To find if cpu is 32bit or 64 bit in linux

Here are two ways of finding out,using linux, whether a processor on a system is 32bit or 64 bit.

1. Using proc entry.

Run the command

The above output clearly indicates that the address size of the cpu is 32 bits and hence does not support 64 bit.

2. Using the command cpuid.

For this we will have to install the package cpuid

After the installation run the command

From the above output too we can conclude that the cpu is a 32bit architecture.
