Use of the Linux base vim

1. Introduction of VI

basically , VI is divided into three modes:

Command mode

Open a file with VI directly into the command mode. In this mode, you can use [up or down ] keys to move the cursor, delete characters to process the contents of the file, or copy and paste the file data.

insertion Modes (insert mode)

in command mode, enter: [i Ia A o O] any one letter will go into insert mode. This is where you can edit your files.

I: enter before the current cursor is positioned.

I: Enter at the beginning of the current cursor position.

A: Enter after cursor position

A: Enter at the end of the cursor line

O: add a blank line to the next line where the cursor is located

O: Add a blank line to the previous line where the cursor is located

command-line modes (command-line mode)

in command mode, enter [:/ ?] Either way, you can do the command-line mode.

So how do you get out of VI ?

if it is in insert mode, then type " ESC"key, enter

: q! force exit, i.e. do not save exit

: Wq Save Exit

: Wfilename Save File

: x Save and exit

If you are in command-line mode, directly enter ZZ, that is, to save the exit .

2. Vim Visualization mode

To enter v in command mode, manual select Mode is available.

V: The selected cursor is the same as the forward

Once selected, the previous edit commands can be used

3. Open multiple Files

: Next Next

: Prev Previous

: First One

: Last One

For easy comparison, you can use the –o or-o option

Vim–o: Horizontal Screen comparison

Vim–o: Vertical Screen comparison

How do I move the cursor in two files?

Horizontal screen comparison using the "Crtl" +w up and down arrows

Vertical screen comparison using "Crtl" +w left and right arrows

In the same file, you can use a split screen to compare the differences

Horizontal split with "Crtl" +w,s

Vertical split with "Crtl" +w,v
