The steps I would use:

1.  Open the file you want to read with FasterCSV::open()
2.  Open a different file to write into with FasterCSV::open()
3.  Use each() to read the rows from the in file
4.  Inside the each() block, write the rows to the out file
5.  Add some code before the write that changes the line you want to  
change (if you really want an exact row, FasterCSV#lineno() can help)
6.  Rename new file to replace old (if you don't want to save the old  
data)

If you get stuck along the way, send us your code and we will try to  
help.
