Part 1: Getting Started with Bash Shell Scripting

In this part, you will establish a solid foundation in Bash scripting specifically tailored for pentesting. Beginning with setting up a proper hacking environment and configuring the Bash shell, this section progresses through essential file and directory management techniques needed for security assessments. You will master core programming concepts, including variables, conditionals, loops, and arrays, before diving into pattern matching with regular expressions – a crucial skill for parsing security tool outputs. The section then advances to function creation and script organization, ensuring you can build maintainable, professional-grade security tools. Moving into networking fundamentals, you will learn how Bash interacts with network services and protocols. The section concludes with parallel processing techniques, enabling you to develop efficient scripts that can handle multiple tasks simultaneously – an essential capability for large-scale security assessments. By the end of Part 1, you will have all the fundamental skills needed to begin writing sophisticated security-focused Bash scripts.
