Introduction to Linux

What is Linux?

Linux is an open-source operating system kernel that serves as the foundation for various Linux distributions (distros). It's free, highly customizable, and widely used in servers, desktops, and embedded systems.

Why Linux for Developers?

• Free and Open-Source: No licensing costs, and you can modify the source code.
• Command Line Proficiency: Essential for development tasks like version control, deployment, and automation.
• Stability and Security: Less prone to viruses compared to other OSes.
• Package Management: Easy installation of development tools.
• Community Support: Vast resources and forums for troubleshooting.

Linux Distributions

There are many Linux distributions. For beginners and developers, popular choices include:

• Ubuntu: User-friendly, based on Debian.
• Debian: Stable and reliable, great for servers.
• Fedora: Cutting-edge, backed by Red Hat.
• Arch Linux: Minimalist, for advanced users.

For this tutorial, we'll focus on Debian, as it's stable and commonly used in production environments.
