How to find if my Amazon EC2 instance is 32 bit or 64 bit?

I am newbie to this and this may be very easy question but I am running a Amazon EC2 instance and I don't know if my running instance is 32 bit or 64 bit.

My Question

Is there any way to find if my instance is 32 bit or 64 bit?

Solution

  • This should work for any linux instance. On the terminal type the following command:

    > uname -a
Linux domU-XX-XX-XX-XX-XX-XX 3.2.20-1.29.6.amzn1.i686 
      #1 SMP Tue Jun 12 01:20:33 UTC 2012 i686 i686 i386 GNU/Linux

    That last "i386" indicates that it's 32-bit; "x86_64" indicates 64-bit.
