Just to add to what ikegami said, File::ReadBackwards will not only read the file line by line, starting at the end of the file and working backwards, but it will read record by record (which usually is line by line, but doesn't have to be). This is a pretty flexible solution. In fact, unlike the plain old <> operator, File::ReadBackwards allows you to set the record separator based on either literal text, or a regular expression. Nice!

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).
