16 commands to check hardware information on Linux

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.

Again, use grep to filter out only those file systems that you want to see

$ mount | column -t | grep ext

13. free – Check RAM

Check the amount of used, free and total amount of RAM on system with the free command.

$ free -m
             total       used       free     shared    buffers     cached
Mem:          7975       5865       2110          0         24        622
-/+ buffers/cache:       5218       2757
Swap:         1951        921       1030

14. dmidecode

The dmidecode command is different from all other commands. It extracts hardware information by reading data from the SMBOIS data structures (also called DMI tables).

# display information about the processor/cpu
$ sudo dmidecode -t processor

# memory/ram information
$ sudo dmidecode -t memory

# bios details
$ sudo dmidecode -t bios

Check out the man page for more details.

15. /proc files

Many of the virtual files in the /proc directory contain information about hardware and configurations. Here are some of them

CPU/Memory information

# cpu information
$ cat /proc/cpuinfo

# memory information
$ cat /proc/meminfo

Linux/kernel information

$ cat /proc/version
Linux version 3.11.0-12-generic (buildd@allspice) (gcc version 4.8.1 (Ubuntu/Linaro 4.8.1-10ubuntu7) ) #19-Ubuntu SMP Wed Oct 9 16:20:46 UTC 2013

16. hdparm

The hdparm command gets information about sata devices like hard disks.

$ sudo hdparm -i /dev/sda

/dev/sda:

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

/0/3/0.0.0      /dev/cdrom  disk        DVD RW DRU-190A

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                       memory      8GiB System Memory
/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
       version: Intel(R) Core(TM)2 Quad CPU    Q8400  @ 2.66GHz
       slot: LGA 775
       size: 2664MHz
       capacity: 4GHz
       width: 64 bits
       clock: 333MHz
       capabilities: fpu fpu_exception wp vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx x86-64 constant_tsc arch_perfmon pebs bts rep_good nopl aperfmperf pni dtes64 monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr pdcm sse4_1 xsave lahf_lm dtherm tpr_shadow vnmi flexpriority cpufreq

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
/0/100/1f.2                 storage     82801H (ICH8 Family) 4 port SATA Controller [IDE mode]
/0/100/1f.5                 storage     82801HR/HO/HH (ICH8R/DO/DH) 2 port SATA Controller [IDE m
/0/1            scsi3       storage     
/0/1/0.0.0      /dev/sda    disk        500GB ST3500418AS
/0/1/0.0.0/1    /dev/sda1   volume      70GiB Windows NTFS volume
/0/1/0.0.0/2    /dev/sda2   volume      395GiB Extended partition
/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
       physical id: 19
       bus info: pci@0000:00:19.0
       logical name: eth0
       version: 02
       serial: 00:1c:c0:f8:79:ee
       size: 100Mbit/s
       capacity: 1Gbit/s
       width: 32 bits
       clock: 33MHz
       capabilities: pm msi bus_master cap_list ethernet physical tp 10bt 10bt-fd 100bt 100bt-fd 1000bt-fd autonegotiation
       configuration: autonegotiation=on broadcast=yes driver=e1000e driverversion=2.3.2-k duplex=full firmware=1.1-0 ip=192.168.1.2 latency=0 link=yes multicast=yes port=twisted pair speed=100Mbit/s
       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
Bus info          Device      Class       Description
=====================================================
                              system      ()

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.

lshw gtk

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 
Drives:    HDD Total Size: 500.1GB (38.8% used)
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 
           ID: /media/4668484A68483B47 size: 98G used: 28G (29%) fs: fuseblk ID: swap-1 size: 2.05GB used: 0.00GB (0%) fs: swap 
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
Repos:     Active apt sources in file: /etc/apt/sources.list
           deb http://in.archive.ubuntu.com/ubuntu/ saucy main restricted
           deb-src http://in.archive.ubuntu.com/ubuntu/ saucy main restricted

           Active apt sources in file: /etc/apt/sources.list.d/google-chrome.list
           deb http://dl.google.com/linux/chrome/deb/ stable main

On CentOS you would get something like this

# inxi -r
Repos:     Active yum sources in file: /etc/yum.repos.d/CentOS-Base.repo
           base ~ http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os
           updates ~ http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates
           extras ~ http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=extras
           Active yum sources in file: /etc/yum.repos.d/epel.repo
           epel ~ https://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=$basearch
           Active yum sources in file: /etc/yum.repos.d/nginx.repo
           nginx ~ http://nginx.org/packages/centos/$releasever/$basearch/

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
System:    Host: dhcppc3 Kernel: 2.6.32-358.11.1.el6.x86_64 x86_64 (64 bit)

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.

linux hwinfo command

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

Save it to a file

$ hwinfo --short > hardware_brief.txt

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.

4. Display network card information

$ sudo hwinfo --short --netcard
network:                                                        
  eth0                 Intel 82566DC Gigabit Network Connection

<h4>5. Storage devices and partitions</h4>

[term]
$ sudo hwinfo --short --block

                       JMicron JMB368 IDE controller

7. USB devices and controllers

$ sudo hwinfo --short --usb
mouse:                                                          
  /dev/input/mice      Microsoft Basic Optical Mouse v2.0
hub:

                       Linux 3.11.0-12-generic ehci_hcd EHCI Host Controller

8. Display multiple devices together

To display multiple hardware units together, just add all the options

$ sudo hwinfo --short --usb --cpu --block
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

    Hello Web Admin, I noticed that your On-Page SEO is is missing a few factors, for one you do not use all three H tags in your post, also I notice that you are not using bold or italics properly in your SEO optimization. On-Page SEO means more now than ever since the new Google update: Panda. No longer are backlinks and simply pinging or sending out a RSS feed the key to getting Google PageRank or Alexa Rankings, You now NEED On-Page SEO. So what is good On-Page SEO?First your keyword must appear in the title.Then it must appear in the URL.You have to optimize your keyword and make sure that it has a nice keyword density of 3-5% in your article with relevant LSI (Latent Semantic Indexing). Then you should spread all H1,H2,H3 tags in your article.Your Keyword should appear in your first paragraph and in the last sentence of the page. You should have relevant usage of Bold and italics of your keyword.There should be one internal link to a page on your blog and you should have one image with an alt tag that has your keyword….wait there’s even more Now what if i told you there was a simple WordPress plugin that does all the On-Page SEO, and automatically for you? That’s right AUTOMATICALLY, just watch this 4minute video for more information at. Seo Plugin
