Beej's Quick Guide to GDB
This is a very quick-and-dirty guide meant to get you started with the GNU Debugger, gdb, from the command line in a terminal. Often times gdb is run via an IDE, but many people out there shun IDEs for a variety of reasons, and this tutorial is for you!
Again, this is only a getting-started guide. There's much much MUCH more to learn about what the debugger does than is written in these few short paragraphs. Check out your "man" pages or the online resources listed below for more info.
This tutorial is meant to be read in order, up to, but not including, the "Misc" section.
