💡 Hint

Common Mistakes

Using '-eq' which checks for exact equality, not pattern matching.

Using '-like' which uses wildcard matching but is different from '-match'.

The '-match' operator checks if the string on the left contains the pattern on the right.

💡 Hint

Common Mistakes

Using '-like' which uses wildcards but not regex.

Using '-eq' which checks exact match.

The '-match' operator supports regular expressions, so '^a' matches words starting with 'a'.

D-eq

💡 Hint

Common Mistakes

Using '-like' which does not support regex.

Using '-contains' which is for collections, not strings.

The '-match' operator uses regex patterns like '\d+' to find digits in a string.

4fill in blank

hard

Fill both blanks to filter an array for strings that end with '.txt' using the match operator.

PowerShell

$files = @('doc1.txt', 'image.png', 'notes.txt', 'script.ps1')

Write-Output $txtFiles

B'\.txt$'

C'*.txt'

D-like

Attempts:

3 left

💡 Hint

Common Mistakes

Using '-like' with '*.txt' which works but is not the match operator.

Using '-match' with '*.txt' which is not a regex pattern.

Use '-match' with the regex '\.txt$' to find strings ending with '.txt'.

5fill in blank

hard

Fill all three blanks to create a hashtable of words and their lengths only if the word contains the letter 'e' using the match operator.

PowerShell

$words = @('tree', 'sky', 'bee', 'cloud')
$lengths = @{ }
foreach ($word in $words) {
    if ($word [1] [2]) {
        $lengths[[3]] = $word.Length
    }
}
Write-Output $lengths

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

A-match

B'e'

C$word

D-like

Attempts:

3 left

💡 Hint

Common Mistakes

Using '-like' instead of '-match' for regex matching.

Using a string literal instead of the variable as the hashtable key.

Use '-match' with pattern 'e' to check if the word contains 'e', then use the word as the key in the hashtable.
