Red Hat Linux Essentials


			COURSE DESCRIPTION

    	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.

			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.
