A humble question borne of ignorance: Having grown up in rainy climes, it seems plausible that on a drizzly, fully overcast day, Earth would be brighter from space than from the ground. Does cloud cover change anything?

find still gets it right, though:

FreeBSD 13.1. Yes, that case is not as pretty:

As above, charmap is UTF-8. find ééé -name '???' matches it, find ééé -name '??????' does not. But is it a multi-byte character? Hex E9 is still a single byte.

I'm happy to test, if you can create an example of how to create such.

Thank you for providing an example of the bug in GNU find. FWIW, BSD find appears to handle that particular case correctly (CHARSET=UTF-8), matching on -name ????????* but not -name ?????????* and likewise, matching on -not -name '?????????*' but not on -not -name '????????*'.

Also, chmod alone is necessary but not sufficient. The OP also needs to sudo chown root your_script

visudo is the command to fix that.

You might not understand sudo's purpose. It is specifically for use cases like this, when one wants to allow a non-privileged user to run one specific privileged command, without having to enter credentials via an interactive method like keyboard password entry. Read the man page with man sudoers.
