Re^4: How does rename() work on read-only files?

The fact that tchrist's file-dir-perms doc is now relegated to a tarball in the olddoc tree does suggest that it is only kept for historical interest, despite the link from perlfaq5.

Good tidbit hippo! One more question, could you please tell me if that's also a mistake? From file-dir-perms:

What happens when you try to do this?

    perl -i.bak -pe 1 alpha/bar

Well, you seem to think you shouldn't be able to rename it because
it's mode 0555, readonly.  But that's irrelevant.  It's the diretory
that matters.  So it succeeds.

The previous command actually operates on alpha (0755) and on bar (0444). Why did he refer to beta (0555) here?

It's impossible to be certain. I think it is a mistake, but a different one. Given the textual context I think the mistake is just to quote the perms as 0555 instead of 0444. If that one change were to be made then it would make good sense to me. Would you agree?	[reply]
