NAME
       mesg - permit or	deny messages

SYNOPSIS
       mesg [-n	| -y | n | y]

DESCRIPTION
       The  mesg  utility will control whether other users are allowed to send
       messages	via write(1),  talk(1),	 or  other  utilities  to  a  terminal
       device. The terminal device affected is determined by searching for the
       first terminal in the sequence  of  devices  associated	with  standard
       input, standard output, and standard error, respectively. With no argu-
       ments, mesg reports the current state without  changing	it.  Processes
       with  appropriate privileges may	be able	to send	messages to the	termi-
       nal independent of the current state.

OPTIONS
       The following options are supported:

       -n|n  Deny permission to	other users to send message to	the  terminal.
	     See write(1).

       -y|y  Grant permission to other users to	send messages to the terminal.

ENVIRONMENT VARIABLES
       See environ(5) for descriptions of the following	environment  variables
       that  affect the	execution of mesg: LC_CTYPE, LC_MESSAGES, and NLSPATH.

EXIT STATUS
       The following exit values are returned:

       0     if	messages are receivable.

       1     if	messages are not receivable.

       2     on	error.
