Do you want to understand how Linux works in the real world? From basic Linux commands to creating scripts, this course will teach you all.

The course starts with an introduction to Linux, explaining its shell, terminal, and commands. You will also learn the process of installing Docker and creating a Linux container. Once the setup is ready, you will become familiar with the Linux processes and discover the role of data streams and piping. Moving along, you will learn how to manage files and directories and learn the common search operations used in Linux. Next, you will learn the techniques to compress and sort files and gain a good understanding of user management. Towards the end, you will learn to create executable scripts, grasp networking concepts, and get an overview of environment variables.

By the end of this course, you will be able to perform basic and advanced Linux operations.

What You Will Learn

  • Create new directories and files from the shell using Linux commands
