7 commands to check and collect Linux hardware information

On Linux systems, there are a number of commands that can be used to query the hardware information of the host. Some commands are only for specific hardware components, such as CPU, memory, and some commands can query multiple hardware information.

This article is simply to let everyone understand the basic command to use to query hardware information, including lscpu, hwinfo, lshw, lspci, lsblk, lsusb and so on.

1. lscpu is used to query CPU information

 
 [root@devops ~]# lscpu 
 
 Architecture: x86_64 
 
 CPU Op-mode(s): 32-bit, 64-bit 
 
 Byte Order: Little Endian 
 
 CPU(s): 1 
 
 On-line CPU(s) List: 0 
 
 Thread(s) per core: 1 
 
 Core(s) per socket: 1 
 
 CPU socket(s): 1 
 
 NUMA node(s): 1 
 
 Vendor ID: GenuineIntel 
 
 CPU family: 6 
 
 Model: 45 
 
 Stepping: 7 
 
 CPU MHz: 2194.842 
 
 BogoMIPS: 4389.68 
 
 Hypervisor vendor: Xen 
 
 Virtualization type: full 
 
 L1d cache: 32K 
 
 L1i cache: 32K 
 
 L2 cache: 256K 
 
 L3 cache: 15360K 
 
 NUMA node0 CPU(s): 0 

 2. lshw Display hardware information table
 this Make the application universal, it can list a variety of different hardware parameters through personal needs: CPU, memory, hard disk, USB controller, lshw card, etc., essentially extract the corresponding hardware information from different files in the /proc directory. . 
 Follow the steps below to install the lshw tool, and then you can use it. 
 
 wget http://ezix.org/software/files/lshw-B.02.14.tar.gz 
 
 tar -zxvf lshw-B.02.14.tar .gz 
 
 cd lshw-B.02.14 
 
 make && make install 
 
 Example: 
 
 [root@devops lshw-B.02.14 ]# lshw -short
