Bash Scripting Tutorial – Real World Challenges

Welcome back! In this second video of my Bash scripting series, I’ll walk you through real-world Bash scripting examples — the kind of scripts that actually help automate tasks on a Linux system.

We’ll go beyond the basics and explore how to use:

Command-line arguments

User input

Arrays

Conditional logic

Loops

Functions

And even a bonus To-Do Tracker script using file handling!
