Broadcast message from [email protected] (pts/1) (Thu Jun 6 08:05:02 2019):
hello
How has this messagen been sent to me? And how can I reply to it?
Aside from the concerns that you host might be compromised, to broadcast a message to all users or users in a specific group, use wall
wall -g root "Hi there"
# Will send to all users in the root group
wall "hello, world"
# Will send to all logged in users
Also checkout mesg and talk.
