Skill UI

A comprehensive workflow bundle designed for system administrators and developers. It guides users through the entire lifecycle of system management and shell scripting across Linux, macOS, and Windows. Key phases include environment assessment, writing robust Bash scripts, advanced debugging techniques, linting with ShellCheck, and rigorous test automation using Bats, ensuring scalable and reliable automation.

This skill provides expert guidance on writing highly portable shell scripts that adhere strictly to POSIX standards. It teaches users how to avoid shell-specific extensions (like advanced arrays, specific conditionals, or GNU features) to ensure maximum compatibility and robustness across diverse Unix-like systems (Linux, BSD, Solaris, etc.). Ideal for critical infrastructure scripting and environments requiring extreme cross-platform reliability.

This curriculum covers foundational exploitation techniques essential for binary security analysis. Users will learn to control program execution flow, including overwriting EIP/RIP, constructing ROP chains, implementing ret2libc, and shellcode injection. It provides practical, hands-on exercises on stack overflows and heap manipulation in a controlled Linux environment, establishing the core primitives needed before tackling modern mitigation bypasses.
