Quick bash script to backup mysql databases as separate files similar to how MySQL Workbench does

backup.sh

# Script to backup all mysql tables as separate files

	$CHOWN 0.0 -R $SUBPATH

		$MYSQLDUMP $MYSQL_PERMS $DB $TABLE | $GZIP -9 > $FILE
	done
	echo "$(date +"%d-%m-%Y %H:%M:%S") ...done!"
done

echo "$(date +"%d-%m-%Y %H:%M:%S") All done"

exit 0

I'm doing this

TABLES="$(mysql -h "$HOST" -u "$USERNAME" -p"$PASSWORD" -P "$PORT" -Bse 'SHOW TABLES FROM '$DB)"
for TABLE in $TABLES; do
    $(mysqldump -h "$HOST" -u "$USERNAME" -p"$PASSWORD" -P "$PORT" $DB $TABLE | gzip -9 > "../$STORAGE_FOLDER/$DB/${DB}_${TABLE}_`date +"%Y-%m-%d_%H%M%S"`.sql.gz")
done

but I got error filename is too long. The $TABLE is printing all instead of 1 by 1.
