Chapter 2 - Writing a Rust Echo Clone –Part 1: Command-Line Arguments Explained

In this video, we dive into Chapter 2 Part 1 of the Command-Line Rust series and begin building a clone of the classic echo command. 🦀🔧 We'll explore how command-line arguments work in Linux and Rust, including flags, positional arguments, named parameters, and subcommands. You’ll learn how to start parsing input using Rust's powerful CLI tools and set the foundation for a robust command-line app.
By the end of this session, you'll understand:
✅ How CLI parameters are structured
✅ What makes an argument positional or optional
✅ How to begin implementing them in Rust
Perfect for Rust learners who want to write real tools from the ground up.
