Introduction to Linux

What is Linux

Linux is an operating system just like Windows and MacOS. Unlike other operating systems, Linux is open-source which means anyone can look at its code, change it and share it freely.

Why Linux? Key Advantages

  • Free- It does not need any cost to download or copy.
  • Customizable-You can change the system to fit your needs
  • Secure- Linux is secure and has strong permissions and fewer malware threats.
  • Community driven- Millions of users and developers contribute worldwide.

How to start with Linux?

Choose a beginner-friendly distro:

  • Ubuntu (best for newcomers)
  • Linux Mint (simple and stable)
  • Kali Linux (for cybersecurity, but not ideal for beginners)

Install safely

Use VirtualBox (to run Linux inside Windows/macOS without risk).
Try Live USB (test Linux without installing).

Learn Basic Commands

  • ls # List files
  • cd # Change directory
  • pwd # Show current folder
  • mkdir # Create a directory
