Как получить cue из разбитого по трекам альбома?

shncue *.flac

#!/bin/zsh

function get_file_metadata(){
	print "Aquiring metadata for $1"
	PERFORMER=$(metaflac --show-tag=ARTIST "$1"|cut -d"=" -f2)
	TITLE=$(metaflac --show-tag=TITLE "$1"|cut -d"=" -f2)
	TRACKNUMBER=$(metaflac --show-tag=TRACKNUMBER "$1"|cut -d"=" -f2)
}

function get_album_metadata(){
	print "Aquiring album metadata"
	ALBUM=$(metaflac --show-tag=ALBUM "$1"|cut -d"=" -f2)
	DATE=$(metaflac --show-tag=DATE "$1"|cut -d"=" -f2)
	GENRE=$(metaflac --show-tag=GENRE "$1"|cut -d"=" -f2)
	PERFORMER=$(metaflac --show-tag=ARTIST "$1"|cut -d"=" -f2)
}

get_album_metadata 01.*.flac

print "Writing CUE header..."
echo "REM GENRE \"$GENRE\"" > cue
echo "REM DATE $DATE" >> cue
echo "PERFORMER \"$PERFORMER\"" >> cue
echo "TITLE \"$ALBUM\"" >> cue
echo "FILE \"$DATE. $ALBUM.flac\" WAVE" >> cue

print "Writing track entries..."
foreach flac (*.flac) get_file_metadata "$flac";
	INDEX=$(shncue *.flac|grep -A1 "TRACK $TRACKNUMBER"|tail -1)
	echo "  TRACK $TRACKNUMBER AUDIO" >> cue
	echo "    TITLE \"$TITLE\"" >> cue
	echo "    PERFORMER \"$PERFORMER\"" >> cue
	echo "$INDEX" >>cue
end

print "Joining tracks..."
OUTFILE="$DATE. $ALBUM"
shnjoin -o flac -a "$OUTFILE" -q *.flac 

print "Embedding CUE..."
metaflac --set-tag-from-file="CUESHEET=cue" --import-cuesheet-from="cue"\
	"$OUTFILE.flac"
