Lspci displays hardware device information through the system bus

Lspci-list all PCI devices

Popularization of pci:

PCI (Peripheral Component Interconnect) is a bus standard that connects the motherboard of an electronic computer and external devices.

Common PCI cards include NICs, sound cards, modem, TV cards, and disk controllers, as well as USB and serial ports. The original video card is usually a PCI device, but soon its bandwidth is insufficient to support the performance of the video card. PCI graphics cards are currently only used when an additional external display or motherboard is not equipped with an AGP or PCI Express slot.

Let's take a look at the effect of lspci execution. We can view the hardware information:

Lspci-v | grep 8192 view detailed information (if there are too many information, use grep to filter it out ):

$ lspci -v | grep 819204:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8192EE PCIe Wireless Network Adapter    Kernel driver in use: r8192ee

Lspci-VV | grep 8192 For more details (distinct, there are no differences between the two ):

$ lspci -vv | grep 819204:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8192EE PCIe Wireless Network Adapter    Kernel driver in use: r8192ee

Lpci-K

$ lspci -k | grep 819204:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8192EE PCIe Wireless Network Adapter    Kernel driver in use: r8192ee

The others are more profound and I will not read them for the time being. Today there are still many commands that need to be popularized.
