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  partici‐
           pate 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.
