Several issues with this. Here are a few hints:
- The first arg (file handle) for for open is usually bare (no $)
- Your search is made for a plain text file, not binary data.
- Your regular expression is way off (no offence): "\F", "F" and the 16 counts of strings of any length
- 16 FF's would be 'FF' x 16 ... if you were going for a text string rather than binary data
You should review common "regular expressions" and then searching binary data in particular.

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).
