Reminds me of my sysadmin days when I was trying to learn shell scripting and would lookup man pages of random binaries in /usr/bin. Before we could bring down a box for nightly maintenance/backup, we would send a shutdown broadcast notice like:
banner "Shutdown"|wall; banner "in 5 mins"|wall
I found out "write" command and setup a hacky little one-to-one chat script - it was terrible and geeky but I really liked it.
I'm probably forgetting some more obscure commands that I enjoyed :)
PS: forgot to mention that when I told my boss about the "write" based scripts, he gloated that he had setup a quiz program which supported multiple participants using named pipes. Awesome guy :)
