JbinUp up will auto make an nzb after the post is uploaded if you choose it to. The only binary command line poster I know of is 'Newspost'
http://newspost.unixcab.org/
Mainly I use Sabnzbd+ but I also use pan for header grabs from a few smaller groups and JbinUp to post binary. Never really posted just text so no experience with that.
EDIT:
Seeing as you are a Debian user, I think (not 100% sure though) that this tutorial for newspost under Ubuntu will help you get things going somewhat simply.
