**-s**\ [*cols*\ ][\ **a**\ \|\ **r**]
    Suppress output for records whose *z*-value equals NaN [Default
    outputs all records]. Append **a** to skip records where at least
    one field equal NaN. Append **r** to reverse the suppression, i.e.,
    only output the records whose *z*-value equals NaN. Alternatively,
    indicate a comma-separated list of all columns or column ranges to
    consider for this NaN test.
