write is a Unix/Linux command that sends a message to the terminal of another user logged in to the same system. You specify a user name (and a tty if needed) and type text on standard input, which is printed as-is on the other user's terminal; the recipient can allow or block messages with mesg. It is an old terminal messaging tool paired with wall, which sends to all users at once.
