The Single Most Useful Thing

Regardless of how this... paint-splooge, or whatever the noun is for posting on Coderwall makes you feel, here is a response for people who can't read:

where i went

All of this for free? And not in Bash? WTF? I must be drunk because Seashell 7.5.11 gives me this for free.
