Records:

500|NY|111-111-1112|A^M
^Z
1000|NY|111-111-1111|F^M
^Z

When I use nzload to load into the database, the 2 records are loaded fine.  But the other 2 with ^Z are written to log file stating
number of bad records:      2.  I'm trying to error code this in my unix script.

grep "number of bad records:       0" test.log
errorcode=$?

If errorcode=0 , then contiue to another step, else email bad records found. 
How can I code in the nzload command, so it'll totally ignore any records with ^Z.
