What's the command to find out which Debian package architecture I'm using?

eg, on a 64 bit x86, I'm expecting something like amd64, i386 on 32 bit x86 and darwin-x86_64 from OSX 10.6 (via Fink).

dpkg-architecture is in the dpkg-dev package which isn't installed by default (although it is a dependency of build-essential). However, dpkg is by definition guaranteed to be there. – Neil Mayhew Feb 26 '13 at 18:15
    
@NeilMayhew good call, switched my accepted answer – therefromhere Feb 26 '13 at 21:29

In case you did add some other architecture that you forgot, like i386 to an amd64 system, you can check it by:

dpkg --print-foreign-architectures
