A couple of more general questions on Ubuntu. If I view man page
and get to the end of the discription how do you get out of it. I have
tried "esc", "Delete", and a couple of others and have found that
"Cntl Z" works. Is there something else that works too.
I expect there is a way to edit a .profile and add
something else. Isn't there an echo command to see what the
users environment varibles are set to?
