Hi,

Something like this should work. This probably isn't the best written shell script you're ever gonna see but I just knocked it out and it works for me Smilie

Read the comments in the code to see what each part is doing.

Code:
#! /bin/bash
#
# script to automate password reset
#
# declare variables
declare USERNAME="TEST" # This allows the username to be changed or multiple usernames specified by creating a new variable
declare TMP_VAR="" # Temporary variable we will use to store value of user check
#
echo "Start password reset script"
# first check to make sure user exists
TMP_VAR=`grep ^$USERNAME: /etc/passwd` > /dev/null > 2>&1
if [ "$TMP_VAR" = "" ];
then {
	echo "User $USERNAME does not exist"
	# exit cleanly with result code 1 (not successful)
	exit 1;
}
else {
# if username exists proceed to reset password
passwd --stdin $USERNAME < pass_file # pass_file is the file where the password is stored you want to use
}
fi
# exit cleanly and return 0 result code
exit 0;

Since you say you want to "automate" this change I'm thinking it's going to be done on a regular basis so my opinion is to add it to the crontab for root, or someone who has privileges to change user passwords. I don't know how much you know about crontabs and their purpose and so on but you can just search the forum/google and you should see plenty of examples. If you wanted to schedule the job to run at midnight on the first of every month your entry into the crontab might look like this:

Code:
0     0     1     *     *     /full/path/of/script/password_change.sh

NAME
lppasswd - add, change, or delete digest passwords. SYNOPSIS
lppasswd [ username ] lppasswd -a [ -g groupname ] username lppasswd -x username DESCRIPTION
lppasswd adds, changes, or deletes passwords in the CUPS digest password file, passwd.md5. When run by a normal user, lppasswd will prompt for the old and new passwords. When run by the super-user, lppasswd can add new accounts (-a username), change existing accounts (user- name), or delete accounts (-x username) in the digest password file. Digest usernames do not have to match local UNIX usernames. OPTIONS
lppasswd supports the following options: -g groupname Specifies a group other than the default system group. SECURITY ISSUES
By default, the lppasswd program is not installed to allow ordinary users to change their passwords. To enable this, the lppasswd command must be made setuid to root with the command: chmod u+s lppasswd While every attempt has been made to make lppasswd secure against exploits that could grant super-user privileges to unprivileged users, paranoid system administrators may wish to use Basic authentication with accounts managed by PAM instead.
