Save a file in vim without root permission

This happens lot of times. You open Vim to edit a system file, do some changes, and :wq. We won’t be able to save a file due to permission issues.

To save a file, simply type the following command.

:w !sudo tee % and enter the password as prompted. Voila.

Add this to your ~/.vimrc file

Edit ~/.vimrc and append the following code: command W :execute ':silent w !sudo tee % > /dev/null' | :edit! Save and close the file. Now, try to edit a privileged file. Now, write a privileged file with custom command :W
