       unix_update - Helper binary that updates the password of a given
       user

SYNOPSIS         top

       unix_update [...]

DESCRIPTION         top

       unix_update is a helper program for the pam_unix module that
       updates the password of a given user. It is not intended to be
       run directly from the command line and logs a security violation
       if done so.

       The purpose of the helper is to enable tighter confinement of
       login and password changing services. The helper is thus called
       only when SELinux is enabled on the system.

       The interface of the helper - command line options, and
       input/output data format are internal to the pam_unix module and
       it should not be called directly from applications.
