UPDATE-PASSWD(8)            System Manager's Manual           UPDATE-PASSWD(8)



NAME
       update-passwd - safely update /etc/passwd, /etc/shadow and /etc/group

SYNOPSIS
       update-passwd [options]

DESCRIPTION
       update-passwd   handles   updates   of   /etc/passwd,  /etc/shadow  and
       /etc/group on running Debian systems.  It compares the current files to
       master  copies, distributed in the base-passwd package, and updates all
       entries in the global system range (that is, 0-99).

OPTIONS
       update-passwd follows the usual GNU  command  line  syntax,  with  long
       options starting with two dashes ('-').

       -p, --passwd-master=FILE
              Use FILE as the master copy of the passwd database.  The default
              value is /usr/share/base-passwd/passwd.master.

       -g, --group-master=FILE
              Use FILE as the master copy of the group database.  The  default
              value is /usr/share/base-passwd/group.master.

       -P, --passwd=FILE
              Use  FILE  as  the system passwd database.  The default value is
              /etc/passwd.

       -S, --shadow=FILE
              Use FILE as the system shadow database.  The  default  value  is
              /etc/shadow.

       -G, --group=FILE
              Use  FILE  as  the  system group database.  The default value is
              /etc/group.

       -s, --sanity-check
              Only perform sanity-checks but don't do anything.

       -v, --verbose
              Give detailed information about we are doing.  A second -v gives
              additional detail.

       -n, --dry-run
              Don't do anything but only show what we would do.

       -L, --no-locking
              Don't attempt to lock the account database.  This should only be
              used for debugging purposes.  I repeat: do not  do  this  unless
              you are really sure you need this!

       -h, --help
              Show a summary of how to use update-passwd.

       -V, --version
              Show the version number

BUGS
       At  this  moment  update-passwd  does  not  verify the shadow-file.  It
       should check if the entries in the passwd are also in shadow  and  vice
       versa, and that passwords are not present in both files.
