How to find the linux processor / chip architecture

Question

What command should I use to find the processor / chip architecture on Linux?

linux-x86-32 linux-x86-64 linux-ppc-64 

Answer 1

To display kernel architecture: uname -a

To display cpu details: cat /proc/cpuinfo

Answer 2

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.
