Shell concept (Bash, Zsh) in Linux CLI - Mini Project: Build & Apply

Basic Shell Scripting with Variables and Loops

📖 Scenario: You are learning how to automate simple tasks in the Linux shell using Bash or Zsh. Imagine you want to keep track of your favorite fruits and print a message for each one.

🎯 Goal: Create a shell script that stores a list of fruits, sets a greeting message, loops through the fruits, and prints a personalized message for each fruit.

📋 What You'll Learn

Create a variable called fruits containing the exact list: apple, banana, cherry

Create a variable called greeting with the exact text: "I love"

Use a for loop with variable fruit to iterate over fruits

Print the message combining greeting and fruit exactly as shown

💡 Why This Matters

🌍 Real World

Shell scripts like this help automate repetitive tasks such as processing lists of files, users, or data entries.

💼 Career

Basic shell scripting is essential for system administrators, developers, and anyone working with Linux servers or automation.

1

Create the list of fruits

Create a variable called fruits and assign it the exact string: "apple banana cherry"

Linux CLI

# Create the variable fruits with the exact value
# Your code here

Need a hint?

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

2

Add a greeting message

Create a variable called greeting and assign it the exact text: "I love"

Linux CLI

fruits="apple banana cherry"
# Create the variable greeting with the exact value
# Your code here

Need a hint?

Remember to use quotes for strings with spaces.

3

Loop through the fruits

Use a for loop with variable fruit to iterate over fruits and inside the loop print the message combining greeting and fruit separated by a space.

Linux CLI

fruits="apple banana cherry"
greeting="I love"

# Use a for loop to iterate over fruits
# Inside the loop, print the greeting and fruit
# Your code here

Need a hint?

Use for fruit in $fruits; do ... done and echo to print.

4

Run the script and see the output

Run the script and print the output. The output should show each fruit with the greeting on its own line.

Linux CLI

fruits="apple banana cherry"
greeting="I love"

for fruit in $fruits; do
    echo "$greeting $fruit"
done

# Run the script to print the output
# Your code here

Need a hint?

Run the script in your shell or use bash script.sh if saved in a file.
