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 will concentrate on Red Hat Enterprise Linux
(RHEL), version 6 (all update levels).
This course is the equivalent of Red Hat course 124, with additional
shell scripting topics.
Linux Training Prerequisites
This course is considered to be the basic Red Hat 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 RHEL 6 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 RHEL6 system will also be shown.
