Bash Shell Scripting - Creating User Menus - "select" Statement

The video tutorial introduces the select statement, which is useful for creating user menus in scripts. It demonstrates how to use the select statement to present options to users and handle their selections. The tutorial also covers using if statements to act on user choices and suggests replacing them with case statements for better script structure. By combining select and case, the tutorial shows how to create efficient and user-friendly scripts that maintain menu availability after actions are performed.

What is a key advantage of combining select and case statements in a script?
