BTW, you shouldn't use <$file> and print if you are just copying the file. Especially if the file is a binary file. You set binmode which is good so it won't change end-of-line characters. But copying line-by-line is slower because the input must be scanned for end-of-line characters. If you just want to copy the file, use read and print with a fixed buffer size as large as you can get away with.
while ($bytesread=read($filename,$buffer,1024)) {
print OUTFILE $buffer;
}
(Code is from the CGI man page).

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).
