Thank you,

my idea was similar, I was thinking about using ls and cut and perhaps something else and then compare both trees (files) using meld, since meld seems to be smarter regarding files that are just in one of both trees (files), than diff is. Sometimes diff becomes unreadable.

Maybe or maybe not, since I never used Perl. It's likely to risky.

I didn't take a look at the links yet, but I will do so soon.
