How do I use $File::Find::prune?

If you don't want to recurse, you probably want to use glob.

If you want to filter the subdirectories recursed into by File::Find, you should use the preprocess function (not the $File::Find::prune variable) as this gives you much more control. The idea is to provide a function which is called once per directory, and is passed a list of files and subdirectories; the return value is the filtered list to pass to the wanted function, and (for subdirectories) to recurse into.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
