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, 099).
OPTIONS
update-passwd
follows the usual GNU command line syntax, with long
options starting with two dashes (-).
R -p , --passwd-master=FILE
Use FILE as the master copy of the passwd database.
The default value is
R /usr/share/base-passwd/passwd.master .
R -g , --group-master=FILE
Use FILE as the master copy of the group database.
The default value is
R /usr/share/base-passwd/group.master .
R -P , --passwd=FILE
Use FILE as the system passwd database.
The default value is
R /etc/passwd .
R -S , --shadow=FILE
Use FILE as the system shadow database.
The default value is
R /etc/shadow .
R -G , --group=FILE
Use FILE as the system group database.
The default value is
R /etc/group .
R -s , --sanity-check
Only perform sanity-checks but don't do anything.
R -v , --verbose
Give detailed information about we are doing.
A second -v gives additional detail.
R -n , --dry-run
Don't do anything but only show what we would do.
R -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!
R -h , --help
Show a summary of how to use
R update-passwd .
R -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.
