#print
Often you want to refer to the last line
of a file, and you don't know how long it is.
There is a special address, "$" for this purpose.
"$" refers to the end of a file.  Thus
  $p
prints the last line of a file and
  1,$p
prints all of a file.
Here's another file.  Print all of it, and
then type the usual w, q, and ready.
Your commands should look like
  1,$p
  w
  q
  ready
#create Ref
1,$p
w
q
#create file
