OT: crontab arguments question
I need to pass an argument to my program from the crontab entry
Problem: the first argument is taken by an environmental script
Question: how do I provide for this?

Example:
55 13 * * * su - oracle -c /apps/oracle/ppdb_scripts/SidTest/willi.sh ppdb
    the su - oracle -c is required to set certain environmental variable 
or nothing works
    the ppdb is the SID the the su - oracle eats up on the way through, 
and I need to send another ppdb to my program

something like ...
55 13 * * * su - oracle -c /apps/oracle/ppdb_scripts/SidTest/willi.sh 
ppdb ppdb
... except that doesn't work ...

Thank you in advance for any help you may be able to offer
Regards
