Need Help!!!

This is my script!
#Get information from userlist file!
cat ${NEW_USERS} | \
while read USER PASSWORD GROUP FULLNAME

#Process adding users and groups, also shows information after users have been added!
do
if [ -z "`grep ^${GROUP}: /etc/group`" ];then
groupadd ${GROUP}
echo "Group ${GROUP} successfully added."

fi
if [ -z "`grep ^${USER}: /etc/passwd`" ] && [ ${#USER} -lt 6 ] && [ ${#PASSWORD} -ge 5 ];
then
useradd -g ${GROUP} -p ${PASSWORD} -c ${FULLNAME} -m -d ${HOME_BASE}${USER} ${USER}

echo "User ${USER} successfully added."

else
echo "Can not add user ${USER}--"The user has existed or invaild!!""

fi
The Problem is I just can read the format like: USER PASSWORD GROUP FULLNAME in userlist file
but if I changed the format like: USER:PASSWORD:GROUP:FULLNMAE, then it doesn't work, so how I could I read this format,please give me a hint, I used gawk,but still doesn't work!

Seems like you should be able to use some variation of the following to get the results you want...

Code:

x=0
while [ $x -lt `wc -l | sed 's/[^0-9]//g'` ] ; do
USER=`awk -v var=$x -F":" 'NR==var {print $1}' $NEW_USERS_FILE`
PASSWORD=`awk -v var=$x -F":" 'NR==var {print $2}' $NEW_USERS_FILE`
GROUP=`awk -v var=$x -F":" 'NR==var {print $3}' $NEW_USERS_FILE`
FULLNAME=`awk -v var=$x -F":" 'NR==var {print $4}' $NEW_USERS_FILE`
# ...
# do whatever you need to do with the variables
# ...
x=$x+1
done

Hope this helps (I'm a bit of a newbie, so it certainly might not.
