Expect is a powerful scripting language that interacts with any programs which require user interaction. For example, if you want to automatically run a program which expects the end user to type a password and provide some arguments, Expect can automate it for you. The way it works is that it expects input and provides a response without you having to type anything. You can integrate it with your shell scripts to achieve more efficient results.
