Trailing whitespace can be a real pain - especially when diffing changes between two versions of a file. Fortunately for vim users, there is an easy way to eliminate unwanted trailing whitespace without having to think about it.

Your .vimrc file is typically located in your home directory. So you can edit it by typing:

vim ~/.vimrc

Then adding the following line to your .vimrc will ensure that every time you save a file (:w), it will remove all trailing whitespace.

autocmd BufWritePre * :%s/\s\+$//e

Trailing whitespace will now be removed from the file when using the Vim editor.
