Teradata tpt

Hi All, I am new to this post and in teradata.

I am trying to create one unix script that will do the table sync from one to another for COB sync with tpt utility.

I need script to unload from source table and load to target table by tpt and if possible unload file in delimited.But also I need to generate the dml of the unload file and save it for future use.

Can you please help if there are anything in tpt like .ml script in fast export automatically created, else how to achieve that.

Also I want the tpt load should be upsert which tdload is not doing.I tried with tdload but it is only doing insert.
