Easiest way to find out if you have a 32-bit or a 64-bit OS

I need to install an app but, like in many cases, I need to find out if my Zorin OS is a 32-bit or a 64-bit. I used to know but I have forgotten. So what do you do if you are in my situation? Here is how I did.

Firstly, I did a google search and find out on a quite similar question on Ask Ubuntu forum. By the time I am writing this blog post, there are already 12 answers. But to be frank, none of them appeals me. I didn’t wont complicated and sophisticated operations and I certainly don't wont to install an app just to find out if I can install a certain app. It already sounds crazy.

No, I just want something quick, simple and clean. And a terminal command line is the answer. I have found it thanks to a fellow chatter from the Ubuntu & Linux chat.

So, here it is:

Open Terminal (Ctrl+Alt+T) and write the following line exactelly as it is:
getconf LONG_BIT
And then press Enter

The needed result appears instantly.

Here is it how it looks in my Terminal window.
