       lshw - list hardware


       lshw [ -version ]

       lshw [ -help ]

       lshw [ -X ]

       lshw  [  -html  |  -short  |  -xml  | -businfo ] [ -class class ... ] [

       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.

       -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.

       -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 detection).

       -quiet Don’t display status.

              Remove   potentially   sensible   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

       lshw -short
              Lists hardware in a compact format.

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

              Lists all network interfaces in HTML.

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