Sqlldr connect, unix batch

Howdy,

Question on sql-loader...

Is there a way for sqlldr to connect to the database from a unix batchscript

without specifying the user/password on the command line, (avoiding the ps security-hole on a unix-server)?

In sqlplus, you can put

   connect user/password
in the beginning of a read-protected sql-script or in login.sql

But how do you handle this with sql-loader?

TIA,
