How to start automatically a script after that the knoppix user is logged on.

For openers, /etc/rc.local is directory.
Define your shell scripts appropriately and save them there.
They get executed in the order presented in the directory.

You have here a melange of things (in post #5)
that would surprise me if it did anything useful as it stands.
Perhaps 'try it and find out' is a bit premature.

In regards to I/O re-direction, of any sort, I can't help you.

I think you will get more help from some quarter if you
define in words, more than a short sentence just what you hope to achieve.

post #7 got past me with the darn ten minute edit rule

wrong

/etc/rc.local is an executable script itself.
your can reference other scripts in it.

Best to keep things small and separate.

Remainder of my post #7 about right, I think.

I copied script.sh inside /etc/

#!/bin/sh

clear
read -p "Insert your Windows installation disk and press a key to continue" disco
sudo mount -t auto /dev/cdrom /mnt/cdrom

I call it inside the /etc/rc.local file :

rc.local

....
/etc/script.sh

I made it executable,with chmod +x script.sh

and at the end I re-booted Knoppix with runlevel 2,but when it has finished to be loaded in memory,the script.sh is not started.

Since you made it executable it is better to remove the .sh extension and place your script in /usr/sbin, then make a line in /etc/rc.local
Make sure again it is chmod 755

rc.local is the last script executed at every runlevel 2,3,4 and 5
