Overview of this book

Shell scripting is a quick method to prototype a complex application or a problem by automating tasks when working on Linux-based systems. Using both simple one-line commands and command sequences complex problems can be solved with ease, from text processing to backing up sysadmin tools. In this book, you’ll discover everything you need to know to master shell scripting and make informed choices about the elements you employ. Get to grips with the fundamentals of creating and running a script in normal mode, and in debug mode. Learn about various conditional statements' code snippets, and realize the power of repetition and loops in your shell script. Implement functions and edit files using the Stream Editor, script in Perl, program in Python – as well as complete coverage of other scripting languages to ensure you can choose the best tool for your project.

Summary


We now have some heavy ammunition behind our text processing and we can begin to understand just how powerful awk can be. Working with real data is particularly useful in gauging the performance and accuracy of our searches. Having begun working with simple Apache entries on the newly installed Ubuntu 15.10 Apache web server, we soon migrated to the larger sample data from a live web server. With 30,000 lines, this file gives us some real meat to work with and in no time we were able to produce credible reports. We closed up the return to the Ubuntu 15.10 server to analyze the Postfix SMTP logs. We can see that we can very much drag and drop the technology that we have previously used into the new log files.

Next up, we stick with awk and look at how we can report on the lastlog data and on flat XML files.
