Indeed, there is a module called File::ReadBackwards available
through CPAN. From the description in the man file:
This module reads a file backwards line by line.
It is simple to use, memory efficient and fast.
It supports both an object and a tied handle interface.
It is intended for processing log and other similar text
files which typically have their newest entries appended
to them. By default files are assumed to be plain text and
have a line ending appropriate to the OS. But you can set
the input record separator string on a per file basis.
Autark.

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).
