Hardware information
Like for every thing, there are plenty of commands to check information about the hardware of your linux system. Some commands report only specific hardware components like cpu or memory while the rest cover multiple hardware units.
This post takes a quick look at some of the most commonly used commands to check information and configuration details about various hardware peripherals and devices. The list includes lscpu, hwinfo, lshw, dmidecode, lspci etc.
1. lscpu
The lscpu command reports information about the cpu and processing units. It does not have any further options or functionality.

Summary
Each of the command has a slightly different method of extracting information, and you may need to try more than one of them, while looking for specific hardware details. However they are available across most linux distros, and can be easily installed from the default repositories.
On the desktop there are gui tools, for those who do not want to memorise and type commands. Hardinfo, I-nex are some of the popular ones that provide detailed information about multiple different hardware components.
Get hardware information on Linux with lshw command
Lshw – List hardware
Lshw is a nifty small command line utility that generates detailed reports about various hardware components on the system. It does so by reading different files in the /proc directory.
Lshw is capable of reporting memory configuration, firmware version, mainboard configuration, CPU version and speed, cache configuration, bus speed etc.
Install lshw
Ubuntu, Debian and Fedora users can get it from default repositories. On CentOS lshw can be installed from Epel repo.
# ubuntu, debian
$ sudo apt-get install lshw
# fedora, centos (epel)
$ sudo yum install lshw
Using lshw
The lshw command needs to run with super privileges to be able to detect and report the maximum amount of information. So run as root, or use sudo.
Lshw assorts hardware components into groups called “class”. Processor, memory, display, network, storage are all different classes.
1. Display full information
Running lshw without any options would generate full information report about all detected hardware. It would generate a big output with quite a lot of technical details
$ sudo lshw

2. Display information in short
With the “-short” the lshw command would generate a brief information report about the hardware devices that would quickly give an idea about the hardware profile of the system.
$ sudo lshw -short

The above output is easy to interpret. The system has an intel processor, 4 RAM slots, 1 500gb hard drive with 6 partitions, 1 dvd writer, 1 network adapter, couple of usb ports etc.
The 3rd column is the class name. Lshw can display information only about a particular class if requested with the “-class” options.
3. Display only memory information
To display information about the memory, specify the memory class
$ sudo lshw -short -class memory
H/W path Device Class Description
===================================================
/0/0/1 memory 2MiB L2 cache
/0/0/3 memory 32KiB L1 cache
/0/2 memory 32KiB L1 cache
/0/4 memory 64KiB BIOS

/0/14/0 memory 2GiB DIMM DDR2 Synchronous 667 MHz (1.5 ns)
/0/14/1 memory 2GiB DIMM DDR2 Synchronous 667 MHz (1.5 ns)
/0/14/2 memory 2GiB DIMM DDR2 Synchronous 667 MHz (1.5 ns)
/0/14/3 memory 2GiB DIMM DDR2 Synchronous 667 MHz (1.5 ns)
4. Display processor information
With class processor, lshw would display information about the cpu. It is better to not use the short option and get full details about the processor.
$ sudo lshw -class processor
*-cpu
description: CPU
product: Intel(R) Core(TM)2 Quad CPU Q8400 @ 2.66GHz
vendor: Intel Corp.
physical id: 0
bus info: cpu@0

It should be noted that lshw does not accurately tell about the number of cores or processing units available. The above system for example is a quadcore processor with 4 processing units. Another command called lscpu gives more accurate information about the cpu.
5. Disk drives
Display the disk drives with the disk class.
$ sudo lshw -short -class disk
[sudo] password for enlightened:
H/W path Device Class Description
===================================================
/0/1/0.0.0 /dev/sda disk 500GB ST3500418AS
/0/3/0.0.0 /dev/cdrom disk DVD RW DRU-190A
To display information about the partitions and controllers also, specify the storage and volume class along with the disk class. Then it would give a more clear picture about the storage on the system.
$ sudo lshw -short -class disk -class storage -class volume
H/W path Device Class Description
===================================================
/0/100/1c.2/0 storage JMB368 IDE controller

/0/1/0.0.0/2/5 /dev/sda5 volume 97GiB HPFS/NTFS partition
/0/1/0.0.0/2/6 /dev/sda6 volume 97GiB Linux filesystem partition
/0/1/0.0.0/2/7 /dev/sda7 volume 1952MiB Linux swap / Solaris partition
/0/1/0.0.0/2/8 /dev/sda8 volume 198GiB Linux filesystem partition
/0/3 scsi4 storage
/0/3/0.0.0 /dev/cdrom disk DVD RW DRU-190A
6. Network adapter information
Use the network class to display information about the network adapter/interface. Omitting the short option is a good idea to get detailed information about it.
$ sudo lshw -class network
*-network
description: Ethernet interface
product: 82566DC Gigabit Network Connection
vendor: Intel Corporation

resources: irq:43 memory:e0300000-e031ffff memory:e0324000-e0324fff ioport:20c0(size=32)
The value of the “serial” field is same as the MAC address. The configuration field indicates that autonegotiation is turned on and the current operating speed is 100Mbit/s. These configurations can be modified with the ethtool command.
7. Display address details with businfo
With the businfo option lshw would output the address details of pci, usb, scsi and ide devices
$ sudo lshw -businfo

The output is similar to “short” option, with the first column replaced with Bus Info.
8. Generate report in html/xml format
Lshw is capable of producing reports in html, xml and json formats.
$ sudo lshw -html > hardware.html
For xml format
$ sudo lshw -xml > hardware.xml
Summary
The above examples covered nearly most of what lshw can do. Check out the man page for full documentation.
Lshw also comes with a gui frontend called lshw-gtk that reports the same information in a minimal graphical user interface. Here is a screenshot.
There are many other gui tools for checking hardware information, like hardinfo that generate report in a more well organised manner and visually rich format.
Inxi is an amazing tool to check hardware information on Linux
Inxi
A very common thing linux users struggle with is to find what hardware has the OS detected and how well. Because unless the OS is aware of the hardware, it might not be using it at all. And there an entire ocean of commands to check hardware information.
There are quite a few gui tools like hardinfo, sysinfo etc on the desktop, but having a generic command line tool is far more useful and this is where Inxi works well. Inxi is a set of scripts that will detect a whole lot of information about the hardware, including vendor details, device driver configuration etc. And most importantly, it will print everything in a easy to read format.
Install inxi
Inxi is there in the default repos of most distros so just get it quick
# Ubuntu/Debian users
$ sudo apt-get install inxi
# CentOS/Fedora users
$ sudo yum install inxi
If inxi is not present on your distro, then install it by following the instructions here
https://code.google.com/p/inxi/wiki/Installation
Using inxi
Inxi comes with a huge list of options that will display more and more information about different hardware parts as much possible. So in this post we shall cover just some basics to get started and the rest you can explore.
1. Run Inxi
To get a one line snapshot of your hardware just run inxi like this.
$ inxi -c 5
CPU~Quad core Intel Core2 Quad CPU Q8400 (-MCP-) clocked at 1998.000 Mhz Kernel~3.11.0-12-generic x86_64 Up~1:43 Mem~4774.1/7975.7MB HDD~500.1GB(38.8% used) Procs~301 Client~Shell inxi~1.9.12
Color schemes - Inxi output is colored and if you need to change the color for better visibility just use the c option followed by a random number between 0-32.
2. Getting basic information
The b flag will present a good amount of basic information about the system.
$ inxi -c 5 -b
System: Host: enlightened Kernel: 3.11.0-12-generic x86_64 (64 bit) Desktop: KDE 4.11.2 Distro: Ubuntu 13.10
Machine: Mobo: Intel model: DG35EC version: AAE29266-210
Bios: Intel version: ECG3510M.86A.0112.2009.0203.1136 date: 02/03/2009
CPU: Quad core Intel Core2 Quad CPU Q8400 (-MCP-) clocked at 1998.00 MHz
Graphics: Card: Intel 82G35 Express Integrated Graphics Controller
X.Org: 1.14.3 drivers: intel (unloaded: fbdev,vesa) Resolution: 1360x768@60.0hz
GLX Renderer: Mesa DRI Intel 965G GLX Version: 2.1 Mesa 9.2.1
Network: Card: Intel 82566DC Gigabit Network Connection driver: e1000e

Info: Processes: 304 Uptime: 1:50 Memory: 4983.3/7975.7MB Client: Shell (bash) inxi: 1.9.12
The about output contains plenty of information, about the CPU, Graphics card, drives, and the OS installation. Very useful when installing drivers or diagnosing.
3. Print Hard drive partitions
Lets now print out the information about hard drive partitions. It will print out all the mounted partitions along with their mount points, and space usage.
$ inxi -p
Partition: ID: / size: 97G used: 22G (24%) fs: ext4 ID: /media/13f35f59-f023-4d98-b06f-9dfaebefd6c1 size: 196G used: 132G (71%) fs: ext4
ID: /media/4668484A68483B47 size: 98G used: 28G (29%) fs: fuseblk ID: swap-1 size: 2.05GB used: 0.00GB (0%) fs: swap
To print out the unmounted partitions along with the mounted ones, use the o option with p
$ inxi -p
Partition: ID: / size: 97G used: 22G (24%) fs: ext4 ID: /media/13f35f59-f023-4d98-b06f-9dfaebefd6c1 size: 196G used: 132G (71%) fs: ext4

enlightened@enlightened:~$ inxi -po
Partition: ID: / size: 97G used: 22G (24%) fs: ext4 ID: /media/13f35f59-f023-4d98-b06f-9dfaebefd6c1 size: 196G used: 132G (71%) fs: ext4
ID: /media/4668484A68483B47 size: 98G used: 28G (29%) fs: fuseblk ID: swap-1 size: 2.05GB used: 0.00GB (0%) fs: swap
Unmounted: ID: /dev/sda1 size: 75.16G label: N/A uuid: 5E38BE8B38BE6227
Print the hard drive details like make, model and size with D option
$ inxi -D
Drives: HDD Total Size: 500.1GB (38.8% used) 1: id: /dev/sda model: ST3500418AS size: 500.1GB
4. Optical drive details
Print out full list of drives, including all storage and optical drives along with their specifications.
$ inxi -d
Drives: HDD Total Size: 500.1GB (38.8% used) 1: id: /dev/sda model: ST3500418AS size: 500.1GB
Optical: /dev/sr0 model: N/A dev-links: cdrom
Features: speed: 12x multisession: yes audio: yes dvd: yes rw: cd-r,cd-rw,dvd-r,dvd-ram
That was quick.
5. Network interfaces and configurations
The n option simply prints out the details about the network interface along with the configuration details
$ inxi -n
Network: Card: Intel 82566DC Gigabit Network Connection driver: e1000e
IF: eth0 state: up speed: 100 Mbps duplex: full mac: 00:1c:c0:f8:79:ee
Use the i optio along with n to get ip address details (both wan and lan)
$ inxi -ni
Network: Card: Intel 82566DC Gigabit Network Connection driver: e1000e
IF: eth0 state: up speed: 100 Mbps duplex: full mac: 00:1c:c0:f8:79:ee
WAN IP: 122.163.33.2 IF: eth0 ip: 192.168.1.2
6. Show Audio/sound card and graphics card information
The A option is for audio information and G is for graphics card information
$ inxi -AG
Graphics: Card: Intel 82G35 Express Integrated Graphics Controller
X.Org: 1.14.3 drivers: intel (unloaded: fbdev,vesa) Resolution: 1360x768@60.0hz
GLX Renderer: Mesa DRI Intel 965G GLX Version: 2.1 Mesa 9.2.1
Audio: Card: Intel 82801H (ICH8 Family) HD Audio Controller driver: snd_hda_intel Sound: ALSA ver: k3.11.0-12-generic
The graphics card details are already included with the b option.
7. Show distro specific repository data
$ inxi -r

8. Print full information
The F option give a more detailed overview of the system compared to the b (basic) option. But it does not include everything that inxi is capable of reporting.
# inxi -F

Use the i option to print the ip address information
$ inxi -Fi
9. Print eXtra data
The x option can be used with individual options to print extended or extra information about that particular hardware or profile
To print addtional information about audio system
$ inxi -A -x
Audio: Card: Intel 82801H (ICH8 Family) HD Audio Controller driver: snd_hda_intel bus-ID: 00:1b.0
Sound: Advanced Linux Sound Architecture ver: k3.11.0-12-generic
To get extra information about any subset of hardware profile use the x option like above.
To get more extra information use -xx. To get even more extra information use -xxx. Inxi can’t give you anything more beyond that.
Summary
Each option prints out information about a specific hardware part. Select the ones needed or print all of it, either way its very simple and quick.

Check hardware information on Linux with hwinfo command
Hwinfo
The hwinfo command is a very handy command line tool that can be used to probe for details about hardware components. It reports information about most hardware units like cpu, hdd controllers, usb controllers, network card, graphics cards, multimedia, printers etc.
Hwinfo depends on the libhd library to gather hardware information which depends on libhal.
Hwinfo is available in the repositories of Ubuntu and Debian.
# ubuntu, debian
$ sudo apt-get install hwinfo
Using hwinfo
The help information explains how to use it
$ hwinfo --help
Usage: hwinfo [options]
Probe for hardware.
--short just a short listing
--log logfile write info to logfile
--debug level set debuglevel
--version show libhd version
--dump-db n dump hardware data base, 0: external, 1: internal
--hw_item probe for hw_item
hw_item is one of:
all, 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,
scanner, scsi, smp, sound, storage-ctrl, sys, tape, tv, usb, usb-ctrl,
vbe, wlan, zip
Note: 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.)
The options are few, just mention the hardware item for which you would like to see the information and it would display that only.
1. Display all information
Running hwinfo without any options would display detailed information about all hardware units
$ hwinfo
2. Display brief information
The “–short” option will display brief information about the hardware and not the details
$ hwinfo --short

3. View CPU details
With the “–cpu” option, hwinfo would display only cpu information.
$ hwinfo --short --cpu
cpu:
Intel(R) Core(TM)2 Quad CPU Q8400 @ 2.66GHz, 2000 MHz
Intel(R) Core(TM)2 Quad CPU Q8400 @ 2.66GHz, 2000 MHz
Intel(R) Core(TM)2 Quad CPU Q8400 @ 2.66GHz, 2666 MHz
Intel(R) Core(TM)2 Quad CPU Q8400 @ 2.66GHz, 2000 MHz
Remove the short option to display detailed information, about the cpu.

9. Log information to a file
The hwinfo has an option to log all data to a file. The following command will log detailed information about all hardware units to a text file.
$ hwinfo --all --log hardware_info.txt
To log short information in addition to the detailed information, add the “short” option too. Not sure if it is supposed to work like that.
$ hwinfo --all --short --log hardware_info.txt
