Man Lshw  Command

This tutorial shows the man page for man lshw in linux.

Open terminal with 'su' access and type the command as shown below:
man lshw

Result of the Command Execution shown below:

LSHW(1)                                                                                                                                                      LSHW(1)

lshw is a small tool to extract detailed information on the hardware configuration of the machine. It can report exact memory configuration, firmware ver Äê
sion, 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),

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.

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 net Äê
work interfaces detection).

quiet Don't display status.

Remove potentially sensible information from output (IP addresses, serial numbers, etc.).

Also display numeric IDs (for PCI and USB devices).

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.

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




A list of all known PCI ID's (vendors, devices, classes and subclasses).

Used to access the configuration of installed PCI busses and devices.

Used to access the configuration of installed IDE busses and devices.

/proc/scsi/*, /dev/sg*
Used to access the configuration of installed SCSI devices.

Used on x86 platforms to access CPU specific configuration.

/proc/device tree/*
Used on PowerPC platforms to access OpenFirmware configuration.

Used to access the configuration of installed USB busses and devices.

/sys/* Used on 2.6 kernels to access hardware/driver configuration information.

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.

/proc/*, linuxinfo(1), lspci(8), lsusb(8)
