can put aliases in the user profile, a file in their home
directory, usually something like ~/.profile.

If you have bash, lookup the manpage section INVOCATION.

As Bob already explained, it' a good question if you really 
want that stuff to be global. However that should work, too, 
if you define the alias in /etc/profile.
