Find out if your Linux server is running a 32bit or 64bit system

Written by Richi González Monday, 14 February 2011

Hello,

Recently I’ve been working a lot with server setups and stuff like that. I was going to install Ffmpeg and some other modules, and I needed to know the bits of the CPU processor. After looking into various commands I figured out a very simple command that will output exactly what you need.

First, connect to your server via SSH, or if your computer is your server, just open a terminal.

Type in the following:

$ uname -a

You don’t need to have root privileges to execute that command.

My Ubuntu lap returned this:

richi@richi-lap-ubuntu:~$ uname -a
Linux richi-lap-ubuntu 2.6.31-22-generic #70-Ubuntu SMP Wed Dec 1 23:51:13 UTC 2010 i686 GNU/Linux

What we really need from all this output, is the i686, that means 32bit. To make it easier, if instead of i686, was x86_64, then it’d mean you have a 64bit system.

In conclusion anything that is not x86_64, equals to 32bit.

I hope this is helpful! Anything, please leave a comment.

Best Regards,

Richi

    I’ve been exploring for a little for any high quality articles or blog posts on this kind of area . Exploring in Yahoo I at last stumbled upon this site. Reading this information So i am happy to convey that I have a very good uncanny feeling I discovered just what I needed. I most certainly will make sure to do not forget this web site and give it a look on a constant basis.
