I wouldn't say that PERL is my first and favorite language, but I would say that I have grown to appreciate it. I find that everyone has a different style when writing code in it. It is powerful with a lot of available CPAN modules, this makes development bit easier. I've seen some pretty amazing scripts...and some pretty unreadable perl code. So it goes. The Perl motto TMTOWTDI, "There's More Than One Way To Do It" ,pronounced "tim toady". Is no myth in Perl. blogs.perl.org - blogging the onion Perl Mongers - Perl User Groups.

A nice function reference: Perl Programming/Function Reference - Wikibooks, collection of open-content textbooks Many times when you write PERL code, you want to use modules. These modules usually reside on the CPAN sites (The CPAN Search Site - search.cpan.org). To install them, find the module, download and install. One nice utility I've found is the CPAN management shell. Just run: perl -MCPAN -e shell;Then when you are inside the shell type: install <module> (which could be something like MODULE::Name) This will automatically download, unpack, and install the app. It will also grab any deps. that are needed when installing! Very nice indeed. :) For more information about it, search for: CPAN on the CPAN search. Here's a single liner to install a module from the CLI. perl -MCPAN -e 'install MODULE::ToInstall'Also, if you for some reason need to reconfigure your CPAN options: useful.things » Blog Archive » Perl CPAN reconfiguration App::cpanminus - search.cpan.org - App::cpanminus - get, unpack, build and install modules from CPAN Some really great PERL tutorials live here: Alex Batko :: Programming :: Perl Sam Graham's website > Perlblog Introduction to References How do I print a hash that has a hash within it? CPAN wrong directoryI have had issues in the past when uninstalling and installing perl on machines with cpan using the wrong directory. If you find yourself with the same issue, try checking for a MyConfig.pm in your local directory. In windows, I found it in "Local Settings\Application Data\.cpan\CPAN\MyConfig.pm"Nice way to start your perl file#!/usr/bin/perl -Tw # force taint checks, and print warnings use strict; # install all three strictures use warnings; # print warnings $|++; # force auto flush of output buffer dos2unix/unix2dos in perlperl -pi -e 's/\r\n/\n/;' *.ext #dos2unix perl -pi -e 's/\n/\r\n/;' *.ext #unix2dos teideal glic deisbhéalach » Blog Archive » Peruse popular Perl packages Perl version 5.10.0 documentation - perldoc.perl.org - where to go for docs on perl.

Try out the following:my @array = undef; if(@array) { print "defined\n"; } else { print "undefined\n"; }You will find that you get a defined value back! So when you return an array, returning undef does not make the returning @array undef. Instead, use the empty array ().
