How to populate the command line interface?

Question

I have to automate the installation phase of an outdated system because I don’t want to put in more effort again and again when I want to install it. During the installation process on a Linux terminal, I have to answer some questions regarding basic configurations. In fact, it is easy to automate shell commands by placing them in a batch file as follows:

bin/startServer destination/sub_v1
bin/startAdminInterface
....

However, I do not know how to automate answers to specific questions, such as:

Enter the server IP address: 
Enter the email of the contact person:
Would you like to disable UDP services?(y/n) [n]:
....

Is there any tool or programming language that can handle this situation? or is there a way to pass responses as parameters in a batch file?

Thanks in advance.
