mesg: Enable receiving messages from the write command.
$ mesg y
try on your machine
The command mesg y
is used to enable receiving messages from other users on the same system via the Unix/Linux terminal.
By default, when you log in to a Unix/Linux shell, the system allows other users to send you messages. The mesg
command controls this feature, and the option y
is used to enable it.
When you execute mesg y
, it allows other users to send messages to your terminal by using the write
command or the talk
command.
On the other hand, if you use mesg n
command, it disables receiving messages from other users.
This feature is often used for communication between users or to send important notifications to other logged-in users.
