Are You Using 32 bit or 64 bit Ubuntu?

We are getting a ton of Ubuntu newbies stumbling in here so I'll be posting useful tips that pro users might already know. 

From time to time you will want to know what processor you are running. Maybe you've just bought a new computer or working on a friends and no one has a clue what the processor is inside. An easy terminal command will give you the info.

Open up a terminal by going to Applications > Accessories > Terminal and type:

uname -m

This will tell you if you have a 32 bit system or 64 bit system. If it says i686 then you have a 32 bit, if it says x86_64 then you've got a 64 bit. You can also find out a little more info like the kernel you are using by typing in:

uname -a

Another simple terminal command I like to use which gives basic version info of the release you have. try this...

lsb_release -a

You will get some output like this:

Distributor ID: Ubuntu
Description: Ubuntu 10.10
Release: 10.10
Codename: maverick

Hope it helps!
