lspci is a command on Unix-like operating systems that prints ("lists") detailed information about all PCI buses and devices in the system. It is based on a common portable library libpci which offers access to the PCI configuration space on a variety of operating systems.
Example output on a Linux system:
# lspci 00:00.0 Host bridge: Intel Corporation 82815 815 Chipset Host Bridge and Memory Controller Hub (rev 11) 00:02.0 VGA compatible controller: Intel Corporation 82815 Chipset Graphics Controller (CGC) (rev 11) 00:1e.0 PCI bridge: Intel Corporation 82801 Mobile PCI Bridge (rev 03) 00:1f.0 ISA bridge: Intel Corporation 82801BAM ISA Bridge (LPC) (rev 03) 00:1f.1 IDE interface: Intel Corporation 82801BAM IDE U100 Controller (rev 03) 00:1f.2 USB Controller: Intel Corporation 82801BA/BAM USB Controller #1 (rev 03) 00:1f.3 SMBus: Intel Corporation 82801BA/BAM SMBus Controller (rev 03) 00:1f.4 USB Controller: Intel Corporation 82801BA/BAM USB Controller #2 (rev 03) 00:1f.5 Multimedia audio controller: Intel Corporation 82801BA/BAM AC'97 Audio Controller (rev 03) 01:03.0 CardBus bridge: O2 Micro, Inc.

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

lsusb 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).
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 `System Information and Diagnostics Comprehensive Hardware Analysis, Monitoring and Reporting for Windows and DOS'.
- 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 your CPU(s).
