lscpu shows me "op-mode:32-bit, 64-bit", what it means?

Question

lscpu outputs me this information: CPU op-mode(s): 32-bit, 64-bit Does this mean my Ubuntu is running under 32 or 64 bits processor ?

Answer 1

Running lspcu shows you that your processor supports both 32 and 64 bit instructions.

CPU op-mode(s):        32-bit, 64-bit

But this is just about the CPU.

Next, run uname -p

If you see output like this:

x86_64

then you are running a 64 bit OS.

Answer 2

CPU op-mode(s): 32-bit, 64-bit

It means your CPU supports both 32 bit and 64 bit instructions.
