Stimulate ENTER key from another shell script

Question

I have two shell scripts one.sh and two.sh

I want to execute two.sh from one.sh. Below is the code :

#!/bin/sh
sh /home/ubuntu/two.sh

The next step ( where I got stuck). There is one point in two.sh when the user have to press enter to continue . Next after entering, I need to give the desired directory. I want to stimulate both the steps from one.sh

Any suggestions ???

Answer 1

So it worked by using printf, if you know exactly how many y your script is expecting you can do it like this:

$ printf 'y\ny\ny\n' | ./script
