slowly...it's the first time for me, that i'm using a linux-based system

It's impossible for me to move any file because of the message "that's a NTFS-Partition and it's to dangerous to write something on it".

1.Where's the "command line"?
2.What do you mean with "Say cdrecord --scanbus " ? -> make this command in the command line and i get the information about my cdburner?
3.Use "#" in the commands or not?

Sorry for the dumb question but it's realy the first time...thanks.
