> On Illumos the "file" command is 32bit (as the kernel can run both 32 and
64 bit happily together), on Linux the above command is a sensible way of
working out what bit kernel you're running as it's more of a PITA to run
32bit and 64 bit side by side (or so I believe) ...

On Linux:

jadams at EID-4546:~$ file `which file`
/usr/bin/file: ELF 64-bit LSB executable, x86-64, version 1 (SYSV),
dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux
2.6.32, BuildID[sha1]=ecc4d67cf433d0682a5b7f3a08befc45e7d18057, stripped
