Execute commands as another user

This of course only works if you an administrator. You can't su to root or any other user if you are not an admin on the box.

Execute commands as another user

Only users in group "wheel'' (normally gid 0) or group "admin'' (normally gid 20) can su to "root''.

The su command will work as ANY user, regardless of privilege. If I am logged in as "sam" and wish to execute commands as "joe", I type:

su joe

and then enter the password for the user "joe". No admin privileges necessary, just password knowledge.

I frequently use this command on UNIX-like machines to help friends or perform some tasks when they are logged into the machine. I often su to my account to access a file, for example.
