Get hardware information on Linux with lshw command
Linux By Silver Moon On Apr 7, 2014 0 Comments
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

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.

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

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. Check out
the following post
8 commands to check cpu information on Linux
5. Disk drives
Display the disk drives with the disk class.
$ sudo lshw -short -class disk

===================================================
/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

/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

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.

the following post
8 commands to check cpu information on Linux
5. Disk drives
Display the disk drives with the disk class.
$ sudo lshw -short -class disk
[sudo] password for enlightened:

===================================================
/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

/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

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.

Get hardware information on Linux with lshw command
Linux By Silver Moon On Apr 7, 2014 0 Comments
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

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

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. Check out
the following post

Linux By Silver Moon On Apr 7, 2014 0 Comments
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

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

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

vendor: Intel Corp.
physical id: 0

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. Check out
the following post
8 commands to check cpu information on Linux
5. Disk drives
Display the disk drives with the disk class.
$ sudo lshw -short -class disk

===================================================
/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

/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

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.

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

/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

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.

Get hardware information on Linux with lshw command
Linux By Silver Moon On Apr 7, 2014 0 Comments
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

/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

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. Check out
the following post
8 commands to check cpu information on Linux
5. Disk drives
Display the disk drives with the disk class.
$ sudo lshw -short -class disk
[sudo] password for enlightened:

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
