Re^2: 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. Abigail (Conferences and Perlmonks don't mix)	[reply]

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.	[reply]
