       unique - removes duplicates from a wordlist


       unique output-file


       This  manual page documents briefly the unique command, which is part of the john package.
       This manual page was written for the Debian GNU/Linux distribution  because  the  original
       program  does not have a manual page.  john, better known as John the Ripper, is a tool to
       find weak passwords of users in a server.
       The unique tool finds and removes duplicate entries from a  wordlist  (read  from  stdin),
       without  changing  the  order.  This is important to increase the performance of john when
       using the wordlist method.


       john(8), mailer(8), unafs(8), unshadow(8).

       The programs are documented fully by John's documentation, which should  be  available  in
       /usr/share/doc/john or other location, depending on your system.
