SYNOPSIS
       lshw [ -version ]

       lshw [ -help ]

       lshw [ -X ]

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

       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.

       -json  Outputs  the device tree as a JSON object (JavaScript Object No-
              tation).

       -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 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/AT-
              API), usb (for USB devices),scsi (for SCSI) or network (for net-
              work interfaces 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).

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 busses and de-
              vices.

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