title: Input from within shell script
body: <p>I have a script that calls an application that requires user input, e.g. run app that requires user to type in 'Y' or 'N'.<br>
  How can I get the shell script not to ask the user for the input but rather use the value from a predefined variable in the script?</p>
  
  <p>In my case there will be two questions that require input.</p>
