Summary
Unlike most functions in this book, those presented in this chapter have little application at the command line; they are designed almost exclusively for use in other scripts. They are useful in interactive scripts such as games or data entry forms. They can be used for presentations (put a series of “slides” in a bash array, and move through them, forward or backward, with a keypress) or menus. They are not as fancy as GUI applications, but can be used to create impressive displays in very little time.
