Usage
It is invoked as:
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
gollark: Mostly Sascha, Rph and Tako as far as I know.
gollark: All kukiteam people, whatever, or at least the involved ones.
gollark: *All* of you, this isn't really on Tako.
gollark: Kind of impressive that you managed to muck it all up so dramatically.
gollark: Anyway... this is significantly reducing my trust in Kukiteam, I must say.
