Hi,

I do this using two quickly hacked together scripts as follows - please bear in mind that these scripts are running on Solaris 11 and things are done this way to avoid a problem. But the scripts should be easily adaptable.

Script 1

Code:
for USER in `cat $DATADIR/name_list.txt | awk -F: '{ print $1 }'`
        do
if [ ! -d /export/home/${USER} ]
        then
                echo "The home directory for ${USER} does not exist - create."
                mkdir -p /export/home/${USER}
                if [[ $? -eq "0" ]]
                then
                        useradd -c"XXX Support User" -d/export/home/${USER} ${USER}
                        if [[ $? -eq "0" ]]
                        then
                                echo "Account for user ${USER} Created."
                        else
                                echo "Accounr for user ${USER} could not be created."
                        fi
                else
                        echo "The Account for ${USER} either already exists or could not be setup."
                fi

                echo "Setting the ownership for /export/home/${USER}"
                chown ${USER}:staff /export/home/${USER}
                if [[ $? -eq "0" ]]
                then
                        echo "The ownership of /export/home/${USER} wasx successfully set."
                else
                        echo "There was a problem setting the ownership on /export/home/${USER}"
                fi
                echo "Setting the password for ${USER}"
                echo ${USER} >> $DATADIR/added_users.txt
                ${BINDIR}/set_pw.sh ${USER} Ch4ng3me
        else
                echo "The user ${USER} already exists."
fi
done

Script 2

Code:
#!/usr/bin/expect

set username [lindex $argv 0];
set newpass [lindex $argv 1];


# opem shell
spawn $env(SHELL)
# send passwd command
send "passwd $username\n"
expect "New Password:"
send "$newpass\n"
expect "Re-enter new Password:"
send "$newpass\n"
expect eof"
expect "# "
send "exit\n"

I would suggest that you modify the expect script to suit your environment and call it from your main script passing the variables as I do - it's easier that way I think.
