Default [Q] SL4A: Accessing Linux Shell from javascript

Hi everybody!

I recently bumped into SL4A.

For automating some things (wake up and send to sleep my NAS, mount it as local drive) from my android tv box its perfect.

The things i want to automate can be done via Linux shell commands and i would like to implement these functions with a nice GUI in HTML and Javascript.

In Python you do it with os.system i believe, but the problem is, that i am a very experienced, HML and Javascript programmer, but have no clue about Python.

So is there a way to acces the Linux shell directly from javascript or do i have to write a kind of python interface to connect from javascript to the shell?
