The shutdown messages on the Mac/Linux command line are baked into the /sbin/shutdown executable.

This replaces the messages with suitable Mad Max: Fury Road quotes. You can make your own, but since you're patching a binary file the replacements MUST, I repeat MUST be exactly the same number of characters as the original, or your computer will not ride eternal, shiny and chrome.

The two versions below are for a Ubuntu Linux variant, and Mac OS X Yosemite (both versions Work For Me on at least one machine).
