Chris Rees writes: sysctl hw.machine_arch It and uname -m work beautifully. Thanks to all. One thing I discovered while trying this command out on various systems is that if the system was originally built using i386 code, it reports as i386 even though there is a 64-bit platform struggling to get out. In my script, this is not a problem because the mfsboot CDROM for 32-bit boxes chokes on a 64-bit platform and will not boot. When on a 64-bit system, it boots like gang busters and since it installs its own OS, there is no question at all. Thank you all. Martin McCormick
