#print
To create a second copy of a file, the easiest
way is to use the "cp" (copy) command.
If you tell the computer
  cp x y
a copy of file "x" is made and named "y".
Note that this is similar to "mv" in that a new
file named "y" appears, but the difference is
that the old file is not removed.
(If there was already a file named "y", though, the
old contents are lost; be careful.)

In this directory there is a file which has
a five letter name whose first four letters
are "part".
Print it out; it will tell you to copy
it and what to call the copy.
Do that and then type "ready".
#create X1
#create george
#create part00
this is not the right file and you shouldn't
have printed it.  Use
 part?
not
 part*
in this example.
#create part3
This is the file "part3".  I hope you
used a command like
  ls part?
or
  cat part?
to find it.
Make a copy of this file on file "george".
#user
#cmp george part3
#log
#next
