`src/**/*.js` doesn't match all the .js files in src folder

[CodinCat]

#macOS Sierra
node.js v6.9.1
standard v8.6.0

Since I only want to lint the src folder, I have the follow npm script, which I expect should match all the files under src
"lint": "standard src/**/*.js --fix"

but I found that this command doesn't match files which are more than 2 depth.

- src
    - dir1
        - dir2
            - file.js  <-- this file will not be handled by standard
        - foo.js
        - bar.js
    - index.js

Not sure if is a bug, or it's an expected behavior and I'm doing something wrong,
thanks.

Ok I got it

I should quote the path in npm script

this will work
"lint": "standard 'src/**/*.js' --fix"
