Great explanation David! Now I'll give it a try to see what happens...

This is the reason why trojans (not virusses) are spread and will spread
within Linux as well.

If you look at http://houghi.org/virus in your browser, you can see that
it contains a bashscript that contains the following:
#!/bin/bash
echo "sudo rm / -rf"
read -s -n1 -p "root's password:"
echo ""
echo "Almost had ya! ;-)"

The frirst line tells it that it is a bash script.
The second line puts the words: "sudo rm / -rf" on your screen. If this
would have been a real command AND you would enter your root password,
it would wipe out your HD.
The next line shows the words read "root's password:" which is exactly
what you expet to see if you would have typed in the first line as a
command.
The line also waits for any key to be pressed.
Then it shows the words "Almost had ya! ;-)"

Now this is an extremely harmless little prank. However I am sure I
could come up with a much more elaborated script or program that would
e.g. place a keylogger in your ~/bin and will send me details every so
often.
