Red Hat System Administration I

Linux Training Overview

This course presents 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 GNOME Desktop Environment . This course will concentrate on Red Hat Enterprise Linux (RHEL), version 8 (all current update levels).

Linux Training Prerequisites

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

This course is the first of two courses used in preparation for the examination to achieve the Red Hat Certified System Administrator (RHCSA 8) certification.

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 RHEL 8 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. Basic administrative features to setup a functioning RHEL 8 system will also be shown
