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 (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 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.
