TLDR: GDB (GNU Debugger) is an open-source debugging tool introduced in 1986 as part of the GNU Project. It provides developers with powerful capabilities to analyze and control the execution of programs written in C, CPP, and other supported languages. By enabling features like breakpoints, watchpoints, and step-through execution, GDB helps identify runtime errors, trace function calls, and inspect program states to resolve software bugs efficiently.

GDB operates by interacting directly with the compiled executable and, optionally, with the source code. It supports advanced functionalities such as attaching to running processes, analyzing core dumps, and modifying variables at runtime. GDB's command-line interface provides fine-grained control for developers, while GUI-based frontends like Eclipse CDT or DDD (Data Display Debugger) make the tool more accessible by visualizing debugging data. It also integrates seamlessly with IDEs for enhanced debugging workflows.

A key feature of GDB is its support for remote debugging, which allows developers to debug applications running on different hardware or environments, such as embedded systems. This flexibility, coupled with its extensibility through scripting languages like Python, has made GDB a cornerstone of debugging for decades. Regular updates and a strong community ensure that GDB continues to adapt to the needs of modern software development.
