#print
Your directory contains only one of the following
files: "richard", "robert", "ralph", "roger".  Find out
which one exists, and print the contents of that file
on your terminal (remember the "cat" command?).
Then type "ready".
#create robert
this is the contents of file
robert which you had to print.
#copyin
#user
#uncopyin
grep 'cat rob' .copy >/dev/null
#log
#next
