RHCSA Rapid Track Course

Linux Training Overview

This course presents the working environment of a RHEL 6 system. It introduces commonly required operations that can be performed by entering commands interactively in a command terminal, along with functions available in the K Desktop Environment (KDE) and Gnome. This course will concentrate on Red Hat Enterprise Linux (RHEL), version 6 (all update levels).

This course helps to prepare for the RHCSA examination.
