64 bit or 32 bit

Post by jult » 2007/05/21 09:43:55

Hi

I need to know which version of CentOS is installed on my system. I only see:

# cat /etc/redhat-release
CentOS release 4.5 (Final)

# cat /proc/version
Linux version 2.6.9-023stab033.6-entnosplit (root@rhel4-32) (gcc version 3.4.5 20051201 (Red Hat 3.4.5-2)) #1 SMP Tue Nov 7 16:30:45 MSK 2006

but this does not tell me if it is

alpha i386 ia64 s390 s390x or x86_64

(where I need to get and install packages from..)

I.e. is this a 64 bit architecture system, and if so, which version?
How do I find out?

Never mind, I found out that i686 is one of the i386 releases.
