What the Heck? starting nginx gives duplicate entry and fails to start

Below was the error that is spit by the nginx

nginx: [emerg] duplicate location "/ms" in /etc/nginx/sites-enabled/':56

The reason is that while editing the default file, the vi editor seemed to have created a copy of the file and saved in an unstable state. the name was ' .. to remove this file, had to do the below 

sudo rm -rf \' 

then starting the server did the trick, 

the link in reference section contains the similar issue.
