     NAME
          mesg - permit or deny messages

     SYNOPSIS
          mesg [choice]

     DESCRIPTION
          mesg permits or denies receipt of messages sent by another
          user via write(1).  With no argument, mesg reports the
          current permission state.  The choice arguments may be ei-
          ther y or n.

          mesg with choice n forbids messages by revoking nonuser
          write permission on the user's terminal.  mesg with argument
          y reinstates permission.

     EXAMPLES
               mesg y

          changes the permission to ``yes'' and the system reports:

               Is Yes; Was No

          or whatever is the current and former state of your message
          permission.
