NAME

       hwinfo - probe for hardware

SYNOPSIS

       hwinfo [ OPTIONS ]

DESCRIPTION

       hwinfo  is used to probe for the hardware present in the system. It can
       be used to generate a system overview log which can be later  used  for
       support.

OPTIONS

       Note  that  running hwinfo without any options is roughly equivalent to
       'hwinfo --all --log=-'.

       --<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,  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 data about devices with DEVNAME will be shown.

       --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.

       --verbose
              Increase verbosity. Only together with --map.

       --log FILE
              Write log info to FILE.

       --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.

ENVIRONMENT

       hwprobe  can  hold  a comma-separated list of probing flags preceded by
       '+' or '-' to be turned on or off. To get a complete list of  supported
       flags, run 'hwinfo -all' (note: not '--all') and look at the top of the
       output.

       hwinfo also looks at /proc/cmdline for a hwprobe option.

EXAMPLES

       - show all disks
              hwinfo --disk

       - just an overview
              hwinfo --short --block

       - show a particular disk
              hwinfo --disk --only /dev/sdb

       - save disk config state
              hwinfo --disk --save-config=all

       - try 4 graphics card ports for monitor data (default: 3)
              hwprobe=bios.ddc.ports=4 hwinfo --monitor

       FILES

       /var/lib/hardware/hd.ids
              External hardware data base (in readable  text  form).  Try  the
              --dump-db option to see the format.

       /var/lib/hardware/udi
              Directory  where  persistent config data are stored (see --save-
              config option).

BUGS

       Not all hardware can be detected.
