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.
- Displays the available command line options and quits.
- Launch the X11 GUI (if available).
- Outputs the device tree as an HTML page.
- Outputs the device tree as an XML tree.
- 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
- -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
detection), 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 network (for network interfaces
- Don't display status.
- Remove potentially sensitive information from output (IP
addresses, serial numbers, etc.).
- Also display numeric IDs (for PCI and USB devices).

Not all architectures supported by GNU/Linux are fully supported (e.g. CPU
"Virtual" SCSI interfaces used for SCSI emulation over IDE are not
reported correctly yet.
