in reply to Dynamically printing out iteration number from foreach loop

This is happening because the output is being buffered. You can turn on the auto-flush for the buffer by adding the following somewhere in your script before what you want to be unbuffered:

$| = 1;

$| = 0; reverts everything back to normal. If you want to get more complicated, you can try IO::Handle, but it is probably overkill for what you need.
