in reply to New User .. Need help with some tutorials or books
Another thing that really helped me was to locate where the CPAN library modules on your system are located, open up a (read-only!) editor or browser, and skim through the code. I prefer to learn by example. (And the operative word here is skim. You won’t understand everything you have seen, but you will have seen it.) I think that this will be an important adjunct to the books, perldoc topics and other sources previously mentioned.
You can find the locations by entering perl -V with an upper-case “V” and looking through the (rather voluminous) output.
