Linux Shell Scripting Bootcamp

By: James K Lewis

Overview of this book

Linux Shell Scripting Bootcamp is all about learning the essentials of script creation, validating parameters, and checking for the existence of files and other items needed by the script. We will use scripts to explore iterative operations using loops and learn different types of loop statements, with their differences. Along with this, we will also create a numbered backup script for backup files. Further, you will get well-versed with how variables work on a Linux system and how they relate to scripts. You’ll also learn how to create and call subroutines in a script and create interactive scripts. The most important archive commands, zip and tar, are also discussed for performing backups. Later, you will dive deeper by understanding the use of wget and curl scripts and the use of checksum and file encryption in further chapters. Finally, you will learn how to debug scripts and scripting best practices that will enable you to write a great code every time! By the end of the book, you will be able to write shell scripts that can dig data from the web and process it efficiently.

About the Reviewer

Thushara Jayawardena is a very strong asset in software development as well as in the software service industry with more than 15 years of experience in systems administrating. That experience has contributed to this book. The main responsibility of the current day job is performance engineering for a leading European ERP software provider. It translates to system configuration and installations, followed by end-to-end automated performance testing. Scripting is an integral part of all these components.

His spare time is spent partly developing a user guide for tourist attractions for Android and IOS devices. The cloud backend for the solution comprises Mongo Cloud DB services and Heroku app dynos, run on Nodejs. Thushara also spends time with systems on chip devices such as Raspberry Pi and Arduino-like boards. Here, the focus is on IOT-type solutions.

Thushara is a loving father and husband who values his family very much and makes sure homebrewing doesn't come between him and family. He's been living nomadic since 2007, or rather migrated to Sweden with his family and moved around a bit in Sweden, and currently is living south of the beautiful port city of Gothenburg. He enjoys Scandinavian life, simplicity, and respect very much and is keen on improving his skiing skills during the winters up in the Swedish mountains. He has also worked on Raspberry Pi Android Projects.
