Course Description:

'' This course provides insight into the advanced topics for handling and manipulating data streams on UNIX/Linux machines. We will start with an advanced view of using the shell efficiently for data manipulation. Over two days will be devoted to exploring Regular Expressions, as well as in-depth analysis of the advanced sed and awk features. A full day is dedicated to an introduction to the Perl programming, which is such an important and portable programming environment these days.
The course is aimed primarily at the accomplished system user, familiar with scripting, who needs to enhance their knowledge and ability of efficient data manipulation techniques.



Prerequisites
Delegates must have good experience of using UNIX systems, and ideally of developing automated solutions using shell scripting. Familiarity with basic data manipulation tools (e.g. grep), basic regular expressions, and principles of scripting is essential.
Typically, the prerequisites can be met by attending the Multi-Vendor UNIX Fundamentals course followed by the Multi-Vendor Korn Shell Programming course.


Delegates will learn how to
At the end of this course, you will be able to:

Improve the efficiency of shell scripts
Be fully conversant with the advanced Regular Expression features
Use advanced features of sed, such as tagging, grouping, looping , etc
Understand the purpose and the flow of operation of awk
Use awk’s programming features, including decision making constructs, loops, etc
Appreciate the power of Perl in platform-independent environments
Use Perl’s basic ‘magic�variable types, characters, program structure and flow control constructs in simple administrative and reporting scripts
Understand the differences in the three main tools discussed, and make an informed choice of which tool is the most relevant for the task in hand
