Simple Menu for User InputThis script will create an input screen in BASH that allows the user to enter information just as they would in a window. This is to show the use of simple functions as well as the tput command. "tput cup" allows the developer to place the cursor anywhere on the screen. There are many more commands that tput recognizes, see the man page for more information.#!/bin/bash
## Clears the screen and builds the user input screen
function screen() {
clear
