Re: [ubuntu-uk] uname -a for 32 bit os on 64 bit cpu
I find running uname -m is easier for determining whether it's a 64 bit machine or not. Generally though, you just need to look out for x86_64 which is on a 64 bit machine, and i686 or similar for 32 bit.

What does uname -a produce for a 32 bit operating system running on a 64 bit cpu? uname reports information about the kernel, not the hardware. So for a 32-bit kernel it will report 32-bit information (with strings like i386 and i686), and on a 64-bit kernel it will contain 64-bit sorts of strings (x86_64, amd64 etc.) Precisely what it says depends upon what the person who built the kernel told it to, though. -- Avi -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.ubuntu.com/UKTeam/

Thanks to everyone who replied. Does seem that uname reports the kernel, and not the hardware, which is what is suggested by the man page and http://ss64.com/bash/uname.html My bit of documentation, on installing the beta of Zotero, is now published: http://anterotesis.com/wordpress/2011/11/installing-zotero-standalone-on-ubuntu-11-10/ Comments, clarifications etc welcome.

TL;DR: it doesn't matter what is your hardware, the important it's which kernel are your running. It's not a big deal, although the words aren't 100% accurate. If you're running a 32bits kernel, it doesn't matter you have 64bits hardware. Besides that if you're running a 64bits kernel, it's probably a good idea you run the 64bits version of any application; but you can still run the 32bits version (although it may involve installing more 32bits stuff, such as shared libraries).
