Messed up visudo - can't edit the file anymore

http://askubuntu.com – I really did some very stupid stuff. I did a sudo visudo and wanted to add the following line: %admin ALL = NOPASSWD: /bin/tar so users can execute /bin/tar without the need to sudo. But stupid me replaced the line %admin ALL = (ALL)ALL So basically that means I'm totally locked out. Everytime I try a sudo visudo I get "Sorry, user admin is not allowed to execute '/usr/sbin/visudo' as root on myhost" I only can tar. Great. Is there any way to get my root rights back? (HowTos)

visudo syntax error 22 weeks 8 hours ago

What am I doing wrong here as this line is making visudo fail

dhiller2 ALL= ALL, !NSHELLS, !NSU NOPASSWD: ALL

this line works

dhiller2 ALL= ALL, !NSHELLS, !NSU

How to fix this?

and yes, I know there are ways to get around this...this is just to remind our admins that policy is not sudo su - and you should be using sudo to run all commands.

thanks, Dean
