I am trying to extract only the headers from the csv file using Nifi. I am new to Nifi and I am not much used to the processors. I am trying to use GetFile->ExtractText->PutFile to get the header line and just output that into a different directory. And this is my regex used inside the ExtractText: ^(.*)n
