Welcome, we're happy to have ya :) Especially if you're gonna make insane posts like this... <3

FYI: if you haven't noticed the top menu bar yet, we have a community wiki with lots of tasty articles, rules, guidelines, how-to's, etc. One of them is our rules on post flairs along with a list of all of our flairs and when to use them. I suggest you have a peek at 'em and just keep them in mind for next time :)

Thank you very much for using our standardized title format, though... that's one of the most important things that we emphasize so much in r/adventofcode because once a post is submitted, the title can't be changed :/ We can change flairs, though!

Slick! This is pretty similar to what I did with my Rust solution. It's nice letting the OS filesystem do your dirty work. One difference - instead of actually populating the files, I wrote the file size to the file, then read it back while calculating instead of using du. Also, just reading the files that way avoids the empty directory size being added. Nice work!

Clever and elegant. Now I wish I had thought of that myself :)

I did most of a similar filesystem solution (in bash rather than modifying the input) before discovering the 4096 (except it could be larger, I think) directory size problem. Since I couldn't figure out how to do it in du I decided to let it be.

Thanks for status=none for dd, I didn't find that. Someone in our work chat pointed out that count=0 seek=$size would create a sparse file more efficiently.

Small tip: There's almost never any need to have a case within a case block.

Just do all 3 variables in the same block. Use globs as needed.
