All you need to know to get started.
The perldoc.perl.org contains the official documentation from the Perl distribution(s). Here are some direct links which may be of interest.
Perl modules come with their own documentation. This includes modules installed from CPAN. On Unix-like (including Linux and Mac OS X) systems, you can access the documentation (for installed modules) with the perldoc
command.
For example, to get the documentation for IO::File, enter
perldoc IO::File
from your command prompt. Module documentation is also available on metacpan.org
Perl FAQs are available as part of your Perl distribution with the
perldoc perlfaq
command. Read FAQs online at http://learn.perl.org/faq/
Perl-related mail lists are archived in several places.
