MESG(1) 							Linux User's Manual							   MESG(1)

NAME

       mesg - control write access to your terminal

SYNOPSIS

       mesg [y|n]

DESCRIPTION

       Mesg  controls  the access to your terminal by others.  It's typically used to allow or disallow other users to write to your terminal (see
       write(1)).

OPTIONS

       y      Allow write access to your terminal.

       n      Disallow write access to your terminal.

       If no option is given, mesg prints out the current access state of your terminal.

NOTES

       Mesg assumes that its standard input is connected to your terminal. That also means that if you are  logged  in	multiple  times,  you  can
       get/set the mesg status of other sessions by using redirection.	For example "mesg n < /dev/pts/46".

NAME

       mesg - display (or do not display) messages from other users

SYNOPSIS

       mesg [option] [n|y]

DESCRIPTION

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

       Traditionally, write access is allowed by default.  However, as users become more conscious of various security risks, there is a trend  to
       remove write access by default, at least for the primary login shell.  To make sure your ttys are set the way you want them to be set, mesg
       should be executed in your login scripts.

ARGUMENTS

       n      Disallow messages.

       y      Allow messages to be displayed.

       If no arguments are given, mesg shows the current message status on standard error output.

OPTIONS

       -v, --verbose
              Explain what is being done.

       -V, --version
              Display version information and exit.

       -h, --help
              Display help text and exit.

EXIT STATUS

       The mesg utility exits with one of the following values:

            0     Messages are allowed.

            1     Messages are not allowed.

           >1     An error has occurred.

FILES

       /dev/[pt]ty[pq]?
