This article does a good job of calling attention to the pattern.

If you work in powershell you can start out in the terminal, then when you've got whatever you need working you can grab the history (get-history) and write it to a file, which I've always referred to as a `sample`. Then when it becomes important enough that other people ask me about it regularly I refactor the `sample` into a true production grade `script`. It often doesn't start out with a clear direction and creating a separate file is just unnecessary ceremony when you can just tinker and export later when the `up-enter' pattern actually appears.
