4.2 Perl Documentation
A wealth of information is available for Perl both on your Linux machine and online. There are several man pages:
$ man perl
$ man perlop
$ man perlsyn
A program called perldoc:
$ perldoc perldoc
$ perldoc -f print
And a Web site: www.perldoc.com/. There are also newsgroups, CPAN at www.perl.com and big, fat Perl books, should these not suffice.
