Hello CalebH,
I’m glad seek was helpful! As to the rest: when I said “more expensive” I was thinking of CPU usage only, not memory usage. Sorry I wasn’t clearer. If memory is tight, it’s obviously more economical of memory to read the file progressively than to keep it all in memory at one time. And if that means reading the same file more than once, that may just be the price you have to pay to keep memory usage within acceptable bounds. But it seems your new version avoids that problem anyway.
Cheers,

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).
