Summary of new usage of vi of vim under linux

I've been using the vi editor for several years, but I still haven't used some practical usage. After listening to the introduction of linux in python video today, I still learned some new tricks

1.: set nu displays line number

2. gg--to the beginning of the document

3. G-----to end of file

4. u----Undo operation

5. Ctrl+r--Redo

6.:/better Enter, find the word that matches better, and press n to find the next 1

7.: s/better/dog Enter and replace the first better in this line with dog

s/better/dog Enter and replace all better in this line with dog

% s/better/dog Enter, replace all better in this document with dog

8. vi -O2 file1 file2

Use one screen to display file1 and file2 files at the same time, which is convenient for editing. Press ctrl+w to switch from one file to another file window.
