[CentOS] Commands to Check Version and 32bit/64bit Architecture

I’ll introduce commands to check CentOS version and whether it’s 32bit or 64bit.

Command to check CentOS version

cat /etc/redhat-release
CentOS release 6.4 (Final)

Command to check architecture (32bit, 64bit)

arch
# For 64bit
X86_64

# For 32bit
i686

That’s all from the Gemba.
