I find that command five runs three times.

If your perl code is structured like that pseudo code, "command five" will only run once. Unfortunately, there's no way for us to tell what the problem is with your actual code because you didn't provide it.

You'll probably get the help you need if you show us your real code. The response will also be quicker and easier on the editors if you wrap it in <code></code> tags.
