lshw Command in Linux: Get Hardware Details
The lshw command lists the hardware details of your Linux system. You can categorize it to get details on different kinds of hardware.
While running any operating system, a user will find himself in a situation where he wants to know all the hardware details.
And when you're running Linux, there's nothing better than using the lshw (list hardware) command for that purpose.
So in this tutorial, I'm going to share multiple examples of how you can use the lshw command to get hardware info.
How to use the lshw command
To use the lshw command, you'd have to follow the simple command syntax:
lshw [-format] [options]
[-format]: is where you specify the output format between HTML, XML, JSON, sort (shows the hardware paths), and bus info (shows bus information).
[options]: Used to tweak the default behavior of the lshw command.
In case you're curious about the effects when executed without any additional flags or formatting options, here you have it:
It will give you every hardware detail possible with the lshw command and that's not the best way to use the lshw.
So let's look at how you can use the lshw command to derive specific information only.
1. Show network information
To display the network information, you'd have to use the
-C to specify the class and the
network as shown:
sudo lshw -C network
As you can see, I have two hardware devices for networking purposes: wifi and ethernet including its logical name and vendor.
2. Get the memory details
Using this method, you will get details of individual RAM slots and the cache, including information like RAM size, clock speed, etc.
And to do so, you'll be using the same
-C flag but with the
sudo lshw -C memory
What the above image suggests is I have 4 RAM slots, each equipped with 8GB of RAM and clocked at 2667MHz.
3. Get the storage information
By far this is the most useful way you can use the lshw command in my opinion as it lists all the connected storage devices with all the necessary information.
And to do so, you can use the lshw command in the following manner:
sudo lshw -class storage
4. Get the system information
The system information includes details like system architecture, motherboard name and manufacturer, and number of plug-and-play ports.
To get the system information, you use the
system flag as shown:
sudo lshw -C system
As you can see, I have a Gigabyte motherboard with 7 plug-and-play slots!
5. Get the sound card info
There are times when one wants to verify the manufacturer of the sound card and in that case, you can use the following command:
sudo lshw -C multimedia
6. Get the display controller information
If you want to know which GPU is being used to get the display output, then, you can use the lshw command with the
sudo lshw -C display
As I'm using the integrated graphics, it is showing the Intel product.
7. Display the PCIE bridge information
If you're looking for a way to get the PCIe bridge information, then, you'd have to use the
bridge flag as shown:
sudo lshw -C bridge
8. Display bus information
If you don't know, buses in computers are nothing but a communication system that is used to transfer data inside the system itself.
And if you want to list down the buses in your system, then, you can use the
bus flag with the lshw command as shown:
sudo lshw -C bus
As you can see, it listed all the buses including the USB.
9. Display CPU information
To get the details on the processor of your system, you can use the lshw command in this manner:
sudo lshw -C CPU
This will give you details on CPU type, manufacturer, clock speed, number of cores, threads and many more related things.
This is what you've learned so far
Here's the summary of the lshw command with the options used in this tutorial:
|Gets the details of the network hardware devices.
|Displays the details of RAM in your system.
|Prints details of the storage drives.
|Gets the details of the motherboard and plug-and-play slots.
|Details of the sound card of your system.
|Know more about what is powering the display output.
|Displays info about the PCIe bridges.
|It will list down buses and their details.
|List the processor details
