1. 为什么用:x而不是:wq：https://til.hashrocket.com/posts/2fdb6afb66-difference-between-wq-and-x#:~:text=The%20%3Awq%20command%20is%20used%20in%20Vim%20to,but%20write%20only%20when%20changes%20have%20been%20made.
2. 为什么用cp而不是dd：See [1] and [2] for a comparison and perspective on the use of those tools and why dd may be the least adapted one.
