wall and write: sending messages to logged users
You can send messages to logged users on a server with several commands: in this tutorial we will learn to use ‘wall’ and ‘write’.
Table of Contents
wall allows to send a message to all logged users.
wall <message> # wall "Test message"
You can also display the contents of a file or standard input. Users will see something like this on their terminal:
Broadcast message from root@localhost (pts/2) (Fri Mar 25 12:33:45 2022): Test message
man wall for more info.
write you can comunicate easily to other users by sending multi-line messages. Just run
write and the username (and optionally, TTY name).
write <username> # write ricardo
Then, write your messages and press Enter to send them. When you are done, type an EOF character (Ctrl + D). The recipient will see something like this:
Message from root@localhost on pts/2 at 12:32 ... test message EOF
The recipient can reply by running
write as well. Run
man write for more info.
