💡 Hint

Common Mistakes

Using 'Name' or 'FullName' which do not exist on the object returned by Get-Location.

Using 'Directory' which is not a property of the location object.

The Path property of the object returned by Get-Location shows the current directory path as a string.

💡 Hint

Common Mistakes

Including quotes inside the blank which causes the name to be a string literal with quotes.

Using a path format like '/TestFolder' which is not needed here.

The -Name parameter expects the folder name as a string without quotes in PowerShell scripts. Quotes are optional but not required here.

C<

DSize

💡 Hint

Common Mistakes

Using 'Size' which is not a property of file objects in PowerShell.

Using '<' instead of '>' which filters smaller files.

The Length property gives the file size in bytes. Using > filters files larger than 1MB.

hard

Fill all three blanks to create a hashtable of file names and their sizes for files modified in the last 7 days on macOS PowerShell.

PowerShell

$recentFiles = @(); foreach ([2] in (Get-ChildItem -File | Where-Object { $_.LastWriteTime -gt (Get-Date).AddDays(-7) })) { $recentFiles += @{ [1] = $[2].Name; [3] = $[2].Length } }

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

Bfile

CSize

Ditem

💡 Hint

Common Mistakes

Using inconsistent variable names in the loop and hashtable.

Using 'Length' as a key instead of 'Size'.

The variable item is used in the loop. The hashtable keys are Name and Size, and values come from item.Name and item.Length.
