hwinfo(8)



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,  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

          Note that if this option is missing, no hardware probing will be
          done!

   --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.

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.
