Usage: hwinfo [OPTIONS] Probe for hardware. Options: --<HARDWARE_ITEM> This option can be given more than once. Probe for a particular HARDWARE_ITEM. Available hardware items are: all, arch, bios, block, bluetooth, braille, bridge, camera, cdrom, chipcard, cpu, disk, dsl, dvb, fingerprint, floppy, framebuffer, gfxcard, hub, ide, isapnp, isdn, joystick, keyboard, memory, mmc-ctrl, modem, monitor, mouse, netcard, network, partition, pci, pcmcia, pcmcia-ctrl, pppoe, printer, redasd, reallyall, scanner, scsi, smp, sound, storage-ctrl, sys, tape, tv, uml, usb, usb-ctrl, vbe, wlan, xen, zip --short Show only a summary. Use this option in addition to a hardware probing option. --listmd Normally hwinfo does not report RAID devices. Add this option to see them. --only DEVNAME This option can be given more than once. If you add this option only entries in the device list matching DEVNAME will be shown. Note that you also have to specify --<HARDWARE_ITEM> to trigger any device probing. --save-config SPEC Store config for a particular device below /var/lib/hardware. SPEC can be a device name, an UDI, or 'all'. This option must be given in addition to a hardware probing option. --show-config UDI Show saved config data for a particular device. --map If disk names have changed (e.g. after a kernel update) this prints a list of disk name mappings. Note that you must have used --save-config at some point before for this can work. --debug N Set debug level to N. The debug info is shown only in the log file. If you specify a log file, the debug level is implicitly set to a reasonable value (N is a bitmask of individual flags). --verbose Increase verbosity. Only together with --map. --log FILE Write log info to FILE. Don't forget to also specify --<HARDWARE_ITEM> to trigger any device probing. --dump-db N Dump hardware data base. N is either 0 for the external data base in /var/lib/hardware, or 1 for the internal data base. --version Print libhd version. --help Print usage.
