in reply to Deleting hash entry

    What happen if I do: delete($hash{abc}{def});

I would hazard a guess that the hash key value pair you have specified would be deleted. What happens when you try it? (I did not.)

    .. is there a short way to delete also the first level key ('abc' in the example) when deleted all second level keys under it.

Sure, I would use delete($hash{abc})
This would delete the top level and everything underneath it.

And now, an editorial comment ..

Please, I would strongly urge you (and anyone else) to go into the Perl debugger and try these things out rather than posting here. Wait until you've tried a bunch of things and are well and truly stumped. We love interesting, challenging questions. Questions that show no effort leave us uninspired.

    Should cpanminus be part of the standard Perl release?
