Why did you specify the -maxdepth switch after the argument without the -type switch, and the keys are not positional (-maxdepth affects the tests specified as before?

Question

linux

I'm trying to run a query:

find /home/book/book.ru/uploads/compress -type d -maxdepth 3 -mindepth 3

As a result, I get an error:
warning: you specified the -maxdepth key after the argument without the -type key, and the keys are not positional (-maxdepth affects the tests specified both before and after it). Specify keys before other arguments.
I figured out what to do:

find /home/book/book.ru/uploads/compress -maxdepth 3 -mindepth 3 -type d

But why the error?

Answer 1

This is not an error but a warning. Warns that other versions of find that adhere to the standard may consider this a bug. Portability concerns.
