Nerd trivia of the day: ever wondered why the dd CLI UI is so much different from the rest of gnu coreutils tools?
No hyphens before operands, weird "=" symbol all over the place.
Turns out this UI was originally meant to be a prank: it uses the IBM JCL[1] notation. A language used on systems which happened to be shipped with a similar tool.
50 years later, the tool is still here, the prank is still here, but nobody gets it anymore: it just became a weird UX annoyance. 😅
