     mesg [y | n]

DESCRIPTION    [Toc]    [Back]

     The mesg utility is invoked by a user to control  write  access others have
     to  the  terminal  device associated with the standard error
output.  Write
     access is allowed by default, and programs such  as  talk(1)
and write(1)
     may display messages on the terminal.

     The options are as follows:

     n       Disallows messages.

     y       Permits messages to be displayed.

     If no arguments are given, mesg displays the present message
status to
     the standard error output.

     The mesg utility exits with one of the following values:

            0    Messages are allowed.
            1    Messages are not allowed.
           >1    An error has occurred.
