Login script...Need help asap

[chicagorush]

I'm in a bit of trouble right now. I have a project due for my class (linux/unix 101 stuff) and it involves scripting. I'm horrible at it and don't know what to do.

Ok to start off i have a project that has to deal with creating a company with 17 different users and making a file/directory system. Also i have to create a shell script with a login screen and a menu with submenus.

I'm currently stuck on how to create the login screen from reading the users from the folder i put the users in. Then i don't know how to make it so when they put their user name and password in, it goes from the login screen to the "main menu" that i had made after they have a successful login.

Here are my codes right now.

This is my login screen.

tput cup $1 $2
tput clear
bold=`tput smso`
offbold=`tput rmso`
echo $bold
tput cup 10 20; echo "User ID:"
tput cup 12 20; echo "Password:"
echo $offbold
tput cup 10 41; read userid
tput cup 12 41; read password

here is my main menu screen:

 while :
 do
    clear
    echo "-------------------------------------"
    echo " Main Menu "
    echo "-------------------------------------"
    echo "[1] Customer Information"
    echo "[2] Employee Information"
    echo "[3] Search"
    echo "[4] User settings"
    echo "[6] Exit"
    echo "======================="
    echo -n "Enter your choice [1-5]: "
    read yourch
    case $yourch in
      1) echo "Taking you to customer infomation...Please wait." ; read ;;
      2) echo "Taking you to employee infromation...Please wait." ; read ;;
      3) echo "Taking you to search." ; read ;;
      4) echo "User settings." ; read ;;
      5) exit 0; ;;
      *) echo "Please select choice 1,2,3,4, or 5";
         echo "Press a key. . ." ; read ;;
 esac
done

Now i don't know where to go from there. I want to "join" the 2 files so that once the users login's with the correct password and user name they can see the menu screen. The last parts on the menu screen i just put there until i find a way to make the choice selection go from when you press 1 or 2 or 3 to another script that has the information on it.

If anyone can help me with this that would be great. I would like to get this done asap.
Also i'm having some problems with the users. If anyone has any better way to configure a users group to join in with the scripts please let me know.

Thanks

You might want to look into using dialog for the menus.

[chicagorush]

what do you mean dialog?

oh and i found out how to configure it so that i can make it go to the next script.

but now my real trouble is to get it so that a users has to login to access this stuff and if the user doesn't log in with the correct password and name it comes up with a thing saying incorrect user/password please try again and refreshes that screen.
