Seeking the wisdom of my fellow brethren

I have a script that does some automatic analysis from Windows perfmon logs. What I want to do is use the standard windoze relog.exe utility to do some merging/filtering/conversion to csv.

I can get it to run fine by doing an open with a pipe and that returns most of the output (via STDOUT and STDERR).

However what the relog command does is write its progress as an increasing percentage figure. I'd like to capture this - the logs I'm relogging are big and take some time to complete.

Any thoughts on this? I've seen other programs do this and have wondered how we can capture this sort of info.
