lshw is a small tool to extract detailed information on the hardware
configuration of the machine. It can report exact memory configuration,
firmware version, mainboard configuration, CPU version and speed, cache
configuration, bus speed, etc. on DMI-capable x86 or IA-64 systems and
on some PowerPC machines (PowerMac G4 is known to work).

It currently supports DMI (x86 and IA-64 only), OpenFirmware device
tree (PowerPC only), PCI/AGP, CPUID (x86), IDE/ATA/ATAPI, PCMCIA (only
tested on x86), SCSI and USB.

Displays the version of lshw and exits.

-help Displays the available command line options and quits.

-X Launch the X11 GUI (if available).

-html Outputs the device tree as an HTML page.

-xml Outputs the device tree as an XML tree.

-json Outputs the device tree as a JSON object (JavaScript Object

-short Outputs the device tree showing hardware paths, very much like
the output of HP-UX’s ioscan.

Outputs the device list showing bus information, detailing SCSI,
USB, IDE and PCI addresses.

-dump filename
Dump collected information into a file (SQLite database).

-class class
Only show the given class of hardware. class can be found using
lshw -short or lshw -businfo.

-C class
Alias for -class class.

-enable test

-disable test
Enables or disables a test. test can be dmi (for DMI/SMBIOS
extensions), device-tree (for OpenFirmware device tree), spd
(for memory Serial Presence Detect), memory (for memory-size
guessing heuristics), cpuinfo (for kernel-reported CPU detec‐
tion), cpuid (for CPU detection), pci (for PCI/AGP access),
isapnp (for ISA PnP extensions), pcmcia (for PCMCIA/PCCARD), ide
(for IDE/ATAPI), usb (for USB devices),scsi (for SCSI) or net‐
work (for network interfaces detection).

-quiet Don’t display status.

Remove potentially sensitive information from output (IP
addresses, serial numbers, etc.).

Also display numeric IDs (for PCI and USB devices).


lshw currently does not detect Firewire(IEEE1394) devices.

Not all architectures supported by GNU/Linux are fully supported (e.g.
CPU detection).

“Virtual” SCSI interfaces used for SCSI emulation over IDE are not
reported correctly yet.

lshw must be run as super user or it will only report partial informa‐
