lshw command in Linux with examples

Hi Friends! Today we learn lshw command in Linux with Examples.

lshw command is mainly used to check the list of hardware and Configuration in your server and PC.

But while using lshw command got the error like “lshw command not found“.

You can see in the screenshot that lshw command not found, So we have to install the lshw command in centos

#yum install lshw -y

Same we can install the lshw command in Ubuntu by using apt

#apt install lshw

So after installation, now we can use the lshw command in our Terminal.

# lshw

But the output is very huge, so we will use -short option with

-short to make the output short

# lshw -short

-class option to show only the specific class of Hardware.

# lshw -class CPU

Let’s use -short option with -class option and get the output for the processor, memory, a disk with volume, and a network.

# lshw -short -class cpu

# lshw -short -class memory

# lshw -short -class network

# lshw -short -class disk

# lshw -short -class volume

-html option is used to show the output in HTML format.

We get all the hardware lists in HTML format and we can save that into a file. By using the below command.

# lshw -html > hardware_list.html

-xml option is used to show the output in xml format.

We get all the hardware lists in XML format and we can save that into a file. By using the below command.

-json option is used to show the output in json format.

We get all the hardware lists in JSON format and we can save that into a file. By using the below command.

# lshw -json > hardware_list.json

-sanitize option is used to hide sensitive information from the output.

We can use this command to hide the information like serial Number.

# lshw -sanitize

The above output we have a yellow highlighted part and there is a parameter like “serial: [REMOVED]”

# lshw -class cpu -sanitize

# lshw -class disk -sanitize

To List all the HARDWARE in your current System

Example:
#lshw

To make the output short with lshw command 

Example:
#lshw -short 

To search by the TYPE of Hardware 

Example:
#lshw -class cpu          ** This is for CPU **
#lshw -class memory  ** This is for RAM **
#lshw -class disk          ** This is for DISK **
#lshw -class volume    ** This is for partition **
#lshw -class network  ** This is for Network **

To hide the sensitive Information like serail number. 

Example:
#lshw -sanitize
#lshw -class cpu -sanitize 
#lshw -class memory -sanitize 
#lshw -class disk  -sanitize
#lshw -class volume  -sanitize
#lshw -class network  -sanitize

To get the output in HTML Format 

Example:
#lshw -html

** To take a html format in one file **
#lshw -html > hardware_list.html 

To get the output in XML Format 

Example:
#lshw -xml

** To take a xml format in one file **
#lshw -xml > hardware_list.xml 

To get the output in JSON Format 

Example:
#lshw -json

** To take a json format in one file **
#lshw -json > hardware_list.json
