HWINFO(8) System configuration HWINFO(8)NAMEhwinfo - probe for hardware
SYNOPSIShwinfo [ OPTIONS ]
DESCRIPTIONhwinfo 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, key‐
board, memory, modem, monitor, mouse, netcard, network, parti‐
tion, 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
- 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.
