hi everbody,
i want to burn a dvd with some data directly without creating .iso file before burning.right now i use to create an iso file first using mkisofs or dd command and then burn using cdrecord command.But i want to know whether is it possible to directly burn dvd without creating iso first?i use following commands-

and then burn iso using cdrecord

please merge above two steps into one

The tool you are looking for is growisofs. Does exactly what you want.

let me explain what i really want to do.i have two dvd-rw attached on my pc and i want to burn dvd to dvd with both dvd-rw filled.means dvd to dvd burning without saving iso image

Sorry, seems to me that I misunderstood your question. I thought that you want to burn some folders from your harddisk to a CD/DVD without making an ISO-image first, that is what growisofs is for. I don't think that you can use it for a direct copy, I think the simplest way would be to use a graphical tool for that, but may be anyone else can help here.

I think you can do it this way, and this is the way I'd prefer. Make a named pipe. This is a special file which you can pipe data to, then read from. It doesn't actually write to disk.

mkfifo image.iso

This makes a pipe

Then read the dvd outputting to this file.

readcd dev=/dev/dvd f=image.iso

Replace /dev/dvd to the device containing the source DVD. you may need to run 'readom' instead of 'readcd'.

Then, while thats running, in another terminal, run

growisofs -Z /dev/dvdwriter=image.iso

agan, replace /dev/dvdwriter as necessary. Despite the fact the data 'appears' to be written and read from a disk, its actually piped from one program to the other, so its all done on the fly.


There might be a way to pipe the output of one program to the other. You can pipe the output of readcd to stdout like this

readcd dev=/dev/dvd f=-

and growisofs can burn from stdin like this
growisofs -Z /dev/dvdwriter=/dev/stdin so maybe this will work

readcd dev=/dev/dvd f=- | growisofs -Z /dev/dvdwriter=/dev/stdin

Wouldn't this work:

/dev/dvd is the source
/dev/dvdrw is the destination

I've never tried this, so I don't know if it'll work.

how about dd if= old-dvd-cd of= new dvd-cd
