When calling a grunt task what is the difference between using a single - or double -- for a flag/option as both seem to work.
grunt compile --watch
grunt compile -watch
Also when saving a grunt task you often see --save-dev
I know functionally what this does, but "flag/optionwise" what is the purpose of -dev coming immediately after --save and whats actually happening?
You are asking two different questions. Your first question has nothing to do with Grunt or NodeJS and it is answered here.
The second question, I think you are talking about npm or bower.
--save will add the package to the dependencies object.--save-dev will add the package to the devDependencies object.More details about the difference and when to use each one is here.
