you can consider Pragramming Perl 4th edition as alternative to Beginning and Intermediate Perl book serie, but i dunno which can be more digerible digestible (thanks erix!) for you.

Modern Perl is the best fresh look to basic and some advanced topic and is also very concise.

If you have so few hours i suggest to spend some to investigate what happened outside the mere language itself and in this perspective Task::Kensho is formidable: is a collection of very selected modules from CPAN that are the state of the art in many fields.

Perlmonks, for sure, is full of interesting things and questions from very experienced monks and others lurking and learning like me, so write code and ask.
