Most users do not know how to collect information about the running OS version on their system. Even do not know how to find the installed version. In this tutorial, we will explore different commands through which you can check which Debian version is running on your Linux system.

Method 01: Check the Debian version using the Command line
Below, we have mentioned various commands through which you can check your Debian version on your Linux system.
Display Debian version using lsb_release
The lsb_release is a command-line utility that displays the LSB (Linux Standard Base) information about the running Linux operating system. It is recommended to use this method to check the Debian version.
The lsb_release command displays the LSB information about running Linux OS on your system. This command displays the information about any Debian version without considering which desktop environment you are using. Use the ‘lsb_release’ command in the following way to check debian version:
$ lsb_release –a
You can check the installed debian version in the description line. If you want to display the Debian version instead of displaying more information then, try the following command:
$ lsb_release -d
This command only displays the description of the installed Debian version.
Display debian version using the /etc/issue file
Using the /etc/issue file information, you can also check the currently running Debian version on your system. Using the cat command can display the content of the /etc/issue file on the terminal. Type the below-mentioned command to display the Debian version using the ‘/etc/issue’ file:
