Welcome to this in-depth UNIX tutorial! 🌐
In this session, we’ll cover some of the most powerful and frequently used concepts in UNIX shell scripting — including loops, arithmetic operations, and conditional statements.
Everything is explained step-by-step with syntax, examples, and live terminal execution for better understanding. 💻

🔹 What You’ll Learn in This Video

1️⃣ Arithmetic Operations in UNIX
➤ Learn how to perform addition, subtraction, multiplication, and division using expr, $(( )), and bc.
➤ Understand integer and floating-point calculations.

2️⃣ For Loops (5 Types Explained)
➤ Classic numeric for loop
➤ For loop using a list of values
➤ For loop with command substitution
➤ For loop with range and increment
➤ For loop reading from files or arguments
➤ Each type demonstrated with syntax + real example

3️⃣ While Loops (2 Types)
➤ Basic while loop (condition-based iteration)
➤ While loop for file processing
➤ Syntax and example demonstration

4️⃣ Until Loop
➤ Learn how until loops work opposite to while loops
➤ Syntax and example demonstration

5️⃣ If-Else Statements
➤ Understand how to make decisions using if-else conditions
➤ Real-world examples with arithmetic and string comparisons

6️⃣ If-Else Ladder
➤ Handle multiple conditions using nested if and elif statements

7️⃣ Case Statement
➤ Simplify complex conditional logic with case in shell scripting
➤ Used for menu-driven programs or multi-choice scripts

✨ Each topic is demonstrated practically with syntax, example, and output explanation — making it easy to follow even for beginners!
