Copy your CDs/DVDs collection easily on your Mac

After collecting for years music and ripping it to mp3, back then when HDD or SSD were expensive I used to save those to CDs and later on on DVDs. I used some nice software to catalogue the mediums so I know where what track or album is.
Some days ago I decided to copy all of the music to a HDD (actually two, that are being mirrored) as not only of convience, but unfortunately some of the CDs started falling apart.
So here is a simple shell-bash script (just save it as i.e. copy.sh) that will help you do so.
You got to the terminal, do a 'diskutil list' to recognize what disk the CD/DVD drive ist and then u start the script with 'caffeinate -i sh copy.sh disk3' (supposed you saved it as copy.sh and the drive is disk3). The good thing is you can work normally on your Mac while it automatically does everything - after ejecting the Medium, you put a new one in and close it! Simple as that, when finished you close the Terminal ,) Enjoy

P.S.: Volumes/MusicArchiv/Alben/$opticalMedia --> This is the location where it is saved, in that case my external Volume called MusicArchiv ind the folder Alben where it creates a folder named like the Name of the Medium.

#/bin/bash
while [ 0 ]
do
opticalMedia=`df | grep $1 | cut -d '/' -f 5`
if [ -d "/Volumes/$opticalMedia" ]; then
    if [ ! "$opticalMedia" ]; then
        printf "."
        sleep 3s
        continue
    fi
    printf "\n"
    echo $opticalMedia
    if [ -d "/Volumes/MusicArchiv/Alben/$opticalMedia" ]; then
        timestamp=`date +"%%Y%m%d_%H%M"`
        targetname="$opticalMedia-$timestamp"
    else
        targetname="$opticalMedia"
    fi
    rsync -aEp --progress "/Volumes/$opticalMedia/" "/Volumes/MusicArchiv/Alben/$targetname"
    diskutil eject /dev/$1
else
    echo "error"
fi
done
