How to determine version of Linux?

Determining the Version of Linux

Determining the version of Linux can be a daunting task, especially for those who are new to the operating system. With numerous distributions available, it can be challenging to identify the exact version of Linux. However, in this article, we will guide you through the process of determining the version of Linux.

Step 1: Check the Package Manager

The first step in determining the version of Linux is to check the package manager. The package manager is responsible for managing the packages installed on your system. The most common package managers used in Linux are:

• APT (Advanced Package Tool): APT is the default package manager for Ubuntu and other Debian-based distributions.
• YUM (Yellowdog Updater, Modified): YUM is the default package manager for Red Hat and other Fedora-based distributions.
• zypper: ZYpper is the package manager for openSUSE.

To check the version of Linux using APT, YUM, or ZYpper, follow these steps:

• Open a terminal on your system.
• Type the following command to check the version of Linux:

  dpkg -l | grep linux

• This command will display a list of packages installed on your system, including the version of Linux.

Step 2: Check the Kernel Version

The kernel version is another important piece of information that can help you determine the version of Linux. The kernel is the core component of the operating system that manages hardware resources.

To check the kernel version, follow these steps:

• Open a terminal on your system.
• Type the following command to check the kernel version:

  uname -r

• This command will display the kernel version.

Step 3: Check the Package Version

The package version is another important piece of information that can help you determine the version of Linux. The package version is the version of the package that is installed on your system.

To check the package version, follow these steps:

• Open a terminal on your system.
• Type the following command to check the package version:

  dpkg -s <package_name>

• Replace <package_name> with the name of the package that you want to check.

Step 4: Check the System Information

The system information is another important piece of information that can help you determine the version of Linux. The system information includes information about the hardware, software, and configuration of your system.

To check the system information, follow these steps:

• Open a terminal on your system.
• Type the following command to check the system information:

  cat /etc/os-release

• This command will display a file that contains information about the operating system, including the version.

Significant Points to Keep in Mind

• Ubuntu and Debian-based distributions: Ubuntu and Debian-based distributions use the APT package manager, while other distributions use YUM or ZYpper.
• Red Hat and Fedora-based distributions: Red Hat and Fedora-based distributions use the YUM package manager.
• OpenSUSE: OpenSUSE uses the ZYpper package manager.
• Package version: The package version is the version of the package that is installed on your system.
• Kernel version: The kernel version is the version of the kernel that is installed on your system.

Conclusion

Determining the version of Linux can be a challenging task, but with the steps outlined in this article, you can easily identify the version of Linux on your system. By checking the package manager, kernel version, and system information, you can determine the exact version of Linux that is installed on your system. Remember to keep in mind the differences between APT, YUM, and ZYpper, as well as the differences between Ubuntu and Debian-based distributions, Red Hat and Fedora-based distributions, and OpenSUSE.

Additional Tips

• Use the dpkg -s command: The dpkg -s command is used to check the package version.
• Use the uname -r command: The uname -r command is used to check the kernel version.
• Use the cat /etc/os-release command: The cat /etc/os-release command is used to check the system information.
• Use the dpkg -l | grep linux command: The dpkg -l | grep linux command is used to check the package list and identify the version of Linux.
