Aside from learn.perl.org which is under-maintained and incomplete, I've been maintaining an alternative Perl beginners site on http://perl-begin.org/ , which is much better.

We're covering file manipulation, string manipulation and hash tables extensively on the various resources of http://perl-begin.org/ . However, often newcomers come with unique problems which require understanding of the programming primitives provided by Perl and how to combine them to produce a greater solution. This is something that cannot be taught from examples, and if you desire examples you can look at: http://rosettacode.org/ > And I would want to > see codes from experts here once in a while with their design's reasons. What kind of codes from experts? Experts here often give code as answer to questions.
