Command to set "date password last changed" of an user? (password aging enabled)

[Markus Braune]

Hi,

I searched the manpage of passwd and the web if there is a command to edit the “date password last changed” of an user in /etc/passwd (HP-UX 11.23, non trusted). When I change the password by "passwd user" I can see the date last changed for example by “passwd –s user”. I am also able to edit this date manually in /etc/passwd (last two characters in pw column).

But is there also a command to edit that "date password last changed"?

I’d like to do that for some training users automated in a script from time to time (like the password was changed 12 weeks ago). If there is no command, what’s the correct way to edit /etc/passwd?

cp /etc/passwd /etc/ptmp
sed ‘s/^user:\([^,]*\),[^:]*:/user:\1,o.zT:/" /etc/passwd > /etc/ptmp
mv /etc/ptmp /etc/passwd

Is that the correct procedure?
I think the advantage of a command would be the automated check & lock of the passwd file.

Thanks for all your hints.

Shalom,

Take a backup of /etc/passwd before you try this.

passwd -x username

Will set your users up to expire somewhat more safely.

Yes. The command is vipw(1m).
But you are own your own to figure out the password expiration encoding.
I have a program to display them, not to create them.
