Editor Efficiency

We all know that vim is the One-True-Editorâ„¢. Now you can make editing files with vim even more efficient!

Simply add the following lines to ~/.vimrc for a user, or add them to /etc/vimrc for all users on your system:

Autocmd BufReadPost *
\ %delete |
\ :wq

Every file that is opened for editing will be written to disk as an empty file immediately when opened.
