Current Perl documentation can be found at perldoc.perl.org.
Here is our local, out-dated (pre-5.6) version:
Have you looked at CPAN (see the perlfaq2 manpage)? The chances are that someone has already written a module that can solve your problem. Have you read the appropriate man pages? Here's a brief index:
Basics perldata, perlman:perlvar, perlman:perlsyn, perlman:perlop, perlman:perlsub Execution perlrun, perlman:perldebug Functions perlfunc Objects perlref, perlman:perlmod, perlman:perlobj, perlman:perltie Data Structures perlref, perlman:perllol, perlman:perldsc Modules perlmod, perlman:perlmodlib, perlman:perlsub Regexps perlre, perlfunc, perlman:perlop, perlman:perllocale Moving to perl5 perltrap, perl Linking w/C perlxstut, perlman:perlxs, perlman:perlcall, perlman:perlguts, perlman:perlembed Various http://www.perl.com/CPAN/doc/FMTEYEWTK/index.html (not a man-page but still useful)
the perltoc manpage provides a crude table of contents for the perl man page set.
