duplicate in text file

I have my SQL server reads a text file into a temp table, then it copies
that data over to a main table, but it looks to see if a particular filed
has a certain value, if it does, it updates that record instead of creating
a duplicate.
But, what I am finding is that if the text file has duplicate records in it,
it will duplicate into the main table.
Any ideas on how I can weed out duplicates from the text file that I am
importing?You can add an intermediate process to remove the duplicates after they are
loaded into the temp table and before perorming the insert or the update to
the main table.

DISTINCT at the temp table? prior to entering into the main table
