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: Oh. We do. Oopsie!
gollark: ```osmarks@fenrir /d/p/memes-or-something [123]> git beesgit: 'bees' is not a git command. See 'git --help'.The most similar command is rebase```
gollark: git bees
gollark: I have to say, manually checking the times and running the transactions for every action is REALLY quite irritating.
