Linux Assembly Tutorial Step-by-Step Guide

Mainly, the reason for this tutorial is to make assembly programming easier, better and more practical by doing it in Linux instead of DOS. Also, it may teach you a bit of Linux while you're at it (unless you're already at home with it).

This tutorial is an introduction to coding assembly in Linux. There are two "versions" to accommodate various people:

The Step-by-Step Guide: This version explains everything in detail. It assumes that you have done at least a little bit of DOS assembly, and that you have Linux on your computer (although you may not have used it much yet). Since not everyone may know how to use Linux, there are links to sections where I explain how to do basic things like use the terminal and the DOS-equivalent commands.
The Quickstart: If you're in a hurry and just want to see a Linux assembly program, compile it and run it, this is for you. It assumes that you understand basic DOS assembly, and that you know how to use the terminal. Basically, it just points out the differences between a Linux and DOS assembly program with just enough explanation not to confuse you.

The assembler I'll be using is NASM (Netwide Assembler). Lots of the stuff in this tutorial came from other tuts and the NASM documentation – see the References section for more info.
