Indexed array declaration in Bash Scripting - Mini Project: Build & Apply

Indexed array declaration

📖 Scenario: You are organizing a list of your favorite fruits to use in a script that will later process them.

🎯 Goal: Create an indexed array in Bash with specific fruit names, then display the array contents.

📋 What You'll Learn

Create an indexed array named fruits with exact values

Add a variable to hold the number of fruits

Use a loop to print each fruit with its index

Print the total number of fruits at the end

💡 Why This Matters

🌍 Real World

Arrays help organize lists of items like filenames, user inputs, or settings in scripts.

💼 Career

Knowing how to use arrays in Bash is essential for automating tasks and managing data in system administration and DevOps roles.

1

Create the indexed array

Create an indexed array called fruits with these exact values in order: Apple, Banana, Cherry, Date, Elderberry.

Bash Scripting

# Create the indexed array fruits with the given fruits
# Your code here

Need a hint?

Use parentheses () to declare an indexed array in Bash.

2

Add a variable for the number of fruits

Create a variable called count that stores the number of elements in the fruits array.

Bash Scripting

fruits=(Apple Banana Cherry Date Elderberry)
# Create count variable to hold number of fruits
# Your code here

Need a hint?

Use ${#array[@]} to get the length of an array in Bash.

3

Loop through the array and print each fruit

Use a for loop with variable i from 0 to count - 1 to print each fruit with its index in the format: Fruit 0: Apple.

Bash Scripting

fruits=(Apple Banana Cherry Date Elderberry)
count=${#fruits[@]}
# Loop from 0 to count-1 and print each fruit with its index
# Your code here

Need a hint?

Use a C-style for loop in Bash to iterate over array indices.

4

Print the total number of fruits

Print the total number of fruits using the count variable in the format: Total fruits: 5.

Bash Scripting

fruits=(Apple Banana Cherry Date Elderberry)
count=${#fruits[@]}
for ((i=0; i<count; i++)); do
    echo "Fruit $i: ${fruits[i]}"
done
# Print total number of fruits
# Your code here

Need a hint?

Use echo to print the total count variable.
