Bulk User Adding For Qmail Toaster

Greetings, With help from the script PakOgah sent me I have created a bulk user adding script! It reads a text file which has entries like FIRSTNAME LASTNAME USERNAME And automatically adds the users in the text file, creates a comment field sets a default quota and password Suggestions are welcome. The script is attarched. Its still missing some functionality but its work in progress Kisakye ALex akisakye@ucu.ac.ug

#  BULK USER ADDING FOR QMAIL TOASTER
#
# Created after I ran into an issue of creating 20,000 users on my toaster!
# Initial ideas come from a script that PakOgah "pakogah@pala.bo-tak.info"
# helped me with.
# Still very manual, but Work in Progress
#
# Suggestions to akisakye@ucu.ac.ug
#
# Change a few variables and you are good to go
#
#
# Location of the users file
# Rememeber that the users file is in the format
# Firstname Lastname Username
USERS_FILE="/path/to/file.txt"
# The mail domain to which users are created
#
MAILDOMAIN="@domain.com"
# the vadduser command
QMAILADD="/home/vpopmail/bin/vadduser"
# Select a default password for all users
PASS="mypass"
#Specify the Default Quota_in_bytes for your Users
# 10 MB = 10 x 1024 x 1024
QUOTA="10485760"
#Fun starts here No more variables to change below this line
cat ${USERS_FILE} | \
while read FIRSTNAME LASTNAME USERNAME
do
  echo "adding the user: $USERNAME"
        $QMAILADD -q $QUOTA -c "$FIRSTNAME $LASTNAME" $USERNAME$MAILDOMAIN $PASS
done
