"I Raised My Kids On the Command Line...and They Love It" - no they don't, most kids just want to play with their paint or chat app or some game. OP's kids haven't actually learned anything other than they had to go through some irrelevant ceremony to get to play with their favourite app. You don't make your kids break out ICE's or hardware debug tools just so they can boot the lounge flatscreen so they can watch Postman Pat. I wish people would stop pretending this is educational for children at this age, it's not. All the kids are doing is spending a bit of time with their Dad, who I'm sure they love, to get to the end result which is to play with TuxPaint.
