Linux Training : Red Hat Linux Essentials

Red Hat Linux Essentials

Linux Training Overview

This course teaches the basic working environment of a Linux 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 is applicable to all current variants of Linux, although the materials and labs will concentrate on Red Hat Enterprise Linux (RHEL), version 5 (all update levels).

This course is the equivalent of Red Hat course 033, with additional shell scripting topics.

Linux Training Prerequisites

This course is considered to be the basic Linux course. Experience with any interactive system is helpful.

Linux Training Course duration

This course normally requires five (5) days, approximately 50% lecture and 50% lab time.

Linux Training Course Objectives

Each participant will be able to use RHEL5 Bash Shell techniques and commands to maintain collections of files, create files using interactive editor utilities, create and execute basic command procedures, communicate with other users, and tailor the interactive environment to meet their needs.
