It will show all hw detailed information
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 -classclass. -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 sensible information from output (IP addresses, serial numbers, etc.). -numeric Also display numeric IDs (for PCI and USB devices).
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.
