Hot to BURN FILES to a DVD DISK from Shell/Console
I was looking the way to burn some files into DVDs and I ‘course RFM ( Read the Fkn Manuals ) and this are the results:
—> Step ONE ( Start burning a multisession DVD )
# growisofs -Z /dev/dvd -R -J file* dir/
–> Step TWO if you need to burn more that once don’t worry you can do that xD
# growisofs -M /dev/dvd -R -J anotherfile andanotherfile...
–> Finally CLOSE THE SESSION:
# growisofs -M /dev/dvd=/dev/zero
EASY 
NOTES: I assume my DVD-WR are /dev/dvd you must be sure about yurs
