-e maxerrs

The maximum number of tolerable errors. The default number is 50 errors.

4.4DATA FILE FORMATS

Data files must be in one of the following record formats:

•Variable length records

•Fixed length records

For both these types of records an optional field delimiter and an optional record delimiter can be specified. The field delimiter, when specified, should be a single character. By default, comma is the field delimiter. The record delimiter can be specified in the commands file and it can be more than one character. By default, the newline character, \n, is the record delimiter.
