suggestion - expose commands directly (`ls` instead of `shx ls`)

[akashmugu]

exposing commands directly (e.g. ls) along with (or instead of) via shx (e.g. shx ls) will make adding and removing shx extremely easy and literally a one line change

npm i -D shx

many small teams still use *nix commands directly in scripts if all the members use *nix. if a newly joined team member uses windows, just add shx to the devDependencies and magic, it all just works

let me know if makes sense. i'd be happy to create a pr

Not a high priority, as this is already offered by https://github.com/dthree/cash.
