One Command to Check 32-bit or 64-bit Ubuntu you Installed

Last updated: July 3, 2013

3-bit or 64-bit? If you forgot which version you installed, here’s how to check it out!

In command line, just type this:

uname -m

Then you see the output:

  • i686 means 32-bit
  • x86_64 means 64-bit

If you’d like a GUI way, searh for and open details from Unity Dash.

System-details

Then you’ll see the result

system-details2

Enjoy!
