babel-cli not working as expected

Question

I had installed babel-cli globally using npm. And I had a script.js file which contains the ES6 code. When I tried to compile that using $babel script.js -o out.js, it just copy all the contains of the script.js to out.js.

As far I concern, it should convert all the ES6 code to ES5.

Even if I run the script.js file without any content, it should show "use strict"; in my out.js. But it shows an empty file. Unable to figure out whats wrong?

Moreover I am unable to understand why "https://www.npmjs.com/package/babel-cli" says to install babel-cli globally where as "https://babeljs.io/docs/setup/#babel_cli" says to install that locally.

When I installed babel-cli locally and try to compile the script.js file it simply shows

'babel' is not recognized as an internal or external command, operable program or batch file.
