Here is something that I ran into on several of my computer jobs. I would be asked by my manager to take over a project from a fellow worker. He would zip
or tar
up the files and then give me the archive. I would uncompress it on my system and try to begin the work. But there was always a file missing. It would often take two, three, or more attempts before I would finally have every file needed to compile the project. So, the moral to this story is when making an archive to give to someone else make absolutely sure to copy it to another machine and test it there. Only then can you be reasonably sure that you have included every file.

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.
