The training provides an understanding of the processes in a Linux system, from the boot process to the system in operation. It covers fault diagnosis in the test field and in support. You learn how to localize and eliminate problems using the operating system tools and standard open source tools.

The required knowledge for handling the Linux Shell is discussed.

The training makes sure that attendees can benefit from their new knowledge when working with embedded as well as with standard Linux systems.
