gdb (GNU Debugger) is a software debugger. It can be used to diagnose software runtime errors, such as segmentation faults, or other errors that are not easily detectable or diagnosable at runtime. It can perform typical debugger functions such as breakpoints, watching, stepping, and so on.

As with most UNIX style programs gdb has a command line interface. ddd is a graphical wrapper for gdb, as well as some other debuggers.
