[X4U] Using su and sudo f rom the terminal

[Doug McNutt]

su, as opposed to sudo, changes the user of the Terminal.app to the 
superuser for as long as he likes. The prompt changes and several 
commands behave differently. (ls is always ls -a for instance.)

A separate password is used which is not your admin password.

"Applications/Utility/Netinfo Manager" is where you can set a 
superuser password but the user interface is not easily navigated. 
They call it "enable root user" and "set root password" in the menus. 
After a while you'll swear that Steve doesn't want ANYONE to use it.

Someone has probably written a how-to. Google?
