The "script" of input to the program in question
may be done with "here files", e.g.,

program <<EOF
EOF
... should send a single newline to "program".

Or use the "printf" command ( /usr/bin/printf ) and pipe it
to the command you're running:

     printf "\n" | program

Just say   program </dev/null  for a null input.

... and so on.

HTH,
