Red Hat Enterprise Linux Survival Skills Series
Absolute System Essentials
COURSE DESCRIPTION
This series teaches the basic working environment of an RHEL (Red
Hat Enterprise 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 Desktop
Environments (KDE and Gnome).
The courses are specifically for RHEL on any supported hardware
platform.
COURSE OBJECTIVES
Each participant will be able to use 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. Environment control via KDE/Gnome
graphical utilities will also be shown. Day-to-day system
administration functions are also shown by commands and graphical
interfaces.
COURSE SESSIONS OVERVIEW
The sessions are oriented in a layered approach: skills and techniques
shown build upon the previous set. Each of the first three Skills
sessions are one (1) day in duration. The overall goal is to have each
participant at a functional (user and scripting) level with RHEL at
the end of the course.
