Bash is great, but sometimes we need the power of a more robust programming language to accomplish our goals. In this lesson, we’ll look at how we can integrate node.js within bash to send data to and from a node.js script. First we’ll look at how to do quick one-liners at the shell using node's -p (print) option. Then we'll write a node.js script that accepts parameters from the shell to check the value of a query string. In node.js, we can use the process object to interact with command line arguments and stdio.
