I presume we're using a very liberal definition of the word "learn" here; I couldn't even memorize these commands when I was 10, I reckon if you quizzed them again in a week they'd have forgotten all about it.

I still have my times tables memorized decades later. Frequent use is the key, if the parent regularly engages with their child in this way I expect they'd remember them for years.

My six year old can quote parts of her books she's read exactly once, six to twelve months ago. She's not special in that regard. You'd be surprised at just how much information a kid can memorize - it's the on-demand recall that tends to be more hit and miss, and I'd suggest that's more to do with the sheer amount of new stuff they have on hand all the time. Hard to query the index as it's being rebuilt.

But give the kid the right context cues, and they can take off running. My daughter knows Bash. She always stares blankly at the first minute, but with someone able to get her started, she'll be back to writing her CYOA game in about five minutes.

Learning isn’t really about memorization

The term "muscle memory" is apt. I've been typing shell commands for 40+ years now. VIM commands for the last 30. They are as natural as brushing one's teeth. I learned them when young and never forgot.

Please locate the git commit that fails this test without googling.

git bisect start [last working commit] [earliest broken commit]

git bisect good/bad

E: I mixed the commits up. The irony

Knowing the exact syntax of git bisect isn't that useful when you use it quite rarely. Knowing that git bisect exists and that it does what you need is the real knowledge.

I got a laugh from this about tar https://xkcd.com/1168/

just let your toddler to save some porn in that dirs and you'll see if he needs your help in the next time.
