This is not a good answer, because it tells you whether the KERNEL is 32-bit or 64-bit, but not the userland. The kernel could be 64-bit with the userland being 32-bit. That is a supported configuration. The original "file /bin/true" (I've always preferred "file /bin/ls" myself, since /bin/true has at many times been a shell script) is a much better answer.
