       mesg - display (do not display) messages from other users

       mesg [options] [n|y]

       The  mesg  utility is invoked by a users to control write access others
       have to the terminal device associated with the standard error  output.

       may display messages on the terminal.

       Traditionally, write access is allowed by default.  However,  as	 users
       become  more  conscious	of various security risks, there is a trend to
       remove write access by default, at least for the primary	 login	shell.

       should be executed in your login scripts.
