Automatically answer input prompt of an exe started within a windows batch

I have an InputPromptAutomation.exe that prompts for a user input when started and closes if the user input is s:

C:\>AutomateInputPrompt\InputPromptAutomation.exe
Input 's' to stop the application:
s
C:\>

My Problem: I want to automate the startup of the .exe, such that I can start it by double-clicking a StartInputPrompt.bat. How can I automatically pass the s input, such that InputPromptAutomation.exe starts AND exits upon executing StartInputPrompt.bat?

echo s | AutomateInputPrompt\InputPromptAutomation.exe

Here's an example of piping Dir into a new CMD instance

Echo dir | cmd /k

Put S then Enter in a file.

AutomateInputPrompt\InputPromptAutomation.exe < file.txt

Here's an example of doing a dir then a Type c:\windows\win.ini

File.txt (remember to press enter after the last line). This IS NOT a batch file (even though it is identical to one because I'm use CMD as a sample program).

dir
type c:\windows\win.ini

Then type

cmd /k < file.txt

This assumes the program is reading from StdIn, as most, but not all console programs do. EG when you see Press any key to continue the program is NOT reading stdin.

Start is an internal command name. Do not name batch files start as it will cause problems under some circumstances.
