use 'Components' to access chrome authority. To do so, you need to add a
line somewhat like the following:

  const {Cc,Ci,Cu} = require("chrome");

Then you can use any shortcuts to its properties that you import from the
'chrome' module ('Cc', 'Ci', 'Cm', 'Cr', and 'Cu' for the 'classes',
'interfaces', 'manager', 'results', and 'utils' properties, respectively. And
`components` for `Components` object itself).

const {Cc,Ci,Cu} = require("chrome");

var path = "/usr/bin/bash"
var args = ["-c", "echo 'Hello, Zhopin.' > /tmp/lor-test-again.txt"];

var file = Cc["@mozilla.org/file/local;1"]
             .createInstance(Ci.nsIFile);
file.initWithPath(path);

var process = Cc["@mozilla.org/process/util;1"]
                .createInstance(Ci.nsIProcess);

process.init(file);
process.run(true, args, args.length);
