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 No-
tation).
-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
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 ex-
tensions), 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/AT-
API), usb (for USB devices),scsi (for SCSI) or network (for net-
work interfaces detection).
-quiet Don't display status.
-sanitize
Remove potentially sensitive information from output (IP ad-
dresses, 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 re-
ported 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). 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 de-
vices.
/proc/ide/*
Used to access the configuration of installed IDE buses and de-
vices.
/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 de-
vices.
/sys/* Used on 2.6 kernels to access hardware/driver configuration in-
formation.
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.
