💼 Career

Knowing how to find and filter commands helps system administrators and automation engineers write effective scripts.

1

Create a search keyword variable

Create a variable called $keyword and set it to the string Get.

PowerShell

# Create a variable called $keyword and set it to 'Get'
# Your code here

Need a hint?

Use $keyword = 'Get' to create the variable.

2

Use Get-Command with the keyword

Create a variable called $commands and set it to the result of Get-Command using the -Name parameter with $keyword and a wildcard * after it (like $keyword*).

PowerShell

$keyword = 'Get'
# Create a variable $commands to store Get-Command results using $keyword*
# Your code here

Need a hint?

Use Get-Command -Name "$keyword*" to find commands starting with the keyword.

3

Filter commands by command type

Filter $commands to only include commands where the CommandType property equals Cmdlet. Store the filtered list back in $commands.

PowerShell

$keyword = 'Get'
$commands = Get-Command -Name "$keyword*"
# Filter $commands to only Cmdlet type commands
# Your code here

Need a hint?

Use Where-Object { $_.CommandType -eq 'Cmdlet' } to filter the commands.

4

Display the filtered commands

Use Write-Output to display the Name property of each command in $commands.

PowerShell

$keyword = 'Get'
$commands = Get-Command -Name "$keyword*"
$commands = $commands | Where-Object { $_.CommandType -eq 'Cmdlet' }
# Display the Name of each command in $commands
# Your code here

Need a hint?

Use ForEach-Object { Write-Output $_.Name } to print each command name.
