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

```

Answer: 
Your kernel is a i686 version, so 32 bits.
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
