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 what 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.
