Final answer:
The question involves creating a bash script that displays a user menu, handles user input, and uses a while loop, typically taught at the college level in Computer Science or IT courses.
Step-by-step explanation:
The subject of this question is writing a bash script on a Linux machine, specifically for creating a user menu, capturing user input, and controlling the flow of the script with a while loop. This task is common in systems programming and scripting courses in a college-level Computer Science or Information Technology curriculum.
The script would typically start by presenting a menu to the user with various options. The user's input is then captured and depending on the input, different sections of the script are executed. A while loop ensures that the menu is re-displayed to the user until a certain condition to exit is met, such as selecting an option like 'Quit'.
To create such a bash script, you may use the read command to get user input, a while loop to continue prompting the user until a certain condition is met, and case or if statements to handle the different menu options. The scripting is usually done in a plain text editor and run in a terminal on an Ubuntu Linux system.
