dear monks, This is either going to be very easy or very hard (I think). Let me try to explain: I am writing a little script that fetches pages from the www like many of us problebly have done. I'd like to include a little progress indicator, which is not very hard when you can read the 'content-length' http header. My code looks like this: 
while ($total < $length) {
    $read = read($remote, $buffer, int($length/100));
    $stuff .= $buffer;
    $total += $read;
    $done = sprintf("%.2f", $total/($length/100));

    print "$done%\n";
}

This works just fine. It's only that every loop the progress is printed on a new line (in the console). Much nicer would be if it would stay on the same place all the time. I hope you know what I mean. I think I saw the CPAN shell do this. Many console applications do this too, like rpm. Thanks very much.

In reply to printing in a specific area of the console by io
