How to determine whether a given Linux is 32 bit or 64 bit?

1. Using uname – prints information system

# uname -m
x86_64     ==> 64-bit kernel
i686       ==> 32-bit kernel

2. Using lscpu – displays information about the CPU information

# lscpu
Architecture:          x86_64
CPU op-mode(s):        32-bit, 64-bit
