Unfortuantely it appears you're using Windows (a partucular bad
choice for this sort of file processing).  You can, however,
get bash and sed for Windows if you wish:

I would think with the correct RE's you'd only have to call it
once.

As the program runs on progressively more files does the
process's memory usage grow without bounds?  Does the machine
start swapping?
