Well, it looks like you've changed perms on the sudo executable.
Should be

Code:

 ll /usr/bin/sudo
---s--x--x 1 root root 212904 Jul 21  2011 /usr/bin/sudo

Is there any sort of error you are getting? It would be easier to help if you post the error and the distro you are using

Thanks for the help and i am using ubuntu 11.10 but you are exactly right, the permissions are changed for sudo and a lot of others but I don't know how to change them. I used recovery mode so I was root and it said it was read only so I couldn't change it. So I am probably missing something obvious

Linux is case sensitive; that's a lowercase 's'
