title: javascript (spidermonkey) how does one run a linux command from js shell?
body: <p>I'm stumped and feeling stupid. I've tried every search combination I can think of to figure this out. It seems simple, but being new to javascript I'm not seeing anything helpful in my search for examples or demos.
  I'm looking to use a script like I would a python or perl script to run a simple linux command. The interpreter is up and running, so I'm just looking for server-side js resources for help in learning more about js. I've found lots of helful examples if I want to do these types of things in a browser - but I don't want to use the browser.
  I couldn't find a query like this on the site (though I'm sure I'm not asking the right way) so If this is indeed a redundant post feel free to close and point me in the right direction.</p>
