Ever need to debug something with you Vim config or ever wonder if your favorite Vim trick is available in stock Vim? There’s a simple way to load vim without any plugins:

$ vim -u NONE

This will open vim without your .vimrc and with no plugins enabled. It’s stock Vim with no customization whatsoever.

There are other ways to open vim loading just .vimrc or just plugins and the Vim documentation has a simple chart to show them:

Argument Load vimrc files? Load plugins?
(nothing) yes yes
-u NONE no no
-u NORC no yes
--noplugin yes no
