Verifying RHEL/CentOS is 32 Bit or 64 Bit System

We use “uname -a” command to verify a system, whether it is 32 bit or 64 bit.

The 32 bit system will show i686 i686 i386 GNU/Linux and 64 bit server shows x86_64 x86_64 x86_64 GNU/Linux.

So, it’s very easy to verify whether a system is 32 or 64 bit using “uname -a” command from the command line shell.
