Fundamentals of Unix: Shell/awk Scripting
Solaris Training Overview

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.

Solaris Training Prerequisites

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

Solaris Training Course duration

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

Solaris Training 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.
