NAME
     llooookk - display lines beginning with a given string

SYNOPSIS
     llooookk [-ddff] [-tt termchar] string [file]

DESCRIPTION
     The llooookk utility displays any lines in file which contain string as a
     prefix.  As llooookk performs a binary search, the lines in file must be
     sorted.

     If file is not specified, the file /usr/share/dict/words is used, only
     alphanumeric characters are compared and the case of alphabetic charac-
     ters is ignored.

     Options:

     -dd      Dictionary character set and order, i.e. only alphanumeric char-
             acters are compared.

     -ff      Ignore the case of alphabetic characters.

     -tt      Specify a string termination character, i.e. only the characters
             in string up to and including the first occurrence of termchar
             are compared.

     The llooookk utility exits 0 if one or more lines were found and displayed, 1
     if no lines were found, and >1 if an error occurred.

CCOOMMPPAATTIIBBIILLIITTYY
     The original manual page stated that tabs and blank characters partici-
     pated in comparisons when the -dd option was specified.  This was incor-
     rect and the current man page matches the historic implementation.

HISTORY     llooookk appeared in Version 7 AT&T UNIX.
