In the last chapter, you learned about using decision-making in scripts by working with test, if-else, and switch case. We also used select for loop with menu.
For repeated tasks, such as processing lists, you learned to use the for and while loops and the dowhile. You also learned about how to control loops using the break and continue statements.
