mesg(1)				 User Commands			       mesg(1)

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  de-
       vice.  The  terminal device affected is determined by searching for the
       first terminal in the sequence of devices associated with standard  in-
       put,  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	Denies permission to other users to send message to the	termi-
		nal. See write(1).

       -y|y	Grants	permission to other users to send messages to the ter-
		minal.

ENVIRONMENT VARIABLES
       See environ(5) for descriptions of the following	environment  variables
       that affect the execution of mesg: LANG,	LC_ALL,	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.
