💡 Hint

Common Mistakes

Choosing 'Name' which only shows the folder name, not full path.

Using 'Length' or 'Mode' which are unrelated properties.

The Path property shows the full current directory path in PowerShell.

💡 Hint

Common Mistakes

Using '-Filter' which is a parameter for Get-ChildItem, not Where-Object.

Using '-Property' which is not valid for Where-Object.

The -FilterScript parameter is used with Where-Object to filter files by a script block.

💡 Hint

Common Mistakes

Including quotes around the directory name.

Using a path starting with '/' which is not needed here.

On Linux PowerShell, the -Name parameter expects the directory name without quotes.

PowerShell

Get-Content [1] | Where-Object { $_ [2] 'error' }

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

B-like

C-match

Dlog

💡 Hint

Common Mistakes

Using '-like' which is for wildcard matching, not regex.

Using 'log' instead of the full file name.

Get-Content reads the file 'log.txt'. The -match operator filters lines containing 'error'.

5fill in blank

hard

Fill all three blanks to create a hashtable with file names as keys and their sizes as values for files larger than 1KB.

PowerShell

$files = Get-ChildItem -File | Where-Object { $_.Length [1] 1024 }
$sizes = @{}
foreach ($file in $files) { $sizes[[2]] = [3] }

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

A>

B$file.Name

C$file.Length

D<

💡 Hint

Common Mistakes

Using '<' instead of '>' causing wrong files to be selected.

Swapping keys and values in the hashtable.

The code filters files larger than 1024 bytes using >. The hashtable uses file.Name as keys and file.Length as values.
