"I've looked at open and..."
"Please tell newbies to die to always include the $! at the end. If I had $! at the end of my die message, it would have cut at least 15 minutes of me traversing directories thinking the file did not exist."
Not sure how you missed this, it's in the open documentation, all the examples and you have been told about using this before (e.g. Creating a random generator). Also, consider avoiding File::Slurp due to issues.

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).

or How to display code and escape characters
