Why are you building "diff" capability into dlstat? Why aren't the various incarnations of diff suitable for use here? Isn't it better to provide output that is friendly to diff(1) use? My assertion is that if the output is friendly to diff(1), then you don't need to build in diff capability and that the output will also then be friendly to many other commands. Darren
