In this lesson, you will learn how to repeat commands using for and while loops.

A for loop is useful when working with a list of values, files, users, or numbers. A while loop continues running as long as a specified condition remains true.

You will also learn how to control loops with commands such as break and continue.

The lesson introduces functions as reusable groups of commands. Functions help organize scripts, reduce repeated code, and make scripts easier to understand and maintain.

By the end of this lesson, you should be able to automate repetitive tasks using loops and organize your scripts using functions.
