Hi.. I wrote a small db manager and I want to corrupt the files to test it, so I wrote this script: 
#!/usr/bin/perl

$fsize = -s $ARGV[0];

open (COR, ">>$ARGV[0]");

for (0..$fsize / 100) {

    seek(COR, rand($fsize), 0);
    print COR chr(rand(256));
};

close(COR);

I want it to seek to a random point on the file, and write a random byte there.. But it's writing all the random bytes at the end of the file, and not in the middle of it..
Am I using the wrong function to seek or write to the file?

Thanks..
