Definitive Guide to Checking Linux Version: Essential Tips for Linux Users

Checking the version of your Linux distribution is a common task that can be useful for various reasons. For example, you may need to check the version to ensure that you have the latest security updates installed or to troubleshoot a problem.

There are several ways to check the version of your Linux distribution. One common method is to use the `lsb_release` command. This command will print information about your Linux distribution, including the version number.

For example, to check the version of Ubuntu, you would run the following command:

lsb_release -a

This command would print output similar to the following:

No LSB modules are available.Distributor ID:UbuntuDescription:Ubuntu 22.04.1 LTSRelease:22.04Codename:jammy

Another common method for checking the version of your Linux distribution is to use the `/etc/os-release` file. This file contains information about your Linux distribution, including the version number.

To view the contents of the `/etc/os-release` file, you can use the following command:

cat /etc/os-release

This command would print output similar to the following:

NAME="Ubuntu"VERSION="22.04.1 LTS (Jammy Jellyfish)"ID=ubuntuID_LIKE=debianPRETTY_NAME="Ubuntu 22.04.1 LTS"VERSION_ID="22.04"HOME_URL="https://www.ubuntu.com/"SUPPORT_URL="https://help.ubuntu.com/"BUG_REPORT_URL="https://bugs.launchpad.net/ubuntu/"PRIVACY_POLICY_URL="https://www.ubuntu.com/legal/terms-and-conditions"VERSION_CODENAME=jammyUBUNTU_CODENAME=jammy

The version number of your Linux distribution is typically listed in the `VERSION` or `VERSION_ID` field.

1. Command line

In the context of checking the version of a Linux distribution, the command line plays a crucial role. Commands like `lsb_release -a` and `cat /etc/os-release` are essential tools for retrieving detailed information about the system’s version.

`lsb_release -a` is particularly useful as it provides comprehensive information about the Linux Standard Base (LSB) release, including the distributor ID, description, release number, and codename. This information is vital for identifying the specific Linux distribution and its version.
