MESG(1)				 User Commands			       MESG(1)

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

SYNOPSIS
       mesg [option] [n|y]

DESCRIPTION
       The  mesg  utility  is invoked by a user to control write access others
       have to the terminal device associated with standard error output.   If
       write access is allowed, then programs such as talk(1) and write(1) 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.
       To  make	 sure  your ttys are set the way you want them to be set, mesg
       should be executed in your login scripts.

ARGUMENTS
       n      Disallow messages.

       y      Allow messages to be displayed.

       If no arguments are given, mesg shows the  current  message  status  on
       standard error output.

       -v, --verbose

       -V, --version
	      Display version information and exit.

       -h, --help
