Sending a message to a remote terminal

Question

Is there a way to send a message to a remote terminal similar to using the wall command for other users on the local system? In this scenario I want to specify a username@hostname and have a message appear in their terminal if they are logged in.

Answer 1

You can use the write command to send messages to a specific user instead of to everybody. You can send them over the network using whatever login credentials you already have, usually over ssh like this: ssh youruse@hostname write username to send username@hostname a message.
