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.
