To find out the CPU architecture information on a Linux system, you can use the lscpu command. This command displays detailed information about the CPU architecture, including the CPU model, number of CPUs, CPU threads, and more.
For example, to display the CPU architecture information, you can use the following command:
lscpu
This command will display the CPU architecture information in a table format, with each row representing a different attribute of the CPU.
Here is an example of the output of the lscpu command:
Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian CPU(s): 8 On-line CPU(s) list: 0-7 Thread(s) per core: 2 Core(s) per socket: 4 Socket(s): 1 NUMA node(s): 1 Vendor ID: GenuineIntel CPU family: 6 Model: 63 Model name: Intel(R) Xeon(R) CPU E5-2650 v3 @ 2.30GHz Stepping: 2 CPU MHz: 2300.000 CPU max MHz: 2300.0000 CPU min MHz: 1200.0000 BogoMIPS: 4600.00 Virtualization: VT-x L1d cache: 32K L1i cache: 32K L2 cache: 256K L3 cache: 20480K NUMA node0 CPU(s): 0-7
You can use the -p option to display the information in a more parseable format, with each attribute separated by a colon:
lscpu -p
You can also use other options to display specific attributes of the CPU architecture, such as the CPU model or the number of CPUs. For more information about the lscpu command and its options, you can consult the man page or use the --help option.
