Is my SUSE Linux 32 vs 64 Bit?

We can query Linux system configuration variables using the getconf command. Run the following command:
getconf LONG_BIT
Sample outputs:

64

For more info see my previous FAQ: “How do I know if my Linux is 32 bit or 64 bit?“. Finding a version helps us to install correct software and other utilities. In some cases, sysadmin and developers can patch their machine against known vulnerabilities. The goal is to keep your server safe and secure against bad guys. Hence, finding the OpenSUSE/SUSE version is an essential task for the OPs team.
