    NAME
         look - find lines in a sorted list

    SYNOPSIS
         look [ -df ] string [ file ]

    DESCRIPTION
         Look consults a sorted file and prints all lines that begin
         with string.  It uses binary search.

         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.

    FILES
         /usr/dict/words
