🐧 Linux/Unix Learning

This repository contains my journey through learning Linux/Unix concepts, shell scripting, and system administration. It serves as both documentation of my progress and a reference for others interested in Linux/Unix systems.

📚 Course Structure

The repository is organized into three main parts, following the course curriculum:

Part 1: UNIX/LINUX Concepts & Commands ⌨️

  • Linux operating system overview
  • Linux file system structure
  • Basic and advanced file operations
  • Directory management
  • Command manipulation (piping, redirection)
  • Regular expressions and wildcards
  • File permissions and security
  • Text processing utilities (grep, cut, paste, tr)
  • File compression and archiving

Part 2: Shell Scripting / Shell Programming 📜

  • Script fundamentals and syntax
  • Variables and data manipulation
  • Control structures (if, case, loops)
  • Command line arguments
  • Function implementation
  • Arrays and complex data structures
  • Practical projects:
    • Secret Agent Application
