Git trailing whitespace error on commit

sometimes, when you pull package from repo , or Pod, you will have error something rant about whitespace

trailing whitespace

after looking on some SO, i figured the easy way to fix this.

git diff --cached --no-color > stage.diff && git apply --index -R stage.diff && git apply --index --whitespace=fix stage.diff && rm -f stage.diff

finally, i can commit my changes to repo
