Verbose and debug output in PowerShell - Mini Project: Build & Apply

Verbose and debug output

📖 Scenario: You are writing a PowerShell script to process a list of files. You want to add messages that help you see what the script is doing and find problems if they happen.

🎯 Goal: Learn how to use verbose and debug messages in PowerShell scripts to show extra information and help with troubleshooting.

📋 What You'll Learn

Create a list of file names in a variable called $files.

Add a variable called $count to count files processed.

Use Write-Verbose to show a message for each file processed.

Use Write-Debug to show a debug message for each file.

Print the total count of files processed at the end.

💡 Why This Matters

🌍 Real World

Verbose and debug messages help script writers see what their script is doing and find problems quickly. This is useful when scripts get bigger or more complex.

💼 Career

Many IT and automation jobs require writing scripts that are easy to troubleshoot. Knowing how to add verbose and debug output is a key skill for maintaining and improving scripts.

1

Create a list of files

Create a variable called $files and assign it an array with these exact file names: "file1.txt", "file2.txt", "file3.txt".

PowerShell

# Create the $files array with the given file names
# Your code here

Need a hint?

Use @() to create an array in PowerShell.

2

Add a counter variable

Add a variable called $count and set it to 0 to count how many files are processed.

PowerShell

$files = @("file1.txt", "file2.txt", "file3.txt")
# Create a $count variable and set it to 0
# Your code here

Need a hint?

Just assign 0 to $count.

3

Add verbose and debug messages in a loop

Use a foreach loop with variable $file to go through $files. Inside the loop, increase $count by 1. Use Write-Verbose to print "Processing file: $file" and Write-Debug to print "Debug: Starting file $file".

PowerShell

$files = @("file1.txt", "file2.txt", "file3.txt")
$count = 0
# Loop through $files with foreach and add verbose and debug messages
# Your code here

Need a hint?

Use $count++ to add 1 to the count inside the loop.

4

Print the total count of files processed

After the loop, write a line to print "Total files processed: " followed by the value of $count using Write-Output.

PowerShell

$files = @("file1.txt", "file2.txt", "file3.txt")
$count = 0
foreach ($file in $files) {
    $count++
    Write-Verbose "Processing file: $file"
    Write-Debug "Debug: Starting file $file"
}
# Print the total files processed
# Your code here

Need a hint?

Use Write-Output to show the final count.
