       unshadow - combines passwd and shadow files


       unshadow password-file shadow-file


       This  manual  page  documents  briefly  the  unshadow  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 unshadow tool combines the passwd and shadow files so John can  use  them.  You  might
       need  this since if you only used your shadow file, the GECOS information wouldn't be used
       by the "single crack" mode, and also you wouldn't be able to use the '-shells' option.  On
       a normal system you'll need to run unshadow as root to be able to read the shadow file.

       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.
