One of the great benefits of Unix is the vast array of free and inexpensive software tools that are available for the platform. Programming with GNU Software provides an overview of how C and C++ programmers can use some of these tools: the source-code editor Emacs, the gcc compiler, gdb debugger, gprof profiler, and the RCS version-control system. The book offers a quick-paced tutorial that, unlike some introductions to Unix tools, is particularly focused on the needs of C programmers.
