Are those passwords encrypted? If they are not encrypted, you may need to encrypt passowrds first because the command to assign the password for a user use encrypted password. I assume that 1st and 2nd fields in passwd.1 are with the same format as /etc/passwd
user_account_name:encrypted_password
You will let the system to select UID and you will use default group id (otherwise, you can use -u UID -g GID in useradd command to define UID and GID):

#!/usr/bin/ksh

while read line
do
uname=`echo $line|cut -d":" -f1`
passwd=`echo $line|cut -d":" -f2`
useradd -m $uname
/usr/sam/lbin/usermod.sam -p $passwd
done < passwd.1

exit

Thanx for your reply.
The password is not encripted.I perfer not to use usermod.sam because I need to do the same excercise on my linux file server also.Is there any common shell script which can do this?

Hi, Jerry, If you want to run the same script on both HPUX and Linux. You may have a look at "expect" http://wiki.tcl.tk/201

Hey;

If you want to put the password in on an HP box w/o the use of expect, you're stuck with usermod.sam or ueradd.sam. How you differentiate between Linux and HPUX is through a variable:

Os=$(uname -s)
[[ "${Os}" = "HP-UX" ]] && Useradd=/usr/sam/lbin/useradd.sam || \
Useradd=/usr/sbin/useradd
uid=1000

cat passwd.1 | while read user pwd
do
printf "%-8s %s\n" ${user} ${pwd}
${Useradd} -u ${uid} -g users -c "test user" -d /home/${user} \
-p ${pwd} -s /bin/ksh ${user}
mkdir -p -m 755 /home/${user}
cp /etc/skel/.[A-z]* /home/${user}
chown -R ${user}:users /home/${user}
uid=$((uid+1))
done

Hi!

You can try this for adding users:

while read username password
do
useradd [options] ${username}
done < your_file

Still thinking about how to automatically assign passwords to new user.
