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.
