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 (\(oq-\(cq).
-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.
