     The options d and f affect comparisons as in sort(1):

     d	 `Dictionary' order: only letters, digits, tabs and
	 blanks participate in comparisons.

     f	 Fold.	Upper case letters compare equal to lower case.

     If no file is specified, /usr/dict/words is assumed with
     collating sequence -df.
