Printing process of program

k2 has asked for the wisdom of the Perl Monks concerning the following question:

Hi!
I'm writing a program that will handle huge textfiles and in order to see the progress I wrote this bit of code that prints the procentage of the file that has been delt with and on witch line in the text the program is on.
But it's not working out the way I was expecting.
It works fine on small text-files, but when I run it on files that are 2-3 Gb the procentage-counter counts from -0% to aprox. -115% and then stops while the part that prints the line the program is on keeps running...

Anyone got any ideas?

This might have been up to discussion earlier, if so please point me in the right direction.

Regards k2
-------------------

$fs = (-s "@ARGV" );
$rowcount=0;

while () {


    Run whatever loop you want...


if  ($rowcount % 1000 == 0 ) {
        print "\r", int((tell INDATA) /$fs*100), "% done = $rowcount r
+ows ";}
    $rowcount++;
}

See the node on processing large files. I think the problem is the `tell` on files > 2G. Can you use some other technique to show progress, i.e. by counting rows, or accumulating how many bytes you've read, rather then using `tell`?	[reply]

Could be a problem with large file support on your platform. What was your platform, sir? Try printing out the value of $fs and (tell INDATA), and see if those look reasonable.	[reply]

Sorry, should have included my OS. This is running on a w2k-machine. I guessed there might be a problem with the large files, just wanted to know if anybody else were having this problem. I have compared the values on smaller files and they look ok but I have to get a better editor in order to check these large files... Thanks k2	[reply]
