DD command with label of dvd

Hello Everybody

I want a script that copy a dvd to an iso file.
This is what I got.

Code:

eject -t /dev/sr0 &&

sleep 30 &&

blkid -s LABEL -o value /dev/sr0 &&

# copy dvd to a location on my pc
dd if=/dev/sr0 of=/home/gebruiker/Bureaublad/LABEL.iso &&

rename 's/oldname/newname' *.iso $LABEL.iso &&

# eject drive
eject /dev/sr0

The problem is that I can't get automatically the label of the dvd in the name of the iso file.

How can I fix this?

Kind regards
Ruben

Things don't happen by magic, you need to create the variable. Something like this might work.

There are some interspaces in the dvd name.
That's a problem for the script

So get rid of them - simplest would be to pipe the blkid output into tr; underscore is a viable alternative to a blank. Then your $LABEL is correct without further processing. You can avoid the word splitting with quotes, but there is always a "corner case" where it gets ugly.
