If you haven’t, look at the FreeBSD man pages, when possible (most things in coreutils). They are infinitely better than the GNU versions.

I recommend OpenBSD man pages as well.

BTW on Linux, I have "man-all" aliased to "man -a", as I want to read all available man pages (e.g. POSIX, GNU, Linux).
