Mr. Harald,
Thanks again for your reply, I did not have bash-completion installed (and did not know it existed).
I installed it on one of the servers and sure enough res<tab> completes to "restart" now!
Cool, I will be adding that to all my servers and to my new server set-up scripts and notes.
Super awesome feature!
