lspci

lspci is a command on Unix-like operating systems that prints ("lists") detailed information about all PCI buses and devices in the system.[1] It is based on a common portable library libpci which offers access to the PCI configuration space on a variety of operating systems.

If many devices are shown as unknown (e.g. "Unknown device 2830 (rev 02)"), issuing the command update-pciids will usually correct this.

lsusb

lsusb[2] is a similar command for USB buses and devices. To make use of all the features of this program, you need to have a Linux kernel which supports the /proc/bus/usb interface (e.g., Linux kernel 2.3.15 or newer).

hwinfo

hwinfo[3] is for all the hardware.[4] Hwinfo output reports for various computer models are collected in a public GitHub repository.[5]

lshw

lshw is a subset of what hwinfo presents.[6][7]

Other platforms

The equivalent command for FreeBSD is pciconf -l. pciconf can also perform other functions such as reading and writing PCI registers. For more information, see the man page.

The HWiNFO tool, which is not related to the hwinfo tool mentioned above, can be downloaded in binary form at no cost. It is claimed to be a "system information and diagnostics comprehensive hardware analysis, monitoring and reporting for Windows and DOS".

Similar commands
  • dmesg — prints the message buffer of the kernel.
  • uname — prints the name, version and other details about the current machine and the operating system.
  • dmidecode — prints information from DMI interface from BIOS.
  • lscpu — prints information about CPU(s).
  • lsscsi — prints information about SCSI devices.
