< span style="white-space:normal;">Vim editor commonly used commands and functions:

[vi editor] visual interface visual interface vim enhanced version; full-screen mode editor
In the command state, use == (double-press=twice), Or use n== for multiple lines (n is a natural number) to automatically indent the following n lines from the current line.
You can try to indent the code arbitrarily and then use n== to typeset, which is equivalent to the code format in the general IDE.Use gg=G to typeset the entire code.
vim +15 file is directly on line 15
vim + file to the last line of the file
vim +/mode file is opened and positioned to the beginning of the line matched by the pattern for the first time
ctrl-g can display the current cursor position
Edit mode [command mode]; input mode last line mode
mode conversion: edit->input
i switch to input mode before the character where the current cursor is located
a input after the current cursor
o Create a new line below the line where the current cursor is located, and switch to input mode
I Switch to input mode at the beginning of the line where the current cursor is located
A Switch to the end of the current line
O At the current line The previous line of the is converted to input mode
Enter->Edit esc; Edit->Last line: Last line->Editing esc sometimes requires 2 consecutive esc (with input last line command)
Last line mode Middle: 10d 10, 20d delete rows.You can also directly use:! Ls to execute commands.
Close the file: :w! Forcibly save; only root has the right to execute this; :x is equivalent to :wq save and exit.
Exit in edit mode and press ZZ directly to save and exit.
Move the cursor: hjkl.You can add a number;
w moves to the beginning of the next word; e jumps to the end of the current word or the end of the next word
b jumps forward to the beginning of the word, w, Both b and e support adding numbers in front.
Jump within the line: 0 and ^ both indicate jump to the beginning of the line; 0 jump to the absolute beginning of the line; ^ jump to the first non-blank character.$End of line
Jump between lines: how many lines to jump to by adding a number before G, gg jump to the first line, G to the last line
Jump in the last line mode: just press Enter for the line number.
[Flip screen]ctrl+f,b,u,d
[Delete a single character] x #x delete the following # characters
The d command combined with the jump command can operate multiple places.Such as d plus $/0 can be deleted to the beginning of the end of the line.dw, #d,de,db,dd,#dd,
The last line mode 10,20d deletes 10 to 20 lines..,+5d Delete the 5 lines after the current line.
.The current line $ last line + # the next few lines; $ -1 the last few lines.
