let's say in my office i have 20 networked sun boxes named host1 through host20. i am currently logged in as root at some random machine, which we will say host13 for this scenario's sake. now, is there any way i can send a text message of some sort over the whole network to all logged in computers at once. i've been at this for days trying to figure out how to do it. im probably just having a brain fart, but could somebody please tell me in detail the command to do this
You can use "rwall host1 host2 host3...." to send a message to all the hosts at once.
