VIM Editor | VIM Introduce

Learning VIM will make it your last text editor to use. There is no better text editor, it is very difficult to learn, but incredibly useful.
I suggest the following four steps: ①. Survival; ②. Feeling good; ③. Feeling better, stronger, faster; ④. Using VIM's superpowers.
The learning curve of VIM is quite steep, so if you see a bunch of VIM command categories at the beginning, you will definitely lose interest in this editor.
vi(vim) is a very commonly used editor on Linux, and many Linux distributions come with vi(vim) installed by default. vi(vim) has many commands, but once you master them, it will greatly improve your efficiency. vi stands for "visual interface", and vim is short for vi IMproved (an enhanced version of vi).
