uname -a works on Linux, as others have said, but I am not certain
what it shows on a Darwin type (mac OS) machine. But are not all
versions of OS X i386 no matter what the architecture is (other than,
or course, the power PC stuff)? In other words, no 64-bit version,
right?

cat /proc/cpuinfo will tell you if a box can support 64-bit, but it
won't indicate if a particular installation is 64-bit, of course, and
likely doesn't exist on OS X.
