Book Description – Classic Shell Scripting pdf
Classic Shell Scripting pdf – Shell programming abilities are always in demand. The shell is the key to unlocking Unix’s true capabilities. Unix users and system administrators need shell scripting to easily harness and personalize the full capabilities of any Unix system. Shell scripts allow you to crunch data and automate repetitive activities by combining the most basic Unix text and file processing functions. However, beneath this simple promise lies a hazardous sea of Unix command and standard variants. Classic Shell Scripting was created to assist you in navigating these treacherous seas. Writing shell scripts involves more than just a command-line understanding of the shell language; it also necessitates an understanding of the various Unix programs: why they exist, how to use them separately, and in conjunction with other programs.
- The writers are well-versed in both the best practices for writing outstanding scripts and the pitfalls that can turn your finest effort into a lousy shell script.
- You’ll save hours of time and work by using Classic Shell Scripting.
- Not only will you learn how to develop useful shell scripts, but also how to do so correctly and portably.
- Anyone operating and maintaining Unix or Linux systems needs to be able to program and customize the shell fast, consistently, and portably in order to get the most out of each system.
- Classic Shell Scripting provides you with all of the tools you’ll need to master these vital abilities.
Because each chapter builds on the previous one, the book can be read straight through, however, the aforementioned resources are especially useful when utilizing this book as a reference. It would be tough to search up stuff like how to adjust the field separator in different tools or how to assure case insensitivity if it weren’t for the tables and sidebars. The writers cover a variety of topics throughout the book, but regular expressions, sed, awk, control flow, command evaluation, and file manipulation are covered in depth in chapters 3, 6, 7, and 9. The majority of the remaining chapters are applications of the ideas covered up to that point, and they help to reinforce what has already been learned (though there are pleasant exceptions to this pattern, e.g. the section on crontab in ch. 13, or the material on the Unix filesystem in Appendix B).
