#print
Another use for pipes is to replace a command sequence that we
did earlier with "cat", "pr" and a temporary file.  If you have
a bunch of small files, using "pr" on them directly wastes
paper, since each file takes a page.  You could say
  cat memo* >temp
  pr temp
  rm temp
but this is a nuisance (and the output will
have the title "temp" on each page).  So use
a pipe instead.
In this directory there are some files whose
names begin with "word".  Use "cat", "pr" and a pipe
to print them, then type "ready".
