Unix-like systems are multiuser, and so you have your own electronic identity
as a user on the system. Type fingeryourusername to
look at some of the information about you that's publically available. To change
the name and shell listed there, you can use the commands chfn and
chsh. Only the superuser can change your login (username) and directory.
You'll notice that it says ``No plan.'' A ``plan'' is just some information
you can make available to others. To create a plan, you put whatever information
you want people to see in a file called .plan. To do this you'll use
a text editor; see section 8.2 on page . Then finger
yourself to see your plan. Others can finger you to see your plan and
to check whether you've received new mail or read your mail.
Note that this finger information is available to the entire Internet by default.
If you don't want this, read about configuring inetd and the file /etc/services.
Eventually the installation manual will describe this configuration, but for
now you might try the man pages or just put nonsense in for your finger information.
