       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.

       -json  Outputs  the  device  tree  as  a JSON object (JavaScript Object

       -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.

       -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), 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  sensitive  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
