    Broadcasting a message?

    If I'm logged into a computer as root, is there a command where I can broadcast a message to all the other users on the computer? If so, how does it broadcast to someone in X?

    Don't know about via X, but on the command line if you wanted to say Hello users to everyone you could use
    Code:
    wall "Hello users"

    If you want to specify a username, etc. you can use the talk command:
    Code:
    talk <username>
    It can set up a two-way "conversation".

    good point, and the walking is good excercise. But walking doesn't confuse people who are using Linux for the first time as I'm trying to do. To that end, any good ideas? I've already exhausted ejecting coworkers' cdroms remotely.
