NAME
       lshw - list hardware

SYNOPSIS
       lshw [ -version ]

       lshw [ -help ]

       lshw [ -X ]

       lshw  [ -html | -short | -xml | -businfo ] [ -class class ... ] [ -dis‐
       able test ... ] [ -enable test ... ] [  -sanitize  ]  [	-numeric  ]  [
       -quiet ]

DESCRIPTION
       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.

       -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.

       -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.

       -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.

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

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

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  informa‐
       tion.

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).

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

       /proc/ide/*
	      Used  to	access	the  configuration of installed IDE busses 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  busses  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.
