Solution 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

Solution 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.

Solution 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');

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

  Why don't you write it in bash?

  Yes, that was the first option, but someone suggested me to use javascript, so thats why I'm wondering if it is possible or not. :)

I don't need a browser emulator. All I want to do is run a javascript file (using an interpretor) that runs some linux commands. Is it possible to do this? And also I would prefer not to depend on Java, because my javascript file should make some installations on my linux machine. I don't know if my questions is clear, but I was suggested to use javascript for doing this, and I don't realy know how.

Yes, I need to run something like system('rpm -i myapp.rpm'), but directly from Javascript, because I can't depend on other languages, like C++ or Java.

Since JavaScript is an interpreted language, you need an interpreter. For the interpreter to run, you need some other language.

"For the interpreter to run, you need some other language." No, you don't need another language. You just need a JavaScript engine. V8 (Google's JavaScript engine), for instance, is a compiled executable. You don't need another language runtime (Python, the JVM, perl, whatever) to run it.

Which is what I meant: You need V8.
