If you want to script interaction with a program expecting human input, bash and most other shells are very bad at that. Pipes are poor substitutes for the interactive terminal the program is obviously expecting, they tend to deadlock with each process waiting for the other and no way to notify each other of said fact.
If your interaction is any more complicated than typing one number and hitting enter, you might look into the expect language, which is designed for these sort of problems. It will allocate a PTY which allows it to control the program it's communicating with asynchronously without all the piping and redirection.

COMMAND-NOT-FOUND(1) http://en.opensuse.org/Sco COMMAND-NOT-FOUND(1)
NAME
command-not-found - A command-not-found handler
SYNOPSIS
command-not-found {binary_name} {repository}
ARGUMENTS
The following arguments are required:
binary_name
The name of binary you are looking for.
repository
The name of repository for search. For most cases, use zypp
DESCRIPTION
command-not-found handler is designed to tell users which package contains a missing command.
The handler is integrated to bash(1) and zsh(1) shells and is not necessary to call it directly. Just type a name of the command in your
favourite shell and you'll get a result.
If you consider c-n-f handler useless, just add unset command_not_found_handle to your profile or remove the command-not-found package.
Handler doesn't call the command-not-found binary directly, it only prints info about it. If you want to invoke it automatically, just add
export COMMAND_NOT_FOUND_AUTO=1 to your bash profile.
EXAMPLE
: NORMAL USAGE
For example you want to try blender, because you have heard that is an amazing program. So just type blender in shell:
$ blender
You get the following output:
The program 'blender' can be found in the following package:
* blender [ path: /usr/bin/blender, repository: zypp (openSUSE 11.1-0) ]
Try installing with:
sudo zypper install blender
bash: blender: command not found
