Hello everyone, my name is Razvan, I'm a senior back-end engineer and online instructor.

In this course I will teach you how to become a master of the Unix shell.

Although it’s true that the graphical user interface dramatically simplifies our personal day to day use of computers, to navigate through folders, edit files and install software… the shell, beyond providing an outstanding level of control over the operating system, still proves to this day to be the best and sometimes only option to perform most of our tasks as developers.

Indeed, using a shell is, often the only way to run certain programs or to connect to distant computers, as tools like Git or Linux servers don't provide a graphical interface.

This course is going to cover a lot of topics and concepts but no worries, I don't assume you already know what a terminal, a command-line or text editor is — so we’ll go through all of it, step by step.
