UNIX_UPDATE(8)            (06/08/2020)             UNIX_UPDATE(8)

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

     SYNOPSIS
          unix_update [...]

     DESCRIPTION
          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.
