positional arguments:
  FILE                  The CSV file to operate on. If omitted, will accept
                        input on STDIN.

                        A comma separated list of column indices or names to
                        be extracted. Defaults to all columns.
  -l, --linenumbers     Insert a column of line numbers at the front of the
                        output. Useful when piping to grep or as a simple
