questions on burning cd with mkisofs and cdrecord

Hello,

I try to build a script and I haven't found answers to few questions.
Perhaps, some scripts already exist on the net but I didn't find some.
May be somebody can suggest some ?

However, I would like to be able to choose between data, audio, and mixed CDs. From now on, I use mkisofs to give a label to cds I build.
It is possible to burn a cd without the mkisofs step, and I have read it was more safe to build an iso image before burning a cd.

1) Is it possible to label a cd while burning without mkisofs ?
2) It is possible to use multi-session on an audio-cd, but can one overburn an audio-cd ?
3) Can the cd-player compute the exact size of a CD-ROM before burning it ?
A complement is: can the cd-player know (before burning) cd-rw or a single cd-rom ?

Thanks, Xround.

I don't have all of your answers but here is a script which I found. It uses mpg123 to put the mp3 directly onto the cdrom. The key is using -nofix - which basically makes it act like multisession ( keeps the cdrom open for more input ) . I haven't tried to fill up a cdrom yet so I don't know what it will do when the cd is full.

Code:

#!/bin/bash
#decode directly to cdrom
cd /home/images
for i in *.mp3
do
mpg123 --cdr - "$i" | cdrecord -audio -pad -nofix -
done
cdrecord -fix -eject

I have also used the pipe command to send mkisofs directly to cdrecord instead of first creating an iso image. For example:

Code:

cd /mnt/aclinux
mkisofs -R -J . | cdrecord -v dev=ATA:1,0,0 -eject -multi -data -
