How to Check if Your Ubuntu Server is a 32 bit or 64 bit Installation Software & Sites 13 APR 2012

Because you don’t want to waste time and bandwidth by accidentally downloading the wrong bit version of your operating system, it is pretty useful to know whether or not your server is currently using a 32 bit or 64 bit version.

To check this via the terminal, run:

uname -m

Its output can be interpreted as follows:

x86_64 = 64 bit
i686 = 32 bit
i386 = 32 bit
