I don't think it's done because I can't use the up or north key to scroll<br>

It is done because you got a prompt ($) back. The<br>
reason you can scroll is that when you su'd to<br>
the mythtv user, your shell became sh. You're<br>
accustom to using the bash shell.<br>
<br>
Had you typed:<br>
<br>
sudo su --preserve-environment mythtv<br>
<br>
you would have used the same environment.<br>
See: man su for details.<br>
<br>
If you don't believe that it's done, why not<br>
use the ls command and see if the file was<br>
created. Also, you could type man touch to<br>
see exactly what the command does.<br>
<br>
You'd also learn that you can touch more than<br>
one file at a time. In fact, you could do all<br>
of them on one command line.<span class="HOEnZb"><font color="#888888"><br>
