How many bits in my Ubuntu?

Question

How can I find 32 or 64 bit my OS is? I thought uname returns it, but I can't find it there.

> uname -a
> Linux fl00r 2.6.35-27-generic-pae #48-Ubuntu SMP Tue Feb 22 21:46:58 UTC 2011 i686 GNU/Linux

This is a question for [Super User](http://superuser.com/), where it's already been answered many times, for example [here](http://superuser.com/questions/208301/linux-command-to-return-number-of-bits-32-or-64). — Gilles 'SO- stop being evil', Mar 18 '11 at 01:06

Your kernel is a i686 version, so 32 bits.

i386 and i686 is 32 bit? and which kernels are for 64? – fl00r Mar 17 '11 at 10:32
Yes, they are. 64 bits kernels are for example, amd64 or ia64. – Laurent Nominé Mar 17 '11 at 10:42

64bit may also be written as x86_64 which might cause some confusion. – chunkyb2002 Mar 17 '11 at 10:51

Something not quite on the question but something u might find useful,

more /etc/issue

tells u about the OS on nearly all *nix boxes.

Also check out: /proc

ie: more /proc/version

Hope it helps
