for loop with range ({1..10}) in Bash Scripting - Mini Project: Build & Apply

Counting Numbers with a Bash For Loop

📖 Scenario: Imagine you want to count from 1 to 10 using a simple script. This is like counting steps as you walk up a staircase.

🎯 Goal: You will write a Bash script that uses a for loop with a range {1..10} to print numbers from 1 to 10, one number per line.

📋 What You'll Learn

Create a Bash script variable to hold a greeting message.

Create a variable to hold the range of numbers from 1 to 10.

Use a for loop with the range {1..10} to print each number.

Print the greeting message before the numbers.

💡 Why This Matters

🌍 Real World

Counting or looping through numbers is common in scripts that automate tasks like backups, monitoring, or batch processing files.

💼 Career

Knowing how to use loops and ranges in Bash is a basic skill for system administrators, DevOps engineers, and anyone automating tasks on Linux or Unix systems.

1

Create a greeting message variable

Create a Bash variable called greeting and set it to the exact text "Counting from 1 to 10:".

Bash Scripting

# Create a variable called greeting with the text "Counting from 1 to 10:"
# Your code here

Need a hint?

Use variable_name="text" to create a string variable in Bash.

2

Create a variable for the number range

Create a Bash variable called numbers and set it to the range {1..10} exactly as numbers="{1..10}".

Bash Scripting

greeting="Counting from 1 to 10:"
# Create a variable called numbers with the value "{1..10}"
# Your code here

Need a hint?

Remember to put the range in quotes to assign it as a string.

3

Use a for loop with the range to print numbers

Write a for loop using for i in {1..10} to print each number i on its own line using echo.

Bash Scripting

greeting="Counting from 1 to 10:"
numbers="{1..10}"
# Use a for loop with 'for i in {1..10}' to print each number
# Your code here

Need a hint?

The loop starts with for i in {1..10}, then do, then the commands, and ends with done.

4

Print the greeting and the numbers

Add a line to print the greeting variable before the loop using echo "$greeting".

Bash Scripting

greeting="Counting from 1 to 10:"
numbers="{1..10}"
# Print the greeting message
# Your code here
for i in {1..10}
do
  echo "$i"
done

Need a hint?

Use echo "$greeting" before the loop to show the message.
