Bash Scripting Module 3 – Functions, Arrays & I/O Redirection | EduTech

Welcome to Module 3 of our DevOps Bash Scripting series! In this video, we dive deep into three powerful concepts that take your scripting skills to the next level.

🔹 Functions in Bash – Learn how to write reusable code blocks, pass arguments, return values, and manage variable scope (local vs global).

🔹 Arrays in Bash – Master indexed arrays and associative arrays, plus how to add, remove, update, and loop through array elements.

We wrap up with a real-world case study: building a modular backup script using functions, arrays, and output logging.

📘 Perfect for beginners and intermediate learners in DevOps and Linux.
