How to check if the distribution is Debian-based in Linux

# Introduction

In this lab, you will learn how to determine if a Linux distribution is based on Debian. Understanding the underlying distribution is crucial for package management and system administration. You will use fundamental Linux commands to inspect system files and utilities that provide details about the operating system.

Specifically, you will use `cat /etc/os-release` to examine core OS information, `lsb_release -a` to verify distribution details, and `cat /etc/apt/sources.list` to inspect the package manager's configuration, all of which help identify Debian-based systems.
