    Sorry but I don't get it.

    First, after a perldoc on the glob, I get totally lost, I never touch a Unix shell, so I couldn't imagine or relate to anything.. I am on Win32 all time..

    Second, would you explain more for what is your code try to demonstrate? Is this a safe/suggested way to do what I want? or it's proving my way is danger? or anything else ?

      Second, would you explain more for what is your code try to demonstrate?
