How to force symfony 2 assetic:dump save only conc

问题:

I already have all needed js files in web folder, when I use assetic:dump command it produces concatenated file and copies all other files two the same directory. How can I avoid this?

code in twig template:

 {% block headerscripts %}
    {% javascripts output='assetic/vendors_header.js'
        'vendor/jquery-1.10.2.min.js'
        'vendor/html5shiv.js'
    %}
        <script src="{{ asset('assetic/vendors_header.js' ~ assets_version) }}"></script>
    {% endjavascripts %}
{% endblock %}

You added in a comment:

in dev environment. when i use "assets_url" i get all script separetly in browser instead o one compiled gifile

That's the expected behaviour in dev environment: files are not concatenated in order to ease debugging.

In the dev environment, each file is still served individually, so that you can debug problems more easily. However, in the prod environment (or more specifically, when the debug flag is false), this will be rendered as a single script tag, which contains the contents of all of the JavaScript files.
