How to edit global file installation

I just ran this line of code

npm install -g csslint

CSSlint seems great but I want to add the ability to prettify my css by putting in custom code. The goal is to have a command line interface where I can format my css before pushing the code to the server.

"-g" stand for installing globally correct?

Where does this library get installed to and how do I access it? I thought it would be in my user/local/bin but I couldn't find it.

Thanks!

use npm root -g to see where modules get installed. If you want to use it in your code using require() then install it locally i.e. without using -g option. More details here https://npmjs.org/doc/faq.html

I believe it's going to depend on your npm settings, but my global npm binaries are in /usr/local/share/npm/bin
