Recording a directory on a DVD through the command line

[Paul Smith <phhs80@xxxxxxxxx>]

Dear All

I would like to record an entire directory and all its subdirectories
(recursively) on a DVD by using the command line. Could someone here
please help me? That is true that I could do that, easily, with k3b,
but I would like to learn how to do that with the command line.

Thanks in advance,

Paul
