How to use bash shell to create many users

Hi all, my name is Rick. I¡¦m using red hat 9.0
Can somebody show me how to add many accounts by a bash script?

I need to perform the following functions:
1) I have a file called userfile.txt. It contains new users¡¦ information. The format is like this:
Username1assword:groupname:username1 surname1
e.g. Mike:1234:IT:Mike White
John:5732:Accounting:John Smith
¡K¡K

2) I now need to create a shell script called¡Xmyscript , this script program will read the userfile.txt file and process the user account.
„X To use this program, user must type this command: ¡§myscript userfile.txt¡¨. If user does not type in this way, system will display the error message¡X¡§you type in wrong way !¡¨
„X If people type in myscript ¡Vh, system will display some information to the users.

You'll have to edit it a bit, but this should help.
