R2CLi

R2CLi is a command-line interface (CLI) tool designed to interact with the R2 Framework, a popular reverse engineering and binary analysis toolkit. Developed as an extension of R2’s capabilities, R2CLi provides users with a more streamlined and efficient way to perform tasks such as disassembly, debugging, and binary analysis directly from the terminal. It is particularly useful for security researchers, reverse engineers, and developers who prefer working in a command-line environment.

R2CLi is built on top of the R2 Framework, which supports a wide range of file formats, including executables, firmware, and even custom binary formats. The tool inherits R2’s extensive set of commands for analyzing code, data structures, and control flow graphs, while also offering additional features tailored for CLI users. It allows for scripting and automation, enabling users to chain commands, process large binaries efficiently, and integrate analysis into larger workflows.

One of the key advantages of R2CLi is its flexibility. Users can execute commands interactively or via scripts, making it suitable for both exploratory analysis and automated tasks. The tool also supports remote debugging and can interface with other tools in the R2 ecosystem, such as Radare2’s GUI (Radare2) and its scripting language (R2Lang). This makes it a versatile choice for those who rely on command-line workflows.

R2CLi is open-source and distributed under a permissive license, allowing for customization and community contributions. It is available for Linux, macOS, and Windows, though its primary development focus remains on Unix-like systems. The tool is regularly updated to support new architectures and features, ensuring compatibility with modern binary analysis challenges. For users already familiar with R2, R2CLi provides a natural extension of their workflow, enhancing productivity without requiring a shift to a graphical interface.
