The OP copied the lines for the open calls that I provided -- but skipped the rest of the script. Granted I missed the check on the readdir, but I also noted that (and at least failure there would just mean that @files would be empty, rather than trying to alter files in the wrong directory).
I had hoped that the OP would see what was intended with the advice given, but I think that's too much to ask. I was toying with the idea of completely revising the script (I have a current script that's taking a very long time to execute, so have some downtime while I wait for it) but I think it would be rather pointless.

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).
