Command to know if OS is 32 or 64 bit

[Harishs]

Hi,
Could you please let me know the command on HP UX 11.23 to know if OS is 32 or 64 bit.

Many Thanks

Harish

Hi Harish,

# file /stand/vmunix

/stand/vmunix: ELF-64 executable object file - PA-RISC 2.0 (LP64)

getconf KERNEL_BITS

getconfHW_32_64_CAPABLE will tell you if the hardware is capable of 64 bits.

Hi:

# getconf HW_CPU_SUPP_BITS

...will show what you *can* run, whereas

# getconf KERNEL_BITS

...shows what you *are* running.

Regards!

Many Many Thanks !!!

It solved my purpose.

Actually, 11.23 is always a 64-bit kernel. There is no 32-bit 11.23 kernel.

A 64-bit kernel can run both 64 bit and 32-bit applications.

The getconf KERNEL_BITS is still the "right" way to go of course, but I thought I'd point-out that bit of trivia.

Another bit of trivia is that *any* HP-UX 11.X kernel on a PA-8500 or later CPU - including Itanium - is always a 64-bit kernel. The only time an 11.X kernel might be 32-bit is when the CPU is PA-8200 or earlier.
