By: Bogdan Vaida, Petru I»ôfan

Overview of this book

Websites, online services, databases, and pretty much every other computer that offers public services runs on Linux. From small servers to clusters, Linux is anywhere and everywhere. With such a broad usage, the demand for Linux specialists is ever growing. For the engineers out there, this means being able to develop, interconnect, and maintain Linux environments. This book will help you increase your terminal productivity by using Terminator, Guake and other tools. It will start by installing Ubuntu and will explore tools and techniques that will help you to achieve more work with less effort. Next, it will then focus on Terminator, the ultimate terminal, and vim, one of the most intelligent console editors. Futhermore, the readers will see how they can increase their command line productivity by using sed, find, tmux, network, autoenv. The readers will also see how they can edit files without leaving the terminal and use the screen space efficiently and copy-paste like a pro. Towards the end, we focus on network settings, Git hacks, and creating portable environments for development and production using Docker. Through this book, you will improve your terminal productivity by seeing how to use different tools.

If we open this file inside our browser, we can see the page content:

Clicking on the button generates a javascript error. It is telling us that we want to do a cross-origin request, which is not allowed by default by the browser. This is to prevent cross-site scripting attacks. What we need to do in order to test our javascript code is to serve this file in an HTTP server.

In order to start an HTTP server in the same folder as the file, we type the following command:

python -m SimpleHTTPServer

This is a basic Python module that opens port 8000 on localhost, serving only static content (so, no, you can't use it for php). Let's open the address in the browser:
