Shell scripting in Bash is an essential skill for any development environment. It allows for automating tasks, managing systems efficiently, and performing repetitive tasks with ease. In this guide, we will walk through some fundamental concepts of shell scripting with practical tasks to solidify your understanding.

Task 1: Comments

In bash scripts, comments are used to add explanatory notes or disable certain lines of code.

Task 2: Echo

The echo command is used to display messages on the terminal. It's a basic but powerful way to interact with the user and display information.

Task 3: Variables

Variables in bash are used to store data and can be referenced by their name. They help in making scripts dynamic and reusable.

Task 4: Using Variables

Now that you have declared variables, let's use them to perform a simple task. This script takes two variables (numbers) as input and prints their sum using those variables.

Task 5: Using Built-in Variables

Bash provides several built-in variables that hold useful information. Your task is to create a bash script that utilizes at least three different built-in variables to display relevant information.

Task 6: Wildcards

Wildcards are special characters used to perform pattern matching when working with files. Your task is to create a bash script that utilizes wildcards to list all the files with a specific extension in a directory.

Create a single bash script that completes all the tasks mentioned above.
