32-bit or 64-bit

Is there a command that will tell me if the operating system is running in 32-bit mode or 64-bit, or the version installed .....

(like `uname` returns the platform type)

"uname -r" returns the "release" of the Operating System. On HP-UX, I get B.11.11. With SunOS, I get "5.8". That's close enough to be usuable. So this is an answer to the 2nd part of of question.

As for the first part, HP-UX has a command "getconf KERNEL_BITS" that will do exacyly what you want. Sun's getconf does not have this feature though.

I also know that in HPUX you can run "swlist |grep 64 " and get this output.


# swlist |grep 64

HPUXBase64 B.11.11 HP-UX 64-bit Base OS

In your flavor, list patches and grep for 64.

On Solaris 7 and above, you can use the isainfo command.

% isainfo -kv

According to AIX pages at IBM, the /etc/inittab is altered to load the 64-bit kernel. You might be able to tell from that.

IBM AIX BOS 64-bit
