SYNOPSIS
       lshw [ -version ]

       lshw [ -help ]

       lshw [ -X ]

       lshw [  [ -html ]  [ -short ]  [ -xml ]	[ -json ]  [ -businfo ]	 ]  [ -dump filename ]	[ -class class... ]  [ -dis‐
       able test... ]  [ -enable test... ]  [ -sanitize ]  [ -numeric ]	 [ -quiet ]  [ -notime ]

DESCRIPTION
       lshw  is a small tool to extract detailed information on the hardware configuration of the machine. It can report ex‐
       act 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.

       -version
	      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 Notation).

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

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

       -dump filename
	      Display output and 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 detection), cpuid (for CPU detection), pci (for PCI/AGP access), isapnp (for ISA  PnP	 ex‐
	      tensions),  pcmcia  (for PCMCIA/PCCARD), ide (for IDE/ATAPI), usb (for USB devices),scsi (for SCSI) or network
	      (for network interfaces detection).

       -quiet Don't display status.

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

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

       -notime
	      Exclude volatile attributes (timestamps) from output.

BUGS
       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.

NOTES
       lshw must be run as super user or it will only report partial information.

FILES
       /usr/local/share/pci.ids

       /usr/share/pci.ids

       /etc/pci.ids

       /usr/share/hwdata/pci.ids
	      A list of all known PCI ID's (vendors, devices, classes and subclasses).	If compiled with zlib support,	lshw
	      will look for pci.ids.gz first, then for pci.ids.

       /proc/bus/pci/*
	      Used to access the configuration of installed PCI buses and devices.

       /proc/ide/*
	      Used to access the configuration of installed IDE buses and devices.

       /proc/scsi/*, /dev/sg*
	      Used to access the configuration of installed SCSI devices.

       /dev/cpu/*/cpuid
	      Used on x86 platforms to access CPU-specific configuration.

       /proc/device-tree/*
	      Used on PowerPC platforms to access OpenFirmware configuration.

       /proc/bus/usb/*
	      Used to access the configuration of installed USB buses and devices.

       /sys/* Used on 2.6 kernels to access hardware/driver configuration information.

EXAMPLES
       lshw -short
	      Lists hardware in a compact format.

       lshw -class disk -class storage
	      Lists all disks and storage controllers in the system.

       lshw -html -class network
	      Lists all network interfaces in HTML.

       lshw -disable dmi
	      Don't use DMI to detect hardware.
