This article mainly introduces "how to view hardware information under Linux". In daily operation, I believe many people have doubts about how to view hardware information under Linux. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful for you to answer the doubts about "how to view hardware information under Linux". Next, please follow the editor to study!

Lshw

Lshw this command is a more general-purpose tool, it can list the local hardware information in detail. But this command is not available in all distributions, such as Fedora, which is not available by default and needs to be installed on its own.

Lshw can extract hardware information from various / proc files, such as CPU, memory, usb controller, hard disk, etc. If there is no option, the information listed will be very long, and when the-short option is added, only the summary information will be listed.

[alvin@VM_0_16_centos] $sudo lshw-short # length relationship The following results include deletion of Hash W path Device Class Description = = system Bochs / 0 bus Motherboard / 0Unip 0 memory 96KiB BIOS / 0ta 401 processor Intel ( R) Xeon (R) CPU E5-26xx v4 / 0 to 1000 memory 2GiB System Memory / 0 to 1000 memory 2GiB DIMM RAM / 0 to 100 bridge 440FX-82441FX PMC [Natoma] / 0 to 100 bridge 82371SB PIIX3 ISA [Natoma/] Triton II] / 0/100/1.1/0.1.0 / dev/cdrom disk QEMU DVD-ROM / 0/100/1.2/1 usb1 bus UHCI Host Controller / 0/100/1.3 bridge 82371AB/EB/MB PIIX4 ACPI / 0/100/4/0/1 / dev/vda1 volume 49GiB EXT3 volume / 0/100/5 generic Virtio memory balloon / 0/100/5/0 generic Virtual I/O device / 0/1 system PnP device PNP0b00 / 0/2 input PnP device PNP0303

Lscpu

Lscpu can list information about the native CPU, and this command has no options or parameters.

[alvin@VM_0_16_centos ~] $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 Socket (s): 1 NUMA node (s): 1 Vendor ID: GenuineIntel CPU family: 6 Model: 79 Model name: Intel (R) Xeon (R) CPU E5-26xx v4 Stepping: 1 CPU MHz: 2399.988 BogoMIPS: 4799.97 Hypervisor vendor: KVM Virtualization type: full L1d cache: 32K L1i cache: 32K L2 cache: 4096K NUMA node0 CPU (s): 0

Lsusb

Lsusb lists information about all USB devices connected to this computer. By default, only summary information is listed, and the details of each USB port can be listed using the-v option.

[alvin@VM_0_16_centos] $lsusb Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp. SMSC9512/9514 Fast Ethernet Adapter Bus 001 Device 002: ID 0424 ID 1d6b:0002 Linux Foundation 9514 Standard Microsystems Corp. SMC9514 Hub Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Lsscsi

Lsscsi can list SCSI/SATA device information such as hard disk / optical drive.

[alvin@VM_0_16_centos ~] $lsscsi [0VOV 01VOV 0] cd/dvd QEMU QEMU DVD-ROM 1.2. / dev/sr0

Lspci

Lspci lists all PCI buses, as well as details of all devices connected to the PCI bus, such as VGA adapters, video cards, network adapters, usb ports, SATA controllers, and so on.

[alvin@VM_0_16_centos ~] $lspci 00RV 00.0 Host bridge: Intel Corporation 440FX-82441FX PMC [Natoma] (rev 02) 00RU 01.0 ISA bridge: Intel Corporation 82371SB PIIX3 ISA [Natoma/Triton II] 00RH 01.1 IDE interface: Intel Corporation 82371SB PIIX3 IDE [Natoma/Triton II] 00RV 01.2 USB controller: Intel Corporation 82371SB PIIX3 USB [Natoma/Triton II] (rev 01) 01.3 Bridge: Intel Corporation 82371AB/EB/MB PIIX4 ACPI (rev) 03) 00Rose 02.0 VGA compatible controller: Cirrus Logic GD 5446 00Rd 03.0 Ethernet controller: Red Hat Inc Virtio network device 00:04.0 SCSI storage controller: Red Hat, Inc Virtio block device 00:05.0 Unclassified device [00ff]: Red Hat, Inc Virtio memory balloon

Df

The df command can list the size, usage, usage, mount point and other information of different partitions, plus the-h option can represent the size in k, M, G and other units, otherwise the default is bytes, which is not easy to read.

[alvin@VM_0_16_centos ~] $df-h Filesystem Size Used Avail Use% Mounted on / dev/vda1 50G 7.5G 40G 16% / devtmpfs 911M 0911M 0% / devtmpfs 920M 68K 920m 1% / dev/shm tmpfs 920M 364K 920m 1% / run tmpfs 920M 0920M 0% / sys/fs/cgroup tmpfs 184m 0 184m 0% / run/user/0 tmpfs 184M 0 184m 0% / run/user/1001 tmpfs 184M 0 184m 0% / run/user/1000

Free

The free command looks at the total number of idle, and RAM used on the system, typically with the-m parameter.

[alvin@VM_0_16_centos] $free-m total used free shared buff/cache available Mem: 1839 221 156 0 1461 1400 Swap: 00 this is the end of the study on "how to view hardware information under Linux".
