While tac is handy (and amusingly named), I don't think it's
what you want. The reason is that the find output order
isn't deterministic. It's in the directory entry order,
which depends on when the directories were created.
Technically, it's a reasonable bet that a sub-directory will
be created after the parent directory. But reasonable bets
still involve more risk than it's worth when operating on
your files. :)
I think you'd want to pipe the find output via something
like sort if you want a stable sort order. And if you're
piping to sort, then you might as well just use -r to
reverse it rather than add another pipe to tac. E.g.:
$ find . -type d | sort -r
(I'd add '-mindepth 1' as well to exclude the top-level "."
in the output. But I'm not sure if that suits your use-case
here or not.)
