I recently explored burning discs from the command line. To make things even more convenient, I can employ emacs dired to help in selecting the files. That is, suppose I have some files in a directory opened in dired. I can mark the files I want to be burnt, and invoke ! (dired-do-shell-command) on those files with the command:
<pre class="src src-sh">growisofs -dvd-compat -input-charset=ISO-8859-1 -full-iso9660-filenames -Z /dev/sr0 -R -J -pad * && eject /dev/sr0
I can also invoke & (dired-do-async-shell-command) with the above command without the && eject /dev/sr0 (the * arguments will also be passed to this) to continue using the current emacs instance and view the progress in stdout.
