Hi NG!
Ubuntu 12.04 LTS
How to check in an index.html if the calling browser's system-os is linux 
or one of the many windows species?

There are JavaScript hacks to do that.  You should check in 
comp.lang.java.javascript and/or comp.lang.javascript.

I'm not sure I understand the question. Is this what you wanted?
   firefox -new-tab gocomics.com
Replace gocomics.com with the URL of your choice. It can take up
to 2 URLs at a time. Any more than that and you get a new window
instead. But you can use multiple commands for that.

Check the user agent header.  Except I don't know how that's done with 
html.

Its not actually.  Its done with JavaScript (which can be embeded in the HTML 
with the <script> tag).  The OP should check in the JavaScript newsgroups or 
on the various and many forums relating to JavaScript and AJAX and Web 
Programming in general.

The OP didn't ask about that. The client side javascript can make all of the
'decisions' needed and then perform whatever AJAX calls needed (if any),
depending one what the OP wants to do. There are any number of things one can
do completely with javascript, such as encode a button or form URL or
something stupid like setting the background color based on what OS the
browser is running, all without specificly phoning home. IF the OP wants to
let the server know, that can be done with an AJAX call. (Actually, the
*server* should already know, simply by looking at the User-Agent header the
browser is sending, assuming that the user has not installed a plugin to alter
the User-Agent header that is sent.)

Assuming he's not just running passive web pages (index.html) that can't 
make decisions based on user agents.

Actually, it can.  Consider index.html containing:

<html><head><script type="text/javascript">function foo() {...}</script></head>
<body onload="foo();">...</body></html>

Javascript is not a 'passive web page' point 1.

The OP never said 'passive web page', just 'index.html'.

Try thinking why a person would need to know what operating system they 
were running lo0cally, and conversely why a server would, remotely.

Would you please tell why? IMHO, a more useful piece of information
is the browser type and version.

Try this:

// This script sets OSName variable as follows:
// "Windows"    for all versions of Windows
// "MacOS"      for all versions of Macintosh OS
// "Linux"      for all versions of Linux
// "UNIX"       for all other UNIX flavors
// "Unknown OS" indicates failure to detect the OS

var OSName="Unknown OS";
if (navigator.appVersion.indexOf("Win")!=-1) OSName="Windows";
if (navigator.appVersion.indexOf("Mac")!=-1) OSName="MacOS";
if (navigator.appVersion.indexOf("X11")!=-1) OSName="UNIX";
if (navigator.appVersion.indexOf("Linux")!=-1) OSName="Linux";

document.write('Your OS: '+OSName);

	Back in ancient days like 15 years ago web-browsing on the Amiga
with AWeb the OS and the browser could not be detected by the sites
or even by the testing sites.  That was fine with me.  But even then
the AWeb browser could spoof Windows if I cared to configure a setting
that way.  Those days I was thrilled to inherit a 28.8 kb modem and 
thought the millennium had arrived when I got a 56 kb modem.

And that's a Good Thing.  I've had enough of web sites that say,
"You're not running Windows.  Back of the bus, boy!"

Well, check my homepage 'dj1wm.darc.de'.
With Win(7) and IE a mdidifile will be played. That is what I intend.
But using linux and firefox as me (newbie) only a popup shows and asks to 
install VLC-player. So what?
