Did I include this program under fun because body parts are funny? Indeed.
The finger
program is used to find out information about a specific user
given their username. The command syntax is finger username
.
I’m sure you can think of the word that Unix uses to describe this incredibly
appropriate action.
[euid123@talon3 ~]$ finger euid123

No Plan.
As you can see, you can use finger
on your own username as a way to check to
see if you have mail.
Additionally, you can update your personal information that appears with
finger
using chfn
.
Some system administrators block you from changing this information, though, so
knowing this probably isn’t very helpful.
