In POSIX -R is the recursion flag for ls, cp, rm, etc. So if you want to recurse, -R is probably a safer bet than -r. (ls -r just lists in reverse.)

Yeah, that may be it.. I'm wondering why they didn't just add a new option (aka --no-symlinks) or something

Annoying exception: scp only accepts -r as recursion flag, not -R.

Same here. I've been conditioned to use -R

Good point. Also, since you reminded me, chmod, chown, chgrp.

that's probably it
