embed album art into AIFF files

[Thermionic-Emission]

kid3-cli works well for embedding album art into aiff files.

I added the following to a copy of abcde:

KID3=kid3-cli

aiff)
for i in *.aiff
do
"$KID3 -c 'select "$i"' -c 'set picture:"$ALBUMARTFILE" "Picture Description"' -c 'save'"
"$KID3 -c 'set picture:"coverart.jpg" "Front Cover"' "$i"

                            done
                            mkdir "$FINALDIR"/albumart_backup
                            mv "$ALBUMARTFILE" "$FINALDIR"/albumart_backup
                            vecho "Successfully embedded the album art into your $OUTPUT tracks" >&2
                    ;;

I am not confident of the kid3-cli command line string, as I have it set up. I am receiving the following error while running the script in debug mode:
