lshw -short
Lists hardware in a compact format.
lshw -class disk -class storage
Lists all disks and storage controllers in the system.

Lists all network interfaces in HTML.
lshw -disable dmi
Don’t use DMI to detect hardware.
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 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).

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

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.
