Question

Im trying to create a craps game on linux mint but im definitely not proficient with it. I'm a new student to this class and its done online. I seen a post that was already made with the exact question and requirements that I need to use for my script, but when I run the command it processes wrong, it goes like this... Name the script craps.sh The script will get 2 random numbers between 1-6. The script will display each number, and the sum. If the sum is 2, 3, or 12 the user loses. Print an appropriate message. If the sum is 7 or 11 the user wins. Print an appropriate message. If the sum is 4, 5, 6, 8, 9, 10 this becomes the "point". The user will keep "rolling" until they get the point (they win) or 7 (they lose). Print an appropriate message. Once the user has won or lost, ask if the user wants to try again. If so, start the game again. If not, exit. BONUS: +10 possible: Implement a wagering system. Before each initial roll ask the user how much they wish to wager, and keep track of how much they have won/lost. I have been trying to get this for days and can't figure it out... my professor won't help and doesn't provide a text book.

# craps.sh program inn bash shell

# $RANDOM returns a different random integer at each invocation.

# generate_random_number function which returns sum of

# 2 random number between 1 and 6

generate_random_number()

{

    RANGE=6

    #get 2 random numbers

    number1=$RANDOM

    number2=$RANDOM

    # get it between 1 and 6

    number1=$((($number1%$RANGE)+1))

    number2=$((($number2%$RANGE)+1))

    echo number 1 is $number1

    echo number 2 is $number2

    # add 2 numbers

    sum=$(($number1+$number2))

    echo sum is $sum

    #return the sum

    return $sum

}

# play_game() function invoked whenever user wants to play

play_game(){

    # first throw

    generate_random_number

    sum=$?

    # check if win or lost

    if(($sum==2 || $sum==3 || $sum==12))

    then

        # lost then subtract wager from total amount

        amount=$(($amount-$wager))

        echo You Lost $wager$

    fi

    if(($sum==7 || $sum==11))

    then

        # win then add wager to total amount

        amount=$(($amount+$wager))

        echo You Won $wager$ more

    fi

    if(($sum==4 || $sum==5 || $sum==6 || $sum==8 ||$sum==9 || $sum==10))

    then

        # store current sum as point and throw until point

        # appears or 7

        point=$sum

        generate_random_number

        value=$?

        while (( $value!=$point && $value!=7 ))

        do

            generate_random_number

            value=$?

        done

        # if point appears then win else lost

        if(($value==$point))

        then

            amount=$(($amount+$wager))

            echo You Won $wager$ more

        else

            amount=$(($amount-$wager))

            echo You Lost $wager$

        fi

    fi

    # user input to try again

    read -p "Try again?Y/N " again

    if [ "$again" = "Y" ]; then

        # play_game to play again

        play_game

        else

        # else display the total amount won or lost

        if(( $amount >= 0))

        then

            echo You Won $amount$

        else

            amount=$(($amount*-1))

            echo You Lost  $amount$

        fi

        echo bye

    fi

}

# initialize amount to 0

amount=0

# before first throw get the wager amount

read -p "Enter wager amount : " wager

play_game

echo
