Watching the video, in pieces as it downloads enough to play, I see he uses File::Copy to copy an executable file and it doesn't execute.

That sounds like something odd about the implementation of File::Copy on *Nix, or the underlying file copying OS call it defers to. On Windows, the copy file OS function copies everything including security streams. On the other hand, there is no 'cp' on Windows, so calling system cp won't work either.

So I don't like his final quote about people who don't understand unix tend to reinvent it badly. Instead, people who don't know unix write native file copy API's that work sensibly in the first place.

What I want is a function to copy a file (or directory) that works robustly and has implementations for all platforms. He's arguing that File::Copy isn't it.
