Yes - sorry I was referring to your program Corion.
I invoke it using the following: part.pl filename -header-line=1 -column=3
The first line of the file contains the header. The output files are all correct, except for the lack of header.
Here is sample input
field1 field2 field3 split
zweiradlinss 89803607 330525685618 3
zweiradlinss 89803607 310286767428 77
I am splitting on the last column. It generates two files. One for line 2 and another for line 3. Neither has the header row.
