Display and hide of vim line numbers

Usually when we use the VIM editor, we need to show and hide line numbers.

Hide line number:

1. First we vim 1.txt (into the document we edit), as below, this is the display line number

2. Click the ESC key and enter: (colon) to complete the effect as follows

3. Enter set Nonumber and press ENTER to complete without line number

If you want to display line numbers after editing, do the same by pressing the ESC key and entering: (colon), entering set number and pressing ENTER, and then displaying line numbers when finished.

After completing the VIM display line number and not displaying the line number, you can continue pressing I key to enter edit mode
