Linux 2.6 - man page for lshw (linux section 1)

LSHW(1) 										  LSHW(1)

NAME
       lshw - list hardware

SYNOPSIS
       lshw [ -version ]

       lshw [ -help ]

       lshw [ -X ]

       lshw [  [ -html ]  [ -short ]  [ -xml ]	[ -json ]  [ -businfo ]  ]  [ -dump filename ]	[
       -class class... ]  [ -disable 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  configura-
       tion,  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
	      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), mem-
	      ory (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 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).

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).

       /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.
