#print
The computer keeps track of information in "files."
A file might contain a letter to a friend,
or a memo (or part of it) that you are typing,
or any number of other things.
You can list the names of your files
by typing the command "ls".
Try "ls" now; then type "ready".
Remember that each command must go on a separate line
and each line must be ended with RETURN.
#create letter
Dear John:
 
I'm terribly sorry...
#create memo
This is a memo.
#create memo1
Another memo.
#copyin
#user
#uncopyin
grep '^ls' .copy >/dev/null
#bad "ls"
Don't type the quotes, please. Try again.
#log
#next
