💡 Hint

Common Mistakes

Using forward slashes in Windows paths.

Not quoting the path string properly.

In PowerShell, backslashes in strings must be escaped or use single quotes to treat them literally. Using single quotes with double backslashes is correct here.

💡 Hint

Common Mistakes

Not quoting the filename.

Using Get-Item instead of a path string.

The path must be a string, so it needs quotes. Without quotes, PowerShell treats it as a command or variable, causing an error.

4fill in blank

Fill both blanks to create a hashtable of files with their existence status for 'file1.txt' and 'file2.txt'.

PowerShell

$files = @{ 'file1' = Test-Path [1]; 'file2' = Test-Path [2] }

Drag options to blanks, or click blank then click option'

A'file1.txt'

B'file2.txt'

C'file3.txt'

D'file4.txt'

💡 Hint

Common Mistakes

Mixing file names or using wrong file names.

Not quoting the file names.

Each Test-Path call needs the correct file path as a string to check existence.

5fill in blank

hard

Fill all three blanks to create a filtered list of existing '.log' files from an array.

PowerShell

$logs = @('app.log', 'error.log', 'readme.txt') | Where-Object { Test-Path [1] } | ForEach-Object { $_.[2] } | Where-Object { $_.[3] -eq '.log' }

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Not building the path correctly for Test-Path.

Using wrong properties to get the file extension.

The code checks if the file exists by prepending './' to the filename, then extracts the file extension to filter '.log' files using Split-Path with the Extension property.
