ok - I guess I could export the data then use mysql_field_name to get the field values and then somehow write to the first line of the file and push the rest of the data down.
In less there is some way get mysql export to append the data to the bottem of the file instead of writing a new file.
I would think that this isn't that uncommon of a task and there there was a simple line that I could add to the MYSQL command line when I do the export from there.
hmmmm. I'll keep searching.
