create user script from file

[nikkon]

hi.
i have a small bash script who read for example a file .txt with user name and make the user and set even a password.

#!/bin/sh
for i in `more userlist.txt `
do
echo $i
echo $i”123″ | passwd –stdin “$i”
echo; echo “User $username’s password changed!”
done

the problem is that now for each user i must set a diferent UID and group.I will have direfernt files for example :
user.txt UID.txt group.txt

the file format is like this :
user1
user2
....


Thank you for help.

You'll need to create the user (useradd) before you can set the password, and by default Linux will give each user a different uid and gid anyway. If you really want to specify the uid and gid, you'd be better having a single file with the three values for each user on a line (eg "user1 501 500"), then you can read the file line by line in a while loop and do what you have to really easily.
