📖 Scenario: You want to tell your friends about your favorite fruits by listing them one by one.

🎯 Goal: Write a bash script that uses a for loop to go through a list of fruits and print each fruit on its own line.

📋 What You'll Learn

Create a list of fruits in a variable called fruits

Use a for loop to go through each fruit in fruits

Print each fruit inside the loop

💡 Why This Matters

🌍 Real World

Listing items and processing them one by one is common in scripts that manage files, users, or tasks.

💼 Career

Knowing how to use for loops in bash helps automate repetitive tasks in system administration and DevOps roles.

1

Create a list of fruits

Create a variable called fruits that contains these exact fruits separated by spaces: apple banana cherry

Bash Scripting

# Create the fruits list variable
# Your code here

Need a hint?

Use quotes to assign multiple words to a variable in bash.

2

Set up a counter variable

Create a variable called count and set it to 0 to count how many fruits you print.

Bash Scripting

fruits="apple banana cherry"
# Create a count variable and set it to 0
# Your code here

Need a hint?

Just write count=0 on a new line.

3

Use a for loop to go through the fruits

Write a for loop using the variable fruit to go through each item in $fruits. Inside the loop, increase count by 1.

Bash Scripting

fruits="apple banana cherry"
count=0
# Write a for loop with variable fruit to go through $fruits
# Inside the loop, increase count by 1
# Your code here

Need a hint?

Use for fruit in $fruits; do ... done and count=$((count + 1)) inside.

4

Print each fruit inside the loop

Add a echo command inside the for loop to print the current fruit. Then print the total count after the loop.

Bash Scripting

fruits="apple banana cherry"
count=0
for fruit in $fruits; do
    count=$((count + 1))
    # Print the current fruit
    # Your code here
done
# Print the total count
# Your code here

Need a hint?

Use echo "$fruit" inside the loop and echo "Total fruits: $count" after.
