How to run bin/lint

I have a new mode (SAS) that I’m almost ready to do PR for. I know I need to run the distributed linter in bin/lint but I’m not sure how to accomplish that.
I’m looking for a one-liner (hopefully it is that simple).

I tried ./lint ../mode/sas/sas.js

but it threw the following message:

    throw err;

Error: Cannot find module 'blint'
    at Function.Module._resolveFilename (module.js:325:15)

You have to install the dependencies.

npm install
