 NAME
      mesg - permit or deny messages to terminal

 SYNOPSIS
      mesg [[-] g] [[-] y] [[-] n]
      mesg

 DESCRIPTION
      The command form mesg [-] n forbids messages via write by revoking
      write permission to users without appropriate privilege on the user's
      terminal (see write(1)).	The command form mesg [-] g reinstates
      permission so that only legitimate commands (such as write(1)) can be
      used by other users to send messages.  mesg [-] y allows applications
      such as write or talk to send messages to the user's terminal (that
      is, without restrictions).  mesg without any other argument reports
      the current state without changing it.

 RETURN VALUE
      mesg returns the following values:

	   0	Messages are receivable.
	   1	Messages are not receivable.
	   2	An error occurred.

 EXTERNAL INFLUENCES
    Environment Variables
      LC_MESSAGES determines the language in which messages are displayed.

      If LC_MESSAGES is not specified in the environment or is set to the
      empty string, the value of LANG is used as a default for each
      unspecified or empty variable.  If LANG is not specified or is set to
      the empty string, a default of "C" (see lang(5)) is used instead of
      LANG.

      If any internationalization variable contains an invalid setting, mesg
      behaves as if all internationalization variables are set to "C".	See
      environ(5).

 FILES
      /dev/tty*
