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)).
Edit:

This will notprevent rootfrom sending wall messages
这不会阻止root发送墙消息
回答by aqn
Note that every useron the machine that does not want to see a wallmessage has to do mesg n. Putting mesg nin /etc/profilemight do that for all users.
请注意，机器上不想看到消息的每个用户wall都必须这样做mesg n。把mesg n中/etc/profile可能做到这一点对所有用户。
Alternatively, if you only want rootto be able to run wall, change its permission: chmod 700 /usr/bin/wall.
或者，如果您只想root运行wall，请更改其权限：chmod 700 /usr/bin/wall。
