How do you use arrays in bash with an example?

Bash arrays are a powerful feature that allow you to store multiple values in a single variable. They can be either indexed or associative. Here's how you can use arrays in bash with an example:


        # Declare an array
        fruits=('apple' 'banana' 'orange')

        # Access elements
        echo ${fruits[0]}  # Outputs: apple
        echo ${fruits[1]}  # Outputs: banana

        # Loop through the array
        for fruit in "${fruits[@]}"; do
            echo $fruit
        done

        # Get the length of the array
        echo "Number of fruits: ${#fruits[@]}"
