Top Forums Shell Programming and Scripting Is there a way to automatically prepopulate a password field? Post 302082129 by nathan on Monday 31st of July 2006 12:15:29 PM

This is from my manual page on 'passwd'. Yours may not have this option. I believe some versions of passwd are intentionally written so that the password must be entered from the keyboard.

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

pwconv(1M)                                                System Administration Commands                                                pwconv(1M)

NAME
pwconv - installs and updates /etc/shadow with information from /etc/passwd SYNOPSIS
pwconv DESCRIPTION
The pwconv command creates and updates /etc/shadow with information from /etc/passwd. pwconv relies on a special value of 'x' in the password field of /etc/passwd. This value of 'x' indicates that the password for the user is already in /etc/shadow and should not be modified. If the /etc/shadow file does not exist, this command will create /etc/shadow with information from /etc/passwd. The command populates /etc/shadow with the user's login name, password, and password aging information. If password aging information does not exist in /etc/passwd for a given user, none will be added to /etc/shadow. However, the last changed information will always be updated. If the /etc/shadow file does exist, the following tasks will be performed: Entries that are in the /etc/passwd file and not in the /etc/shadow file will be added to the /etc/shadow file. Entries that are in the /etc/shadow file and not in the /etc/passwd file will be removed from /etc/shadow. Password attributes (for example, password and aging information) that exist in an /etc/passwd entry will be moved to the corre- sponding entry in /etc/shadow. The pwconv command can only be used by the super-user. FILES
