Good questions are based on research on the subject of the question. Once that is done, you have at least a clear assumption of the options you have, and you can ask the way to achieve your goal and where your assumptions may be incorrect. Your question then is based on clear information, either correct or not, and an answer can be given accordingly.
You are doing it exactly the opposite way. You start with a vague picture of what you want to achieve, not having put any effort in what are technically the options.
As a result, you are asking us to join you in your attempt to create weird solutions, based on a lack of basic knowledge. While doing do, you constantly give us contradictionary information, [like here][1], in the question: "I don't want a script", in a comment: "a script doesn' matter" and so on.
Finally, repeating the question "so others users will notice", and "reposted my question", "may seem like a duplicate"?? completes the mess. [1]: How to make a command execute once a certain command terminates?
