BI 4.1 file system clean up

HI All,

we would like to clean up os level file system using a script. we have the script ready but cannot schedule a cron job in linux. is it possible to schedule the script from BI 4.1 scheduler? to be more procise we would like to clear lcm biar files under following directory every 10 days /usr/sap/SID/sap_bobj/tomcat/temp .

thanks,

Ranjith
