How to add yes/no input in bash?

Question

bash

I started to learn bash and a couple of questions appeared in which Google did not help:

1. How to add a question-action to the script, so that if the answer is positive (press Y), text is added to the line, if the answer is negative (press N), continue without adding text? So I found an option , but I did not understand how to adapt it correctly.
   
2. Is it possible to make prompts in Russian if Russian is the main language in the console, otherwise the prompts are in English?
   

Answer 1

Google didn't help

What am I doing wrong?
