LOOK(1)                              BSD                               LOOK(1)



NAME
     look - find lines in a sorted list

SYNOPSIS
     look [ -df ] string [ file ]

DESCRIPTION
     The look command 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).  If you don't
     specify a file, look assumes /usr/dict/words with the collating sequence
     -df.

OPTIONS
     -d        Use dictionary order.  Compare only letters, digits, tabs, and
               blanks.

     -f        Fold.  Uppercase letters compare equal to lowercase letters.

FILES
     /usr/dict/words

SEE ALSO
     grep (1), sort (1).
