SYNOPSIS
lshw [ -version ]

lshw [ -X ]
lshw [ -html | -short | -xml |
-businfo ] [ -class class ... ] [
-disable test ... ] [ -enable

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.
- -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.
- -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.
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).
- /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.
