32Bit or 64bit?

astrotrain1 · 06-26-2006, 12:32 PM

I have Red Hat installed on a few boxes, and I was wondering if there is a easy way to tell if I am running 32Bit or 64Bit.

Thanks.

^^^^^^^
At least that will tell you what type of kernel.

uname -i, should show you whether redhat is i386 or x64.

Here is what I have for one box:

Linux 2.4.18-3 #1 Thu Apr 18 07:37:53 EDT 2002 i686 unknown

i686 would be pentium class but uncertain if it is 32Bit or 64Bit.

your linux is 32bit thats for sure
because its a 2002 kernel.

the -i option does exist on my FC5.

Thanks now just need to verify another ten boxes.

What version of the Kernal was first offered in 64bit as well?

Thanks
