That works, but I don't like the use of the <> diamond operator to deal with binary files. If there aren't any newline characters in the file, you'll read it all in one go; if there are many of them you'll read a line and print it many times.
I think it's better to use the simple read function for this:
while (read(INP,$buf,8192)) {
print $buf;
}
Much more predictable behavior.
Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
Read Where should I post X? if you're not absolutely sure you're posting in the right place.
