Quick note: perldoc -q regex will
use a regular expression to perform a search of the
perlfaq pages you mentioned. For instance:
[cwinters@genesee cwinters]$ perldoc -q hash
Found in /usr/local/lib/perl5/5.6.1/pod/perlfaq3.pod
How can I free an array or hash so my program shrinks?
...
Found in /usr/local/lib/perl5/5.6.1/pod/perlfaq4.pod
How do I test whether two arrays or hashes are equal?
...
Data: Hashes (Associative Arrays)
How do I process an entire hash?
...
What happens if I add or remove keys from a hash while
iterating over it?
...
How can I always keep my hash sorted?
...
What's the difference between "delete" and "undef" with
hashes?
...
How do I sort a hash (optionally by value instead of key)?
(etc.)
Not only is this useful in and of itself, but since the
FAQ entries frequently contain references to other perldoc
pages folks might not know about
(perlbot, perlref, ...), it's
a great starting point, too.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
