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 arguments,
      mesg  reports  the  current  state  without   changing   it.
      Processes  with  appropriate  privileges may be able to send
      messages to the terminal 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.

      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.
