Vi/Vim prompts the worker who has no permission to save

Sometimes, when we use Vi/Vim to edit a file, if we do not notice the File Permission, the following error may be prompted when we finally save the file. If the user is forcibly exited, the current changes will be lost. I will share with you a method that does not need to exit and save the file.

1. In the Vi/Vim Editor, enter the colon and enter the following command:

%! Sudo tee %/dev/null

2. Enter the sudo user password:

3. After the switch is successful, enter the uppercase L key after the prompt.

4. After the file is saved successfully, enter q to exit.

Note: This operation requires that you can use the sudo command. If not, edit the sudo configuration file.
