====== 2. Introduction ======

This is for people who are new to unix, especially people who are new to unix & new to Super Dimension Fortress (SDF), a public access unix system.

I sometimes hang out in the chat rooms on SDF, & almost every day someone enters who has recently created an account & asks how to get started using unix & the features of SDF. It's an awkward situation because there is a lot to know to get started with unix; it would be difficult to explain it all in a chat room. What's more, most of the regulars in those chat rooms have seen & answered the question enough times that they understandably do not look forward to doing so again.

So I'm answering that question here, once. If all goes well, when someone enters a chat room & asks how to start learning about unix, someone can point them to this article.

===== 2.1 What to read first =====

If you already know what unix is, or if you don't but you also don't enjoy reading about petty controversies about a definition, skip the <nowiki>''</nowiki>What is Unix<nowiki>''</nowiki> chapter & start reading Chapter 4 <nowiki>''</nowiki>Some Basic Commands<nowiki>''</nowiki>.
