"finger" is a useful network tool that can help you find out if someone is
currently logged in to their account, learn more information about a specific
account, and look for friends and colleagues on the Internet.  You can
finger a login name, i.e., consult@uclink2 or a real name, i.e., john.

To see a list of everyone who is currently logged in to another computer,
you can use "@computer_name" i.e., @uclink.berkeley.edu.
