Automatic purge of slave binlogs replication

In the crontab I put the following:

30 2 * * 0,2,4,6 /usr/local/axisutilities/removelogs.sh

My script is like this:

#!/bin/bash
/usr/local/mysql/bin/mysql -paxismobile < /usr/local/axisutilities/deletelogs.sql
Which calls the following file.

Deletelogs.sql:

PURGE MASTER LOGS BEFORE now() -interval 24 hour;
PURGE BINARY LOGS BEFORE now() -interval 24 hour;
exit
