how to creat linux users without interact with the console?

Dear experts,
I have following requirements:
I must create much users in the centos linux server.
I can do it manually with useradd and passwd command.
But since i have this action done hundreds of times, is there any script who can create the
user and set his password without any interact with console?

Thanks a lot for your valuable information.

Best Regards,
Robert

You have a file with username encrypted_password group
cat filename | while read a b c ; do
If  ( grep "$a" "/etc/passwd" >/dev/null) ; then
 echo alread exists
else
echo useradd -g $c -m -d /home/$a -p "$b" $a
fi
done

If the output is in the correct format, remove echo and let it run
