#print
A very useful command in the UNIX editor
is the 'm' command, which moves a lot of
lines from one place to another in a file. For example, 
  5,10m20
picks up lines 5 through 10 and moves them after line 20.  Try
that on the file "list" in this directory: move lines 5 to 10 after 
line 20, rewrite the file, and type "ready".
