NAME

lshw - list hardware SYNOPSIS

lshw [ -version ]

lshw [ -help ]

lshw [ -X ]

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

-dump filename ] [ -class class... ] [ -disable test... ] [ -enable

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 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.

-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 detec‐ tion), 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 net‐ work (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). 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 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). /proc/bus/pci/* Used to access the configuration of installed PCI busses and devices. /proc/ide/* Used to access the configuration of installed IDE busses 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 busses 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. SEE ALSO /proc/*, linuxinfo(1), lspci(8), lsusb(8) COPYING lshw is distributed under the GNU GENERAL PUBLIC LICENSE (GPL) version 2. AUTHOR lshw is maintained by Lyonel Vincent . OTHER INFO The webpage for lshw is at
