When I have a perl script chugging away at a large amount of data, I'd like more visual feedback than a blinking hdd light.

I've tried to make a simple progress indicator that just adds a dot while it's working:

..................................

but it doesn't seem to actually get sent to stdout until I send "\n". Is there a way around this?



Relevant system info:

running perl in a dos window

This is probably due to output buffering. Put a line like this:
$| = 1;

in your code.

See this:

for an explanation of what's going on.
