       lshw [ -version ]

       lshw [ -help ]

       lshw [ -X ]

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

       -quiet ]  [ -notime ]

DESCRIPTION
       lshw is a small tool to extract detailed information on the hardware configuration of the ma‐
       chine. 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 sys‐
       tems 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  ad‐
              dresses.

       -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  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.

       -sanitize
              Remove  potentially  sensitive  information from output (IP addresses, 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 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).  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 devices.

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