SUMMARY: How to create password in the script? Version 2

I wrote the following script to create multiple user accounts that I would
like to share with the group (no expect needed). This script will do the
following:
1. Create user account
2. Reset/unlock the account (remove *LK* in the shadow file for that
account)
3. Create a encrypted password as 'pass123'. Field: 'n${ACCT}' is just key
generated (you can put anything in this field)
4. Put the password into /etc/shadow for each user account when created.

#!/usr/bin/sh

# Author: Stephanie
# This script creates multiple user accounts using the username text file.
#

echo "Home directory (/export/home/its): \c"
read DIR
echo "Belong to GROUP (oracle): \c"
read GROUP
echo "Account name text file (/tmp/acctname.txt): \c"
read USERFILE
while read ACCT
do
  useradd -d ${DIR}/${ACCT} -g ${GROUP} -s /bin/ksh -m -k /etc/skel/ ${ACCT}
  passwd -u ${ACCT} # unlock password and set to null
  PW=`perl -e '$x=crypt('pass123','n${ACCT}'); print $x'`
  perl -pi -e s/${ACCT}:/${ACCT}:${PW}/g /etc/shadow
done < ${USERFILE}

exit 0
