in thread A DWIM too far?

Note that if you want to do a "safe" rename, you can do so, although it involves a copy

I may have missed something, but I think it can be done much more easily like this:

sub rename_i { my($src, $dest) = @_; link($src, $dest) or die "Can't link $src to $dest: $!"; unlink($src) or die "Can't unlink $src: $!"; }

    Well, yes, of course. And I should have know, because that's classical idiom. I'm just going to blame YAPC. 12 hours of sleep in 3 nights.

    That may not work for directories.

    But I think that idiom justifies Unix's choice of rename behavior. If rename failed when a new file already exists, there isn't good way to code a rename-that-overwrites.
