Course Description :

This Shell Scripting course is valuable for anyone who wishes to become a "Power User" of linux at the command line. It will improve the productivity of system administrators, developers, network and database managers, in fact anyone who uses linux regularly.Fundamental linux/Unix commands are covered. Text file manipulation utilities e.g. sed, awk, grep, and regular pattern formation are covered. You will learn the constructs of scripting i.e selection, iteration, variable and file handling using the BASH Shell.

Intended for :

Anybody who wants an indepth understanding of the Unix O.S. by being able to read and modify the start-up scripts etc. Also, operators who may be new to programming and wish to become involved in controlling Unix OS. through scripts. Shell scripting is an excellent foundation for those who work in the role of Test Engineer, Technical Support, Unix/Linux Administrator, or Web Developer.

Prerequisites :

Experience of JavaScript, or HTML or any other scripting or programming language would help. However, if you have been working on the Operating Systems and have experience of using the Command Line Interface (CLI) to Linux, or another OS, you will benefit greatly from learning Shell Scripting.
