In this guide, we will explore the step-by-step process of verifying the Ubuntu version using the command line, empowering users to stay informed and in control of their Ubuntu environment.
Checking Ubuntu Version
You can check your Ubuntu version using the command line.
To begin, open the terminal and enter the command ‘lsb_release -a.’ This will provide comprehensive version identification and release number detection. The ‘lsb_release’ command stands for Linux Standard Base and offers a convenient way to retrieve version information.
Additionally, you can use the ‘cat /etc/lsb-release’ command to achieve the same result. Both commands display essential details such as the distribution ID, description, release number, and codename of your Ubuntu installation.
This method is efficient and preferred by users who seek a quick and accurate way to ascertain their Ubuntu version without navigating through graphical user interfaces. Embracing these command-line tools promotes productivity and empowers users with a deeper understanding of their system’s specifications.
Using Lsb_Release Command
The identification of your Ubuntu version can be achieved using the ‘lsb_release’ command in the terminal. This command is a part of the LSB (Linux Standard Base) and provides certain information about the Linux distribution. When used with certain options, it can be used to retrieve system information in a script automation process. The ‘lsb_release’ command simplifies the retrieval of specific system information, making it a valuable tool for system administrators and developers. Below is a table highlighting some of the key options available with the ‘lsb_release’ command:
|Display all information
|Show the description of the distribution
|Display the codename of the distribution
|Show the ID of the distribution
Utilizing the ‘lsb_release’ command with these options can streamline system information retrieval and facilitate script automation.
Checking Release Name

Finding Release Codename
To find the release codename of your Ubuntu version, you can use the command line. The release codename is essential for understanding version naming conventions and finding release end of life dates.
Here’s how to find the release codename using the command line:
- Open the terminal on your Ubuntu system.
- Type the command lsb_release -a and press Enter.
- Look for the ‘Codename’ field in the output.
- The codename corresponds to a specific Ubuntu release, providing insight into its development cycle and support duration.
Understanding the release codename is crucial for staying informed about end of life dates and planning for system upgrades or migrations.
This approach empowers users to stay current and make informed decisions based on the release codename.
Understanding Version Codenames
The process of understanding version codenames involves verifying the release codename of your Ubuntu version using the command line. Understanding version history and exploring version differences can provide valuable insights into the evolution and improvements of Ubuntu releases. The table below showcases some of the notable Ubuntu version codenames and their corresponding release numbers.
Identifying Release Number
The identification of the release number is essential for verifying your Ubuntu version using the command line. To determine the release number, follow these steps:
- Use the lsb_release command with the -r option to display the release number.
- Check the /etc/lsb-release file using the cat command to find the release number.
- Utilize the hostnamectl command with the status option to show the operating system release.
- Access the /etc/os-release file using the cat command to retrieve the release number.
- Use the command lsb_release -a to display detailed information including the release number.
Displaying Ubuntu Kernel Version
You can further understand the details of your Ubuntu version by displaying the kernel version using the command line. The kernel serves as the core component of the operating system, managing system resources and enabling interaction between hardware and software.
To display the Ubuntu kernel version, enter ‘uname -r’ in the command line interface.
Staying updated with kernel updates is crucial for enhancing system stability and security. Kernel updates often include bug fixes, performance improvements, and security patches, contributing to a smoother and more secure computing experience.
Checking Ubuntu Architecture
Verifying Ubuntu architecture through the command line provides essential insights into the system’s underlying hardware configuration. It allows users to identify the system platform and check the system architecture, which is crucial for installing software and drivers tailored to the specific hardware setup.
Here are some commands to check Ubuntu architecture:
uname -m: This command displays the machine hardware name.
dpkg --print-architecture: It shows the architecture of the system as recognized by the package manager.
lscpu: This command provides comprehensive information about the CPU architecture.
file /bin/bash: It reveals the architecture of the operating system’s default shell.
arch: This command displays the architecture of the current system.
Verifying Ubuntu Desktop Environment
Verifying the Ubuntu desktop environment is essential for understanding the graphical user interface and system functionality.
Using command line tools, users can easily check the desktop environment and confirm the Ubuntu version they are running.
Verifying the desktop environment ensures that users have the correct information about their system, allowing them to troubleshoot issues effectively.
Checking Desktop Environment
To determine the desktop environment on your Ubuntu system, use the command line to display the current session’s environment. You can utilize the following commands to gain insights into the desktop environment:
echo $XDG_CURRENT_DESKTOP: This command reveals the default environment set for the user.
cat /etc/X11/default-display-manager: It indicates the default display manager used by the system.
