Javascript interpreter for Linux

Question

Is there a way to run linux commands from javascript that uses a standalone interpreter (something similar with SpiderMonkey, JavaScript shell)?

Answer 1

You could use NodeJS. It has a child_process module that can run arbitrary commands. E.G. child_process.spawn()

When your script is finished you run it like this:

node myscript.js

Answer 2

jslibs is a standalone JavaScript interpreter that runs on Linux32/64 and Windows.
You can easily run linux commands through the libraries provided by jslibs.

Answer 3

It's possible to define JS functions that will call your C/C++ functions that could use system() call, executing some linux commands.

• Spider Monkey's way: https://developer.mozilla.org/en/JavaScript_C_Engine_Embedder's_Guide#Native_functions

• Google V8 is also an option: http://code.google.com/apis/v8/embed.html#accesssors

So you would have

system('rpm -i myapp.rpm');
system('rpm -i myapp2.rpm');

or perhaps

install('myapp.rpm');
install('myapp2.rpm');
