Linux lspci command
The Linux lspci command is a handy utility used to display detailed information about all PCI buses and devices in the system. It helps users identify devices connected to the PCI bus such as graphics cards, network adapters, and storage controllers. By running lspci, you can quickly gather information about the hardware on your system, including the vendor, device ID, driver in use, and more. This command is often used for troubleshooting hardware-related issues or to gather information about the system configuration. Explore the different options available with lspci to customize the output according to your needs.
