[Original] about setting vim display line number in Linux

1. Change all account configurations

Change/ETC/VIMRC directly
Vim/etc/vimrc
Add set Nu at the end of the VIMRC file
Wq exit.

This way, no matter which account you use to log in, Vim opens and displays line numbers

2. Configure the environment for the current user

Locate the current user's VIMRC file. If you do not have this file, you can create this file.
Vim ~/.VIMRC
After opening the file, add the last
Set Nu
Wq exit.

Open with Vim again to display line numbers

When the above method is set, the next time the Vim editor is started, the line number will be displayed automatically.

3. Set line number for each manual (not recommended)

Enter VIM

Input ': Set Nu '

Immediate, show travel number
