Open a file or url in the user's preferred application.
var open = require("open"); open("http://www.google.com");
open taks an optional argument specifying the program to be used to open the file or URL.
npm install open
xdg-openscript from freedesktop.org
The same care should be taken when calling open as if you were calling child_process.exec directly. If it is an executable it will run in a new shell.
