DESCRIPTION

20       lshw  is  a  small tool to extract detailed information on the hardware
21       configuration of the machine. It can report exact memory configuration,
22       firmware version, mainboard configuration, CPU version and speed, cache
23       configuration, bus speed, etc. on DMI-capable x86 or IA-64 systems  and
24       on some PowerPC machines (PowerMac G4 is known to work).
25
26       It  currently  supports  DMI  (x86 and IA-64 only), OpenFirmware device
27       tree (PowerPC only), PCI/AGP, CPUID (x86), IDE/ATA/ATAPI, PCMCIA  (only
28       tested on x86), SCSI and USB.
29
30       -version
31              Displays the version of lshw and exits.
32
33       -help  Displays the available command line options and quits.
34
35       -X     Launch the X11 GUI (if available).
36
37       -html  Outputs the device tree as an HTML page.
38
39       -xml   Outputs the device tree as an XML tree.
40
41       -json  Outputs  the  device  tree  as  a JSON object (JavaScript Object
42              Notation).
43
44       -short Outputs the device tree showing hardware paths, very  much  like
45              the output of HP-UX's ioscan.
46
47       -businfo
48              Outputs the device list showing bus information, detailing SCSI,
49              USB, IDE and PCI addresses.
50
51       -dump filename
52              Display output  and  dump  collected  information  into  a  file
53              (SQLite database).
54
55       -class class
56              Only  show the given class of hardware. class can be found using
57              lshw -short or lshw -businfo.
58
59       -C class
60              Alias for -class class.
61
62       -enable test
63
64       -disable test
65              Enables or disables a test. test  can  be  dmi  (for  DMI/SMBIOS
66              extensions),  device-tree  (for  OpenFirmware  device tree), spd
67              (for memory Serial Presence  Detect),  memory  (for  memory-size
68              guessing  heuristics),  cpuinfo  (for kernel-reported CPU detec‐
69              tion), cpuid (for CPU  detection),  pci  (for  PCI/AGP  access),
70              isapnp (for ISA PnP extensions), pcmcia (for PCMCIA/PCCARD), ide
71              (for IDE/ATAPI), usb (for USB devices),scsi (for SCSI)  or  net‐
72              work (for network interfaces detection).
73
74       -quiet Don't display status.
75
76       -sanitize
77              Remove   potentially   sensitive  information  from  output  (IP
78              addresses, serial numbers, etc.).
79
80       -numeric
81              Also display numeric IDs (for PCI and USB devices).
82

BUGS

84       lshw currently does not detect Firewire(IEEE1394) devices.
85
86       Not all architectures supported by GNU/Linux are fully supported  (e.g.
87       CPU detection).
88
89       "Virtual"  SCSI  interfaces  used  for  SCSI emulation over IDE are not
90       reported correctly yet.
91

NOTES

93       lshw must be run as super user or it will only report partial  informa‐
94       tion.

FILES

97       /usr/local/share/pci.ids
98
99       /usr/share/pci.ids
100
101       /etc/pci.ids
102
103       /usr/share/hwdata/pci.ids
104              A list of all known PCI ID's (vendors, devices, classes and sub‐
105              classes).  If compiled with zlib support,  lshw  will  look  for
106              pci.ids.gz first, then for pci.ids.
107
108       /proc/bus/pci/*
109              Used  to  access  the  configuration  of installed PCI buses and
110              devices.
111
112       /proc/ide/*
113              Used to access the configuration  of  installed  IDE  buses  and
114              devices.
115
116       /proc/scsi/*, /dev/sg*
117              Used to access the configuration of installed SCSI devices.
118
119       /dev/cpu/*/cpuid
120              Used on x86 platforms to access CPU-specific configuration.
121
122       /proc/device-tree/*
123              Used on PowerPC platforms to access OpenFirmware configuration.
124
125       /proc/bus/usb/*
126              Used  to  access  the  configuration  of installed USB buses and
127              devices.
128
129       /sys/* Used on 2.6  kernels  to  access  hardware/driver  configuration
130              information.
