I was unable to connect to that site, but check this one out:
http://unix.about.com
It's a little hard to navigate; check the left hand column.
History, tricks, tips, etc...
A good website, even if not layed out very well.
[Note: It's been a long time since I've been there, and in reviewing this, I noticed that there are lots of ads, and multiple pop-unders for each page visited... Yuck!]

Devel::REPL::Plugin::OutputCache(3pm) User Contributed Perl Documentation Devel::REPL::Plugin::OutputCache(3pm)
NAME
Devel::REPL::Plugin::OutputCache - remember past results, _ is most recent
SYNOPSIS
> 21 / 7
3
> _ * _
9
> sub { die "later" }
sub { die "later" }
> _->()
Runtime error: later
DESCRIPTION
Re-using results is very useful when working in a REPL. With "OutputCache" you get "_", which holds the past result. The benefit is that
you can build up your result instead of having to type it in all at once, or store it in intermediate variables. "OutputCache" also
provides "$_REPL->output_cache", an array reference of all results in this session.
Devel::REPL already has a similar plugin, Devel::REPL::Plugin::History. There are some key differences though:
Input vs Output
"History" remembers input. "OutputCache" remembers output.
Munging vs Pure Perl
"History" performs regular expressions on your input. "OutputCache" provides the "_" sub as a hook to get the most recent result, and
"$_REPL->output_cache" for any other results.
Principle of Least Surprise
"History" will replace exclamation points in any part of the input. This is problematic if you accidentally include one in a string, or
in a "not" expression. "OutputCache" uses a regular (if oddly named) subroutine so Perl does the parsing -- no surprises.
CAVEATS
The "_" sub is shared across all packages. This means that if a module is using the "_" sub, then there is a conflict and you should not
use this plugin. For example, Jifty uses the "_" sub for localization. Jifty is the only known user.
