HWINFO(8) System configuration 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
- 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.
