Linux Hardware Information: Modern Commands

Older Linux systems sometimes used utilities such as lsdev to summarise installed hardware. On modern distributions, a small set of more focused commands usually gives better information.

Useful hardware commands

• lspci — PCI devices such as network, storage and graphics controllers.
• lsusb — USB devices.
• lsblk — block devices and storage layout.
• lscpu — CPU architecture and topology.
• dmidecode — firmware-reported system information where supported.

lspci
lsusb
lsblk
lscpu

For driver and kernel details, combine these with lspci -k, journalctl -k, or dmesg as appropriate.

This page replaces the old lsdev-specific note with a more useful modern hardware-discovery reference.
