Sudo is "Superuser Do"

I enjoy the etymology of technology words. Understanding it can be a handle into using the tool well. One example: sudo. sudo comes from “Superuser do”, allowing you to run a program with the security privileges of another user, usually the root superuser. Here’s an example from a terminal near you: $ <dangerous-command> dangerous-command: NOT super-user $ sudo <dangerous-command> Doing a dangerous thing... This is why programmers say “su DO” (pronouncing “do” like “do”) rather than the softer “sudo”. They aren’t (just) being pedantic; it’s the more correct way to pronounce the word.
