Thanks for your help in advance .

Depending on the OS you use, all crontabs reside in a directory having the name of the user. On Linux this is for example /var/spool/cron/crontabs or /var/spool/cron/tabs.
You can parse them to see what scripts are triggered. Maybe also check if there is a /etc/cron.deny or /etc/cron.allow to see which crontab is relevant or not.
