?? Day 8 of #90DaysOfDevOps Challenge: Bash Scripting Basics ???

Today, I explored the essentials of bash scripting, covering key concepts step by step. Here's how I tackled each task, along with command-line examples:

?? Task 1: Comments

• What I Learned: Comments in bash scripts start with # and are used to explain what different parts of the script do.
• Example:

?? Task 2: Echo

• What I Learned: The echo command displays messages in the terminal. It’s a simple way to print text or variable values.
• Example:

?? Task 3: Variables

• What I Learned: Variables in bash can store data that can be referenced by their name.
• Example:

? Task 4: Using Variables

• What I Learned: Variables can be used to perform operations like arithmetic.
• ?Example:

?? Task 5: Built-in Variables

• What I Learned: Bash has built-in variables that hold useful information, such as the script name ($0), the number of arguments ($#), and more.
• Example:

?

? Task 6: Wildcards

• What I Learned: Wildcards (*, ?, [ ]) are used to perform pattern matching for file operations.
• Example:

# List all files with a .txt extension in the current directory

# List all files starting with 'file' and ending in '.sh'

?? Submission Instructions

• Steps Taken: Combined all the tasks above into a single bash script. Added comments to explain each part of the script. Uploaded the script to a GitHub repository for review.

Day 8 was an exciting introduction to bash scripting, building a solid foundation for more complex tasks ahead. Can’t wait to dive into advanced concepts in the coming days! ??
