Linux "lshw" Command Line Options and Examples
lshw is a small tool to extract detailed information on the hardware configuration of the machine. It can report exact memory config‐ uration, 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).
lshw [ -version ]
Command Line Options:
Displays the version of lshw and exits.
lshw -version ...
Displays the available command line options and quits.
lshw -help ...
Launch the X11 GUI (if available).
lshw -X ...
Outputs the device tree as an HTML page.
lshw -html ...
Outputs the device tree as an XML tree.
lshw -xml ...
lshw -json ...
Outputs the device tree showing hardware paths, very much like the output of HP-UX's ioscan.
lshw -short ...
Outputs the device list showing bus information, detailing SCSI, USB, IDE and PCI addresses.
lshw -businfo ...
Dump collected information into a file (SQLite database).
lshw -dump ...
Only show the given class of hardware. class can be found using lshw -short or lshw -businfo.
lshw -class ...
Alias for -class class.
lshw -C ...
Enables or disables a test. test can be dmi (for DMI/SMBIOS extensions), device-tree (for OpenFirmware device tree), spd (formemory 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 (forIDE/ATAPI), usb (for USB devices),scsi (for SCSI) or network (for network interfaces detection).
lshw -disable ...
Don't display status.
lshw -quiet ...
Remove potentially sensitive information from output (IP addresses, serial numbers, etc.).
lshw -sanitize ...
Also display numeric IDs (for PCI and USB devices).BUGSlshw 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.NOTESlshw 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.idsA 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/*/cpuidUsed 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.EXAMPLESlshw -shortLists hardware in a compact format.lshw -class disk -class storageLists all disks and storage controllers in the system.lshw -html -class networkLists all network interfaces in HTML.lshw -disable dmiDon't use DMI to detect hardware.
