Brief introduction:

Vim editor is a standard editor in Linux/Unix system, an indispensable editing tool in Linux system, and an upgraded version of vi editor. The use of vim editor will also be involved in the use of Mac system terminal functions.

Most Linux systems come with a vi editor. If you need to install vim yourself, the instructions are as follows:

Sudo apt install vim

The Mac system comes with a vim editor, or you can install it using brew:

Brew install vim

The terminal inputs the vim+ file path or file name to create or open the vim file.

Three modes of vim:

There are usually three modes of vim: general mode, insert mode, and last line mode. This article introduces common operations in general mode.

General mode:

General mode is also called normal mode or command line mode. Whatever it is, this is the pattern you see by default when you enter the vim file. Here, you can use the up and down keys to move the cursor, delete, copy and other operations to deal with file data, but can not insert data freely.

Beginners should not be frightened by the interface which is full of symbols and seems to have no response to anything. in fact, it has its own unique mode of instruction operation.

(note: after creating an empty file, you can press [I] to enter INSERT mode for free input, which is convenient for practice. After the input is completed, press [ESC] to exit INSERT mode and return to general mode)

Copy and paste:

1. By character:

Enter the character [v] (lowercase) in general mode to enter VISUAL by character selection mode, move the cursor through [h, j, k, l] or direction keys to select the string to be copied, then press y to copy, move to the target and press p to paste.

2. By line:

Enter the character [V] (uppercase) in general mode to enter VISUAL LINE select by line mode, select the line to copy, press y to copy, press p to paste

3. Press the block:

Enter the character [ctrl+v] (uppercase) in general mode to enter VISUAL BLOCK by block selection mode, select the block range to copy, press y to copy, press p to paste
