That should probably be enough for now.
With all that theory your head is probably pounding. Tomorrow
we will start doing some more learn by example things. But before we
stop for today, I want to mention one command which you
can use to chage your password once you've logged in.
Many times, your sysadmin will give you a default password and instruct you
to change it as soon as you log in for the first time.
To change your password, simply use the "passwd"
utility. To do so, simply type "passwd" at the comand prompt and answer
the questions. UNIX will ask you for your new password and ask you to
type it in twice to make sure there were no typing errors. It
may also ask for your old password for verification.
