After these days of study, you should know that Linux is a text file dealing with the system, then how to deal with such a system? We have to learn how to create new files, delete files, modify files, and so on, so you need a text editing tool to do these things. And the most popular text editing tool in Linux is vi/vim; This article will give you a detailed account of how to use the Vi/vim text editor under the Linux operating system, a minute to understand Vi/vim's past life.
  
 The first thing we need to know is what is Vi/vim?

The VI Editor is the most basic text editor on Linux and Unix, working in character mode. Because no graphical interface is required, VI is a highly efficient text editor. Although there are many graphical interface editors available on Linux, the functions of VI in System and server management are unmatched by the graphical editors.
  
The VI Editor can perform many text operations, such as output, delete, find, replace, block operations, and so on, and users can customize them according to their needs, which is not available in other editing programs.
  
Vim is a text editor developed from VI. Code completion, compilation and error jumps and other convenient programming features are particularly rich, in the programmer is widely used.
  
  Special
  
Point

  
For VIM already has the basic understanding of you, certainly also wants to know its characteristic! It has three features that the public can understand!
  
Vi/vim is a plain text editor, it is not like Word can be typeset, you can adjust the font size, you can change the font
  
Vi/vim is just a text editing tool that can only manipulate the contents of text
  
VI is a full-screen text editor that will occupy the entire screen when editing text
  
Although it is not possible to adjust the font and size as Word documents do, the advantage is obvious.
  
1. Full keyboard operation, shortcut key combination, so that the efficiency greatly improved
  
2. Quick Start, light and fast
  
3. More expansion, sufficient enough
  
  There are three modes in the Linux vi/vim Text Editor: Command mode, input mode and last line mode. What is the difference between the three models?

  

  Mode
  
Expression

  
Command mode: is the default mode after the Vi/vim editor enters, for example, if you want to edit the file, then you need to enter "I" to make the current mode into insert mode or input mode, so you can edit the text. You can also let users execute commands, such as copying rows and pasting rows.
  
Input mode: As the name implies is to do the input of this article operation, that is, you can make changes to the file operation.
  
Last-line mode: Used to find text, save changes.
  
One of the things we need to focus on is the transition pattern between them, which is not easy
  
Command mode--input mode---Command mode
  
Command mode----last-line mode--command mode
  
Command mode--input mode
  
I:insert, in front of the character at which the cursor is currently positioned, into input mode
  
I: Uppercase I, converted to input mode at the beginning of the line where the current cursor is located
  
A:append, converted to input mode after the current cursor character
  
A: The end of the line at the current cursor is converted to input mode
  
O:open, creates a new row below the current cursor line and shifts to input mode
  
o: Uppercase O, not number 0, creates a new row above the current cursor line and converts to input mode
  
Input mode---Command mode
  
Esc
  
Command mode----Last-line mode
  
:
  
Last-line mode--command mode
  
ESC ESC
