I want a NON-INTERACTIVE command to set root password.

Similar to how I can set a samba password by supplying an encrypted
password on command line, or a password for the user in a self install
CD.

I am not interested in BS lectures about security.

This is for a large number of GUI-less production machines that we'll
be setting up, not for grandma's web browser box. The machines are all
fully configured with a big install script, except that I need to set
root password manually, which I do not like to do.

So. Is there some way to set

set-encrypted-password root <encrypted password>

thanks

man passwd:

--stdin
This option is used to indicate that passwd should read
the new password from standard input, which can be a
pipe.

I think that your passwd is different from my passwd, mine does not
have this option. And I would prefer to deal with an excrypted
password.

Uhm...reread the two phrases above. Anyway, why not edit /etc/shadow
directly then?

awk -F':' -v OFS=':' '/^root/{$2=encryptedpassw}1' /etc/shadow > newshadow

With sed you can even do in-place editing (carefully):

sed -i 's/^root:[^:]*/root:encryptedpassword/' /etc/shadow
