Yup, it tries to guide you to opsol-help (the forum/mailing list) where you can post as many help requests as you want. Enough for constructive, helpful trolling. Back to your question: The 2 is the descriptor for the error output (stderr). The > is redirecting all things to the following channel or file. The /dev/null is a device which is something like a black hole in your unix system. So, every error message is redirected into nothing.
