babel-cli not working as expected

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.

Possible duplicate of Babel file is copied without being transformed - loganfsmyth
This is kind of two questions. The first is a dup, and the second is just that when you install locally, you need to run the local version using ./node_modules/.bin/babel. - loganfsmyth
@loganfsmyth can you say us more about this necessitate to use the .bin version of the package please - Webwoman
