The correct way to resolve this issue and as many Mono-related issues, and how to deal with differences in behavior across different operating systems (for example, the Ping class is a real pain), you should probably use the ProcessStartInfo class and do the parsing.
IMHO, this is a real solution that requires a lot of work (remember that sometimes console commands are localized = /) to make it truly "platform independent". Ironically, you will have to make a great platform to work to achieve your goals, but in any case, it can be a way to achieve your goal.
