lshw is maintained by Lyonel Vincent <lyonel@ezix.org>.

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.

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 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 addresses.

       -dumpfilename
              Display output and dump collected information into a file (SQLite database).

       -classclass
              Only show the given class of hardware. class can be found using lshw-short or lshw-businfo.

       -Cclass
              Alias for -classclass.

       -enabletest-disabletest
              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.

Examples

lshw-short
              Lists hardware in a compact format.

       lshw-classdisk-classstorage
              Lists all disks and storage controllers in the system.

       lshw-html-classnetwork
              Lists all network interfaces in HTML.

       lshw-disabledmi
              Don't use DMI to detect hardware.

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.

Name

       lshw - list hardware

Notes

lshw must be run as super user or it will only report partial information.
