There are many utilities available to check Linux system hardware information. Some commands report altogether like CPU, Processor, memory, storage, disk, etc,. and the rest will cover only specific hardware components like CPU or processor or memory, etc,.
In this tutorial we are going to cover about Linux System Devices Information utilities such as lspci, lsscsi, lsusb, and lsblk.
'lspci for Windows' - familiar lspci-like tool from Linux in both GUI and CLI form on Windows helps you find drivers for your unknown PCI devices on Windows reports devices with drivers issues. The lspci command, which can be found in the pciutils package, is a great tool for finding information on the devices in your PC. The lspci command will allow you to get the model number/chip details for devices such as network interface cards, sound cards, raid cards, etc. Lspci is a command that lists PCI devices and buses. It is helpful for determining what devices are connected and supported; the output of lspci is often requested for troubleshooting purposes.
This tutorial takes a quick look at some of the most commonly used commands to check information and configuration details about various hardware devices.
1) What’s lspci – List PCI Bus Devices
lspci stands for list PCI devices. lspci command is used to display information about PCI buses in the system and hardware devices that are connected to PCI and PCI bus.
It will display information about model number/chip details for devices like PCI bridge, VGA controller, Ethernet controller, USB controller, Audio device, IDE interface, etc,.,
lspci doesn’t come stand alone utility and its part of the pciutils package.
By default, it shows a brief list of devices which are attached in the system, so filter out specific device information with grep for better view.
