Did I corrupt my init file?

I was looking thru it and saw that it was starting up in init5, when I wanted it to start up in init3.

So I changed it to 5 to 3 and now it starts up in the GUI, and I don't want that. I guess I was thinking about Redhat and 3 is text based and 5 is GUI.

When I vi the file, the output is all screwed up.

Can I just install it from the Knoppix 3.3 cdrom or can someone post theres?

thanks
