Step-by-Step Guide to Creating a Simple Bash Quiz Game

1. Create a Bash Script File
Open a terminal and create a new file for your script. You can use any text editor, such as nano or vim. For example:

nano quiz_game.sh

2. Write the Script
Paste the following script into your file. This script represents a basic quiz game where users answer multiple-choice questions.

#!/bin/bash

# Define questions and answers
questions=(
    "What is the capital of France?"
    "Which planet is known as the Red Planet?"
    "What is the largest ocean on Earth?"
)

choices=(
    "A. Berlin B. Madrid C. Paris D. Rome"
    "A. Earth B. Mars C. Jupiter D. Saturn"
    "A. Atlantic B. Indian C. Arctic D. Pacific"
)

answers=(
    "C"
    "B"
    "D"
)

# Initialize score
score=0

# Iterate through questions
for i in "${!questions[@]}"; do
    echo "Question $((i + 1)): ${questions[$i]}"
    echo "${choices[$i]}"
    read -p "Enter your choice (A, B, C, D): " user_answer

    # Check if the answer is correct
    if [ "$user_answer" == "${answers[$i]}" ]; then
        echo "Correct!"
        ((score++))
    else
        echo "Incorrect. The correct answer was ${answers[$i]}."
    fi
    echo
done

# Show final score
echo "Quiz Over! Your final score is $score/${#questions[@]}."

3. Save and Exit
Save the file and exit the editor (Ctrl + X for nano, then Y to confirm and Enter).

4. Make the Script Executable
Change the file permissions to make the script executable:

chmod +x quiz_game.sh

5. Run the Script
Execute the script to play the quiz game:

./quiz_game.sh
