Fundamentals of Unix: Shell/awk Scripting


			COURSE DESCRIPTION

	This course teaches the Unix computer professional (user, systems
	administrator, application/system programmer) the techniques
	needed to develop advanced shell and reporting type procedures
	under Unix.  Techniques in the major shells will be shown.  Note that	    
	all Unix systems support all of the techniques in this course.


			COURSE OBJECTIVES

	Each participant will be able to use Unix shell (common features, Korn 
	(ksh 88 and ksh 93) commands to maintain collections of files, control
	usage of shell command scripts, and generate reports using the
	awk facility.


			COURSE TOPICS

		Shell Scripting Common Features
			Shell environment variables
			User-defined variables
			Substitution of variables
			Looping statement constructs
			Decision statements
			Command substitution in variables
			Using eval
			Handling signals with trap


		Writing Korn Shell Scripts
			Korn Shell environment variables
			User-defined variables
			Substitution of variables
			Command substitution in variables
			Decision statements
			Looping statement constructs
			typesetting variables for output
			typesetting integer variables
			the select construct (for menus)
			using and defining functions
			accessing files' records using pipes
			accessing files' records directly with exec
			special parameter/variable substitutions
			Korn shell parent-child process communications
			defining and using arrays


		Advanced Features in Korn Shell Scripts
			Options processing
			active variables and tied functions
			associative arrays
			creating and using name reference variables 
			techniques comparison to Perl


		Using the awk Utility to Generate Reports
			awk utility calling techniques
			Patterns and actions

			special awk signature lines


			COURSE DURATION

	This course normally requires three (3) days, approximately 50 %
	lecture, and 50 % lab time.
	

			COURSE PREREQUISITES

	This is an advanced Unix course.  It is assumed that participants
	either have attended the Fundamentals course for Sun Solaris, IBM
	AIX, or HP-UX, or have equivalent system time and experience with 
	the interactive shell(s).
