Originally, I had the program open the file in the manner that you have coded (Once only) however the amount of data in question is massive. This caused the program to use up all the memory of the server I am using, and the OS would randomly kill the program in favor of OS processes. I, perhaps incorrectly, favored the line by line approach because on runtime, the program only uses 0.3% of the RAM, instead of 100%. Perhaps it might be worthwhile to break up the files into chunks and read in maybe 100,000 or so lines at a time?

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).
