How do I find out If Running Kernel Is 32 Or 64 Bit?

Target Audience: Beginners of Linux/Unix Users

Many beginners of Linux/Unix users might struggle or uncertain when they download softwares for Linux/Unix to choose correct software according to its kernel ie. 32 bit or 64 bit.

The uname command gives you the solution. Execute the following command in terminal:


$ uname -a


If the result contains x86_64, its 64 bit kernel.

If the result contains i386 or i486 or i586 or i686, its 32 bit kernel.
