Why arrays handle lists of data

📖 Scenario: You are organizing a list of your favorite fruits to share with friends using a Bash script.

🎯 Goal: Create a Bash script that uses an array to store a list of fruits, then prints them out one by one.

📋 What You'll Learn

Create an array called fruits with the exact values: apple, banana, cherry

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

Use a for loop with the variable fruit to iterate over the fruits array

Print each fruit on its own line

💡 Why This Matters

🌍 Real World

Arrays help you organize and manage lists of data easily in scripts, like keeping track of files, users, or settings.

💼 Career

Knowing how to use arrays in Bash is important for automating tasks and managing data efficiently in many IT and DevOps roles.

1

Create the fruits array

Create an array called fruits with these exact values: apple, banana, cherry

Bash Scripting

# Create an array called fruits with apple, banana, cherry
# Your code here

Need a hint?

Use parentheses () to create an array in Bash.

2

Count the number of fruits

Create a variable called count that stores the number of items in the fruits array using ${#fruits[@]}

Bash Scripting

fruits=(apple banana cherry)
# Create a variable count to hold the number of fruits
# Your code here

Need a hint?

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

3

Loop through the fruits array

Use a for loop with the variable fruit to iterate over the fruits array

Bash Scripting

fruits=(apple banana cherry)
count=${#fruits[@]}
# Use a for loop to go through each fruit
# Your code here

Need a hint?

Use "${fruits[@]}" to access all elements of the array.

4

Print the fruits

Print each fruit on its own line inside the for loop using echo "$fruit"

Bash Scripting

fruits=(apple banana cherry)
count=${#fruits[@]}
for fruit in "${fruits[@]}"; do
    # Print the fruit
    # Your code here
done
