Aha! I didn't get that you meant the issue was accidentally using -r instead of -R since both you and OP wrote the upper case one.

I'm a lot more used to -R so I instead get caught off by commands where that means something other than recursive :)

I mostly use symbolic mode and honestly don't get why everyone else seems to use octal all the time.

People probably confuse it with tools like cp, rm, ls, etc as they use -r for file recursion.

[–] kattfisk@lemmy.dbzer0.com 2 points 8 months ago

ls -r actually lists entries in reverse order! It needs -R as well.

cp and rm accept either.

Looking at some man pages the only commands I found where -R didn't work were scp and gzip where it doesn't do anything, and rsync where it's "use relative path names".

(Caveat: BSD utils might be different, who knows what those devils get up to!)
