advanced shell techniques

Linux Bash Shell scripting is an incredible resource for automating tasks, managing systems, and much more. It is equipped with a range of tools and features that allow users to control how programs intercommunicate and manage data. Among these capabilities, I/O (Input/Output) redirection and co-processes play a fundamental role in advanced scripting and task automation. In this article, we’ll dive deep into these features and also provide guidance on how to ensure you have all the necessary tools, regardless of your Linux package manager.
