how to find out whether os is 32bit or 64 bit

[deep_tkt]

Hi all,
I want know how to find out whether os is 32bit or 64 bit by using Unix command.

i am using HP-UX B.11.23 U 9000/800 1462123939 unlimited-user license

Regards,
Deep

Hi Deep,

Good day to you !
For your system, I believe its running on 64 bits. And here is the command to confirm that one :

# getconf KERNEL_BITS

It will return 32 or 64, which indicates 32-bit or 64-bit HP-UX

Hope this information can help.

Cheers,
AW

and even on the Merijn's FAQ page:

From my notes:
getconf KERNEL_BITS â what version is running
getconf HW_CPU_SUPP_BITS â what version CAN be run

$ file /stand/vmunix
/stand/vmunix: PA-RISC1.1 executable ---> 32-bit
/stand/vmunix: ELF-64 executable object file ---> 64-bit

Hi,
Oneline reply - use "getconf KERNEL_BITS"

the "KERNEL_BITS" bit is the "proper" way to go. those fond of trivia can note that _all_ 11.23 kernels are 64-bit kernels, and that for OSrev >= 110 on PA, only the PA-8200 and earlier CPUs "supported" a 32-bit kernel. PA-8500 and later CPUs are 64-bit kernels only. ditto for Itanium - all HP-UX kernels on Itanium hardware are 64-bit kernels.
