How do I find out what other groups have write permissions on a folder?

Question

When I

ls -la

I get a folder that has a green background and blue text. My googling tells me this means its 'other writable'.

I think this means another group has write permission to this folder.

How do I find out what other groups have write permissions on that folder?

Answer 1

No particular group. That's just literally everyone else. If you don't want this, set it to 4 (read-only) or 0 (nothing).
