Break and continue in PowerShell - Mini Project: Build & Apply

Using Break and Continue in PowerShell Loops

📖 Scenario: You are managing a list of daily tasks. You want to process these tasks one by one but stop processing when you find a specific task. Also, you want to skip certain tasks that are not important.

🎯 Goal: Build a PowerShell script that loops through a list of tasks, skips unimportant tasks, and stops processing when a specific task is found.

📋 What You'll Learn

Create a list of tasks with exact names

Create a variable to hold the task to stop at

Use a foreach loop to go through the tasks

Use continue to skip unimportant tasks

Use break to stop when the stop task is found

Print the tasks that are processed

💡 Why This Matters

🌍 Real World

Automating task processing where some tasks need to be skipped and processing stops at a certain point.

💼 Career

Understanding break and continue is essential for controlling loops in scripts used for automation, data processing, and system administration.

1

Create the list of tasks

Create a list called $tasks with these exact tasks: 'Email', 'Meeting', 'Coffee', 'Report', 'Lunch'.

PowerShell

# Create the list of tasks
# Your code here

Need a hint?

Use @() to create an array in PowerShell.

2

Set the stop task

Create a variable called $stopTask and set it to the string 'Report'.

PowerShell

$tasks = @('Email', 'Meeting', 'Coffee', 'Report', 'Lunch')
# Create the stop task variable
# Your code here

Need a hint?

Use = to assign the string 'Report' to $stopTask.

3

Loop with break and continue

Write a foreach loop using $task to go through $tasks. Inside the loop, use continue to skip the task 'Coffee'. Use break to stop the loop when $task equals $stopTask. For other tasks, print $task.

PowerShell

$tasks = @('Email', 'Meeting', 'Coffee', 'Report', 'Lunch')
$stopTask = 'Report'
# Write the foreach loop with break and continue
# Your code here

Need a hint?

Use foreach ($task in $tasks) to loop. Use if statements to check tasks. Use Write-Output to print.

4

Print the processed tasks

Run the script to print the tasks processed before stopping. The output should show Email and Meeting only.

PowerShell

$tasks = @('Email', 'Meeting', 'Coffee', 'Report', 'Lunch')
$stopTask = 'Report'
foreach ($task in $tasks) {
    if ($task -eq 'Coffee') {
        continue
    }
    if ($task -eq $stopTask) {
        break
    }
    Write-Output $task
}
# Run the script to see output

Need a hint?

Run the script and check the output shows only Email and Meeting.
