Enhancements and Error Handling for Script Generation

[Fyroo]

It's a handy tool. However, I've noticed that it lacks proper error handling, which could make it more user-friendly. In my opinion, we should add checks to validate user inputs, verify the existence of directories, and handle potential errors, such as invalid script types or existing files. This will help users understand and resolve issues when running the script. I'd appreciate your thoughts and would like to contribute to this. Thanks
