determine if you have a 64bit processor

Question

I would like to find out on the console if my processor is 64 bit capable.

I can find out that I have installed the 32 bit version of Ubuntu with

uname -a

If it doesn't contain 64 at all, then I know I have a 32 bit kernel.

But how can I find out if I could install the 64 bit version as well?

Answer 1

You can either run

lscpu

or

cat /proc/cpuinfo

The most definative way would probably be to run:

lscpu | grep op-mode

That will give you a nice 1 line return.
