How to Verify if Linux System is 32-bit or 64-bit?

You will find the 64-bit OS in most modern computers. It is always recommended to have a 64-bit OS for Linux as you can have good performance and better security. If your system is running with an old 32-bit processor, in that case, you will need to install the 32-bit OS. 

There might be a case when installing any software or an application that requires you to check whether the OS is 32-bit or 64-bit. For this, you can use your machine terminal and run the below command to verify it –  


The architecture option shows x86_64, which means your system runs on a 64-bit CPU. On the other hand, if you find x86_32, it means your system is running on a 32-bit CPU.

If the CPU op-mode(s) option shows - 32-bit, 64-bit - your system runs on a 64-bit Linux OS distribution. If you see only 32-bit, your system runs on a 32-bit Linux OS distribution.
