      NAME
           look - find lines in a sorted list

      SYNTAX
           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
