When you log in in UNIX, you are asked
for your login name and password, and then for the terminal type.
type "xterm" at the terminal type,
or, if you see (xterm) there, press Return.
You should now see a UNIX prompt,
which usually looks like "machine_name%"
The commands I will be telling you
about, as well as the commands in the hw instructions, should be typed
at the prompt.
After typing the command, press Return.
