       lshw  [   [ ‐html ]  [ ‐short ]  [ ‐xml ]  [ ‐json ]  [ ‐businfo ]  ]  [

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.

       ‐json  Outputs the device tree as a JSON object (JavaScript Object Nota‐
              tion).

       ‐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  ex‐
              tensions),  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 in‐
              terfaces detection).

       ‐quiet Don’t display status.

       ‐sanitize
              Remove  potentially  sensitive  information  from  output (IP ad‐
              dresses, 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 re‐
       ported 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 sub‐
              classes).  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 de‐
              vices.

       /proc/ide/*
              Used to access the configuration of installed IDE buses  and  de‐
              vices.

       /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 de‐
              vices.

       /sys/* Used on 2.6 kernels to access hardware/driver  configuration  in‐
              formation.

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.
