UNIX and Linux provide a rich set of utilities to enable developers to streamline tasks and maximize productivity. To realize the full power of your UNIX/Linux system, you need to choose the right tools and use them in the right combination. Through extensive in-class hands-on exercises, you gain the knowledge and skills to adapt the UNIX environment to your particular needs. UNIX, unlike other operating systems, was designed to be a programmer's toolset. As such it contains a wealth of little "gadgets" that can make the operating system much easier to use, if you know the resources available to you. The UNIX tools and utilities we cover in this course include the shell, commands, filters, and even languages such as AWK.

This course teaches you how to unlock the hidden processing power in your UNIX system. UNIX contains many tools and utilities that can help the user automate tasks and improve productivity. This course provides an overview of these topics, giving you valuable perspective on a huge and unwieldy area that could take months or years to learn on your own.

By the end of this course, delegates will be able to:

· Become an expert builder and user of UNIX/Linux tools and utilities

· Perform complex search strings using regular expressions

· Explore Extended Regular Expressions with GREP, SED and AWK

· Employ text filters to manipulate text and data

· Build shell scripts to automate routine tasks

· Process structured data with AWK

· Learn how to form powerful regular expressions for searching text

· Learn how to combine filters for text processing

· Learn how to refine the output of commands with SED

· Learn how to perform complex text selection and manipulation with AWK

· Learn how to automat simple, repetitive tasks using shell scripts

· Learn how to write shell scripts to customize UNIX tools

System administrators, database administrators, programmers, technical support staff-or anyone who wants to maximize the power of their UNIX system, those who want to maximize the power of their UNIX/Linux system, anyone who want to become UNIX power users and exploit the advanced features and facilities of UNIX
