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, pcm-
	      cia-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

       - monitor detection runs the Video BIOS to get the monitor data; dump a complete BIOS code execution trace to the log
	      hwprobe=bios.ddc.ports=1,x86emu=trace:dump:trace.only=0:dump.only=0 hwinfo --monitor --log=foo

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.
