Chrome: Call Javascript function from (system) command line?

Question

I need to call a Javascript function from a website running in Google Chrome / Chromium from the command line.

Is there any possibility to get access over the developer tools from outside via command line? Is there an extension I could use to execute code?

The most convenient way would be to have access to the Chrome developer console from the command line.

Edit:

To make it more clear: Let’s say the website I’m on has this function defined:

function hello() {
  alert("hello");
}

I would like to call this function, but I don’t have access to the developer tools in Chrome. I can only access the Mac OS X Terminal (via SSH). It’s a setup in a gallery without keyboard. Some kind of pipe may be needed.

Your mean command line (CMD) in windows? why you not use google console? — Mohammadreza Yektamaram

What are the downvotes for? Maybe it's an odd question, but I wouldn't call it unclear or lacking research effort. It could benefit, greatly, from a "why." — T.J. Crowder

@Cerbrus There are all sorts of options when launching Chrome from terminal. It's possible that's really what OP wants. Also note that "terminal" is a tag here. — Paul Roub

I am talking about Terminal in Mac OS X. Basically I would like the code I enter there, e.g chrome-pipe alert("hello") to be executed in the developer tools console (in this case resulting in a popup). — Pwdr

@Pwdr: Why? You seem to have the dev console open already. Why not enter your code there? — Cerbrus

After some more research I found crconsole, which can be used to execute code in Google Chrome.

Chrome has to be started like this:
open -a "Google Chrome" --args --remote-debugging-port=9222

The command line utility chrome-cli can do this.

Using your code example:

chrome-cli execute '(function hello() { alert("hello"); }())'
