The 1st link on my homepage on my work's intranet has the following title: "What every perl user at <my company> should know about Perl".

Disclaimer: my co-workers and I are not programmers; we are hardware (chip) designers. However, many of us use Perl regularly to make our lives easier in a unix setting.

From memory, here is the condensed list:

• Every Perl script must have this exact shebang line: #!/usr/bin/env perl
• Every Perl file (script and module) must have use warnings; use strict; near the top
• Perl documentation is available online at Perl documentation and at the command prompt, for example perldoc -f split
• A link to CPAN.
• To get help, use google, and for a more focussed search use PerlMonks' Super Search
• Debug with print and Data::Dumper
• To help understand someone else's ugly code, run it through perltidy
• Check your code for potential issues using: perlcritic -1 my_script.pl
• You can test your Perl code using Perl: Test::More
