After some coersion, your response led me down the proper path. Here's my updated code snippet:
my $match = pack 'H*',
'53005f00560045005200530049004f004e005f004' .
'9004e0046004f0000000000bd04effe00000100';
open(FILE,$file) or die $!;
while (<FILE>) {
if (/$match(\S{2})(\S{2})(\S{2})(\S{2})/) {
print "Found match!";
print join('.',map {unpack 'H*',$_; } ($1,$2,$3,$4);
}
}
close(FILE);
I think my confusion rested in how perl would handle a binary file. Seems that the DWIM held true... I was making it harder than it was.
Thanks for your help!
Cheers,
Shendal

Are you posting in the right place? Check out Where do I post X? to know for sure.

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).
