The problem is, you can have a 64-bit kernel and a 32-bit userspace.
So, there's no "uname" command that answers the real question.

The real command the OP is looking for is dpkg --print-architecture

I still prefer file /bin/ls because I can *remember* it (and it'll work
on non-Debian-based systems).
