Today you will learn about a command which will help you to get information related to hardware and operating system.

In Linux, there are many commands, with the help of which we can extract information about hardware and software.

Here I have listed some of them:

• uname
• lshw
• lscpu
• lsblk
• lsusb
• dmidecode etc..

In this guide, I will explain to you about uname command.

Let’s get started.

uname is a very basic but useful command that helps you get some key information’s like:

• Operating System Name
• Kernel Name and Version
• Kernel Release Information
• Network node Hostname/System Hostname
• System Hardware Name
• Processor Information
• Hardware Platform/Architecture details

You must follow the syntax given below to use the uname command.

uname [OPTION]...

1. Print all Information

You can use -a option to print all the information’s that the uname command can provide.

In fact, you don’t need to remember any of uname command’s other options. Only this option will provide you all the information.

As you can see, uname has provided us with a lot of information related to hardware and software.

2. Display the Hostname Name

To display the Hostname of your system pass the -n option to uname.
