Target Audience

The training is aimed at people who want a quick and clear introduction to the Linux operating system. This includes anyone with a general interest in Linux, anyone who will use Linux, or as a first step for those who will administer Linux systems. The focus is on learning to manage Linux systems via the command line

You will learn

  • What a Linux system is and how to use it
  • Linux architecture and underlying processes
  • The differences between various Linux distributions and UNIX.
  • Using the basic commands found in Linux systems.

Previous knowledge

The course assumes that you have used Windows or MacOS before taking the course. You do not need to have used the command line, written scripts or worked with Linux before. However, the course also works well for those who already have some experience with Linux and programming - you will then be able to deepen your knowledge
