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.
