Find Architecture of Centos/RHEL/Fedora- x64 or x86 installed?

This is a VERY simple command. I recently had a server that was installed and I had forgotten if it was x64 or x32. This is a super simple way to tell what architecture you have installed.

Simple command will let you know what you installed last month while half asleep at 2am.
