The Importance of Checking Linux Version
If you are a Linux user, it is important to know the version of the operating system you are using. This knowledge is crucial for troubleshooting issues, installing software, and ensuring compatibility with hardware devices. In this article, we will discuss how to check the Linux version using four different methods. But before we dive into that, let’s first have a basic understanding of Linux and its components.
The Basics of Linux
Linux is an open-source operating system that was first introduced in 1991 by Linus Torvalds. It is based on the Unix operating system, which was developed in the 1970s. Unlike proprietary operating systems like Windows and macOS, Linux can be modified and distributed by anyone. This has led to the development of many different Linux distributions, each with its own set of features and characteristics.
Linux Components
Linux consists of several components, including:
- Kernel: the core of the operating system that interacts with hardware devices and manages system resources
- Shell: a command-line interface that enables users to interact with the operating system
- Filesystem: a hierarchical structure that organizes files and directories on the system
- Applications: software programs that run on the operating system
Linux Distributions
While Linux is the core operating system, each distribution is a complete package that includes the Linux kernel, system utilities, libraries, and applications. According to IONOS, there are many free, open-source Linux distributions built from the Linux kernel. Some of the most popular Linux distributions include:
- Ubuntu: a user-friendly distribution that is ideal for beginners
- Debian: a stable and reliable distribution that is popular for servers
- Fedora: a bleeding-edge distribution that is ideal for developers
- Arch Linux: a minimalist distribution that is highly customizable
Each distribution has its own unique features and characteristics, making it important to understand which one you are using.
The Difference between Kernel and Linux-based Operating Systems
In the previous section, we discussed the components of Linux and the different distributions available. In this section, we will discuss the difference between the kernel and Linux-based operating systems.
The Kernel
According to Tecmint, the kernel is the core of the operating system that interacts directly with the computer’s hardware. It manages system resources, such as memory and CPU time, and provides an interface for software to interact with the hardware. The kernel is responsible for managing processes, handling input/output operations, and controlling hardware devices.
Linux-based Operating Systems
A Linux-based operating system, also known as a distribution, is a complete package that includes the Linux kernel, system utilities, libraries, and applications. According to Linuxize, there are many different Linux distributions available, each with its own set of features and characteristics. Some of the most popular distributions include Ubuntu, Debian, Fedora, and Arch Linux.
The Difference
While the kernel is the core of the operating system, the Linux distribution provides a complete package that includes the kernel, system utilities, libraries, and applications. According to GeeksforGeeks, understanding the difference between the kernel and Linux-based operating systems is important for troubleshooting and understanding how the operating system works.
How to Check Linux Version
Knowing the version of the Linux operating system you are using is important for troubleshooting issues, installing software, and ensuring compatibility with hardware devices. In this section, we will discuss four different methods for checking the Linux version.
Method 1: Using the os-release File
According to GeeksforGeeks, the os-release file is a standard file that contains information about the Linux distribution version, name, and ID. To check the Linux version using the os-release file, follow these steps:
- Open the terminal
- Run the following command:
cat /etc/os-release
- The information about the distribution will be displayed on the screen, including the version number, name, and ID.
Method 2: Using the lsb_release Command
The lsb_release
command is used to display Linux Standard Base (LSB) information about the distribution. According to Tecmint, this command is available on most Linux distributions. To check the Linux version using the lsb_release
command, follow these steps:
- Open the terminal
- Run the following command:
lsb_release -a
- The information about the distribution will be displayed on the screen, including the version number, name, and ID.
Method 3: Using the hostnamectl Command
According to Linuxize, the hostnamectl
command is used to display system information, including the Linux distribution version. To check the Linux version using the hostnamectl
command, follow these steps:
- Open the terminal
- Run the following command:
hostnamectl
- The information about the distribution will be displayed on the screen, including the version number.
Method 4: Using the GUI
If you prefer a graphical user interface (GUI), you can check the Linux version using the system settings. According to Linuxiac, the steps to check the Linux version using the GUI can vary depending on the distribution and desktop environment. However, in most cases, you can follow these steps:
- Open the system settings
- Look for the “About” or “Details” option
- The information about the distribution will be displayed, including the version number.
Now that you know how to check the Linux version using these four methods, you can easily troubleshoot issues, install software, and ensure compatibility with hardware devices.
Wrapping Up
In this article, we discussed the basics of Linux, including its components and distributions. We also discussed the difference between the kernel and Linux-based operating systems. Finally, we provided four different methods for checking the Linux version, including using the os-release file, lsb_release command, hostnamectl command, and GUI.
By knowing the version of the Linux operating system you are using, you can troubleshoot issues, install software, and ensure compatibility with hardware devices. We hope this article has been helpful in providing you with the knowledge you need to check your Linux version.
