Hi,

is there a software/script out there that can help me figure out the total image
size to be put on dvd without actually creating the image?

I have hundreds and thousands of files in 8+ nested directories that I need to burn
on dvd. i have to someway calculate the filesize, filename length, directory length,
etc.etc.etc., chop them into like dvd1, dvd2, dvd3 dirs, and have my automated
script burn those dvd dirs....

can anyone help? ...thanx...

Part of the solution is to play around with the du command. See man du. For example you could find the size of a directory called /home/user/biggy with:

MYCWD=${PWD}
cd /home/user/biggy
THISSIZE=$(du -s -h)
cd ${MYCWD}

mkisofs -print-size [..parameters needed to make the image]
see man mkisofs for details.
