Mesg

 ( Unix User Management And Support-related Utilities ) 

'''mesg''' is a Unix command that sets or reports the permission other users have to write to the current user's terminal using the talk and write commands.

mesg y|n

The 'y' and 'n' options respectively allow and disallow write access to the current user's terminal. When invoked with no option, the current permission is printed.

Input redirection may be used to control the permission of another TTY. For example:

% mesg is y % tty /dev/tty1 % mesg < /dev/tty2 is y % mesg n < /dev/tty2 % mesg < /dev/tty2 is n % mesg is y
