Hi Chris, Orin, and Others,
 
You pointed to a number of on-line Unix tutorials for information on
basic concepts and applications (such as terminal) that are used on
the Mac, and also noted the problems of distinguishing details that
arise from the different flavors of unix and linux.

A good, but slightly old source of information on the differences between
Mac OS X and Unix is "Top Ten Mac OS X Tips for Unix Geeks" at the
O'Reilly macdevcenter pages:

http://www.macdevcenter.com/pub/a/mac/2002/10/22/macforunix.html

This is an old document that outlines the different file layout of Mac OS X,
what shell is used, what happens at startup and shutdown, etc.  It was
written before Tiger, but was updated last summer because the page 
continued to be popular.  The audience is users who are coming to the Mac
with some familiarity of unix or linux, but who want a quick rundown of
what's different in Mac OS X. While this doesn't cover more recent items
(such as the use of Macports to build open source software in addition to
Fink, which is mentioned), this is  useful page.

A couple of extra accessibility pluses for the O'Reilly macdevcenter.com
pages:  
1. You can use the item chooser menu to select the "print" link and get a
printer-friendly version of this page at:  
http://www.macdevcenter.com/lpt/a/2792
2. The original web page also has a "Listen" link that lets you listen to the
content of this page or navigate to download an mp3 file of this page from
the player that get launched.  (This page pre-dates VoiceOver).  You proably
won't want to listen to the mp3 file unless you can download it and speed it
up, and they haven't updated the recorded version -- only the web page
versions.  So, for example, you'd hear that the default shell is tcsh (instead
of bash), and other items that have changed.

The O'Reilly Press books are also availabie internationally to visually disbled
