Looks like you need Expect. It's commonly used to respond to interactive prompts in shell programs based on file input.

Simply use that file as input:

program < file

For example, I want to select my timezone using the tzselect tool. For my timezone, I need to enter

Saving this contents into input.txt, I can run tzselect with

tzselect < input.txt

This gives the same output as if the values have been typed in manually.
