NAME
unshadow - combines passwd and shadow files
SYNOPSIS
unshadow password-file shadow-file
DESCRIPTION
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.
SEE ALSO
john(8), mailer(8), unafs(8), unique(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.
