update-passwd - safely update /etc/passwd, /etc/shadow and /etc/group
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).
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 dont do anything. -v, --verbose Give detailed information about what we are doing. A second -v gives additional detail. -n, --dry-run Dont do anything but only show what we would do. -L, --no-locking Dont 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
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.
