update−passwd − safely update /etc/passwd, /etc/shadow and /etc/group
update−passwd [options]
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 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
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.
