.SH NAME
hwinfo \- probe for hardware
.\"
.SH SYNOPSIS
.B hwinfo [
.I OPTIONS
.B ]
.\"
.SH DESCRIPTION
.B 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.
.\"
.SH OPTIONS
Note that running \fBhwinfo\fR without any options is roughly equivalent
to 'hwinfo \-\-all \-\-log=\-'.
.TP
\fB--<\f[BI]HARDWARE_ITEM\fB>\fR
This option can be given more than once.
Probe for a particular \fIHARDWARE_ITEM\fR. 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
.TP
\fB--short\fR
Show only a summary. Use this option in addition to a hardware probing
option.
.TP
\fB--listmd\fR
Normally hwinfo does not report RAID devices. Add this option to see them.
.TP
\fB--only \fIDEVNAME\fR
This option can be given more than once. If you add this option, only data
about devices with \fIDEVNAME\fR will be shown.
.TP
\fB--save-config \fISPEC\fR
Store config for a particular device below /var/lib/hardware. \fISPEC\fR
can be a device name, an UDI, or 'all'. This option must be given in addition to
a hardware probing option.
.TP
\fB--show-config \fIUDI\fR
Show saved config data for a particular device.
.TP
\fB--map\fR
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.
.TP
\fB--debug \fIN\fR
Set debug level to \fIN\fR. 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.
.TP
\fB--verbose\fR
Increase verbosity. Only together with \-\-map.
.TP
\fB--log \fIFILE\fR
Write log info to \fIFILE\fR.
.TP
\fB--dump-db \fIN\fR
Dump hardware data base. \fIN\fR is either 0 for the external data base in
/var/lib/hardware, or 1 for the internal data base.
.TP
\fB--version\fR
Print libhd version.
.TP
\fB--help\fR
Print usage.
.\"
.SH ENVIRONMENT
\fBhwprobe\fR 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 \fBhwprobe\fR option.

.SH EXAMPLES
.TP
- show all disks
hwinfo \-\-disk
.TP
- just an overview
hwinfo \-\-short \-\-block
.TP
- show a particular disk
hwinfo \-\-disk \-\-only /dev/sdb
.TP
- save disk config state
hwinfo \-\-disk \-\-save-config=all
.TP
- try 4 graphics card ports for monitor data (default: 3)
hwprobe=bios.ddc.ports=4 hwinfo \-\-monitor
.TP
.\"
.SH FILES
.TP
\fB/var/lib/hardware/hd.ids\fR
External hardware data base (in readable text form). Try the \-\-dump-db option to see the format.
.TP
\fB/var/lib/hardware/udi\fR
Directory where persistent config data are stored (see \-\-save-config option).
.\"
.SH BUGS
Not all hardware can be detected.
