need to use sudo in script
I need a simple script that will delete the boot cache file at /private/var/db/BootCache.
sudo rm /private/var/db/BootCache.
my goal is to put this into a logout hook so the computer doesn't freeze on reboot... i need this script to run as any user.
any help would be great.

You've already been given a solution, but I just wanted to clear up a misconception.
When you run sudo, it isn't prompting for the root password, it's prompting you for the password of the user you are running sudo from.

Did you try my comment? It's easy, probably the best AND SAFEST way to do things in your situation and there's no need to learn the /etc/sudoers syntax.
When a setuid bit is set to an executable, the script will be executed as if it was executed by the owner of the file - simple. One chmod command and you're good to go.
Anyone have any cons to solving the OP's question this way ?

Well, unless OS/X is the exception to just about all other Unix/Linux flavours, then setuid bits on scripts are ignored.
