How do you enter something at a DOS prompt Programmatically?

Question

I have program, that must interact with a DOS program before my program can continue what it is doing. I\'m trying to avoid my user from having to interact with this dos pro

Answer 1

You can pipe in a 'y' character into the program like so:

echo y | executable.exe

Multiple lines can be entered like so:

(echo y
echo n) | executable.exe

...which will pass first 'y' then 'n'.
