 19.1 echo
 =========
 
  -- Command: echo [-n] message
      (none)
      The echo command may be used to annoy 'screen' users with a
      'message of the day'.  Typically installed in a global screenrc.
      The option '-n' may be used to suppress the line feed.  See also
      'sleep'.  Echo is also useful for online checking of environment
      variables.
