Mac OS X Unix Tutorial

by Adrian Mayo - Senior Editor for Mac OS X Unix, Janice Mayo - Senior Editor for Mac OS X Unix

Are you an old hand at the Mac? Do you love Aqua? Does the Unix beast lurking beneath the surface scare you? Yes? Then perhaps I can help you tame the beast, and put it to good use.

This tutorial is presented as a regular column and takes the Unix beginner through the basics of using the Terminal application - the means by which one speaks and listens Unix. If you need to use Unix, or are merely interested in what it is all about, then read on. I hope to help you harness some of the power at your finger-tips - that's your keyboard fingers, not your mouse fingers!

The Unix Tutorial will appear in instalments.

Advanced Mac OS X Unix

by Adrian Mayo - Senior Contributing Editor

This section of the Learning Centre expands on topics introduced in the Unix Tutorials. Some aspects of Unix warrant a more in depth discussion useful to the advanced user, but not necessary for day-to-day usage. Each is self-contained focussing on a specific topic, and is presented specifically from a Mac OS X perspective.

Some Unix knowledge is assumed, which can be gained from reading the Unix Tutorials.
