       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 Notation).

       -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 information.





              A list of all known PCI ID's (vendors, devices, classes and subclasses).

              Used to access the configuration of installed PCI busses and devices.

              Used to access the configuration of installed IDE busses and devices.

       /proc/scsi/*, /dev/sg*
              Used to access the configuration of installed SCSI devices.

              Used on x86 platforms to access CPU-specific configuration.

              Used on PowerPC platforms to access OpenFirmware configuration.

              Used to access the configuration of installed USB busses and devices.

       /sys/* Used on 2.6 kernels to access hardware/driver configuration information.


       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.
