If we're going as far as having access to "cat" and "shell", then it might be fun to tinker with "dd" as well. Then the OP can get to just the part of the file he wants to:
open(THIRDMB, "dd if=$filename bs=1024 skip=2048 count=1024|") or die;
while(<>) { ... } # Reads third MB of file only.
close(THIRDMB);
dd's useful in Unix for skipping around in large files at the shell level where seek(2) might be a bit more complicated.

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).
