Why doesn't mysql -uroot -p <db> -e "commands" not work when I define a delimiter?

The following command works:

mysql -uroot -p radius -e "DROP PROCEDURE IF EXISTS sp_monthly_table_backup; ";

The same command with delimiter does not work:

mysql -uroot -p radius -e "DELIMITER $$ DROP PROCEDURE IF EXISTS sp_monthly_table_backup; END $$ DELIMITER;";

This is just part of a command block I want to make, complete would be like this:

DELIMITER $$
DROP PROCEDURE IF EXISTS sp_monthly_table_backup $$
CREATE PROCEDURE sp_monthly_table_backup(OUT Msg varchar(100))
sp: BEGIN
DECLARE radacct_pmonth varchar(30);
DECLARE radpostauth_pmonth varchar(30);
DECLARE excessao SMALLINT DEFAULT 0;
DECLARE CONTINUE HANDLER FOR SQLEXCEPTION SET excessao = 1;


START TRANSACTION;
SELECT CONCAT('radacct_',YEAR(NOW()), MONTH(NOW())-1) INTO @radacct_pmonth;
SET @str=CONCAT("CREATE TABLE IF NOT EXISTS radius_table_bkp.",@radacct_pmonth," SELECT * FROM radius.radacct;");
PREPARE stmt FROM @str;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;

IF excessao = 1 THEN
SELECT 'FAILED: Erro ao criar copia da tabela radacct' As Msg;
ROLLBACK;
LEAVE sp;
ELSE
DELETE FROM radius.radacct WHERE acctstoptime < date_sub(NOW(), INTERVAL 1 MONTH);
IF excessao = 1 THEN
SELECT 'FAILED: Erro ao remover registros com mais de um mes de radacct' As Msg;
ROLLBACK;
LEAVE sp;
ELSE
SELECT CONCAT('radpostauth_',YEAR(NOW()), MONTH(NOW())-1) INTO @radpostauth_pmonth;
SET @str2=CONCAT("CREATE TABLE IF NOT EXISTS radius_table_bkp.",@radpostauth_pmonth," SELECT * FROM radius.radpostauth;");
PREPARE stmt2 FROM @str2;
EXECUTE stmt2;
DEALLOCATE PREPARE stmt2;

IF excessao = 1 THEN
SELECT 'FAILED: Erro ao criar copia da tabela radpostauth' As Msg;
ROLLBACK;
LEAVE sp;
ELSE
DELETE FROM radius.radpostauth WHERE authdate < date_sub(NOW(), INTERVAL 1 MONTH);
IF excessao = 1 THEN
SELECT 'FAILED: Erro ao remover registros com mais de um mes de radauthpost' As Msg;
ROLLBACK;
LEAVE sp;
ELSE
SELECT 'SUCCESS: Rotina executada com sucesso' As Msg;
COMMIT;
END IF;
END IF;
END IF;
END IF;
END $$
DELIMITER ;

Only I need to enter these commands in a shell script, so I need to use mysql -u <user> -p <db> -e "<commands>". I'm also using '/' to continue the commands on the bottom lines, like this:

mysql -uroot -p radius -e "DROP PROCEDURE IF EXISTS sp_monthly_table_backup; ";
CREATE PROCEDURE sp_monthly_table_backup(IN databasebkp varchar(30), IN table varchar(30), OUT Msg varchar(100)) \
sp: BEGIN \
DECLARE table VARCHAR(30); \
DECLARE dbbkp varchar(30); \
DECLARE excessao SMALLINT DEFAULT 0; \
(...)
