Find out if your Linux installation is 32 bit or 64 bitUname -i gives you the hardware-platform. If you are possibly getting unknown, you can use uname -a to get all the information to find if it is 32-Bit or 64-Bit. Anything that is x86_64 is 64 bit and anything that i386, i686 or similar is 32 bit.
Get CPU Info in Linux The simplest way to determine what type of CPU you have is by displaying the contents of the /proc/cpuinfo virtual file. Identifying the type of processor using the proc/cpuinfo file does not require installing any additional programs. It will work no matter what Linux distribution you are using.
To display kernel architecture: uname -a
To display cpu details: cat /proc/cpuinfo

In the terminal, type
lscpu which returns output like this:
Architecture: i686 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian CPU(s): 2 On-line CPU(s) list: 0,1 Thread(s) per core: 1 Core(s) per socket: 2 Socket(s): 1 Vendor ID: GenuineIntel CPU family: 6 Model: 23 Stepping: 6 CPU MHz: 2670.000 BogoMIPS: 5320.13 L1d cache: 32K L1i cache: 32K L2 cache: 3072K To only get the architecture:
lscpu | grep Architecture Which in this case is
Architecture: i686 See man lscpu for more.
