Since $0 isn't anything like "/dev/fd/4" above, you haven't demonstrated that your assumptions apply in the situation described. I'd be quite surprised if they did. You show 3 different ways of getting exactly the same string. When $0 returns "/dev/fd/4", the other two most likely return that exact same string as well.
