I was referring to the help for Get-Help cmdlet but unable to understand the use of -Functionality parameter present with Get-Help.
When I see the details about the same I see:
PS C:\Temp> help Get-Help -Parameter Functionality -Functionality Displays help for items with the specified functionality. Enter the functionality. Wildcard characters are permitted.
This doesn't explain clearly what does that mean. I don't see any example to see how it works.
Can someone please help me understand this?
Pretty sure it's useless – I'll ashamedly admit that I've never put much effort into figuring it out. In PS v5.1 I get an error when I try to run it:
PS C:\> get-help -Functionality help get-help : Unable to find type [System.Windows.Forms.Keys]. At line:1 char:1 + get-help -Functionality help + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : InvalidOperation: (System.Windows.Forms.Keys:TypeName) [Get-Help], RuntimeException + FullyQualifiedErrorId : TypeNotFound,Microsoft.PowerShell.Commands.GetHelpCommand
I also like that the documentation tells you it accepts wildcard character, and then contradicts itself:
PS C:\> get-help get-help -Parameter functionality -Functionality Displays help for items with the specified functionality. Enter the functionality. Wildcard characters are permitted. This parameter has no effect on displays of conceptual ("About_") help. Required? false Position? named Default value None Accept pipeline input? False Accept wildcard characters? false
I thought I am the only one who didn't know the usage of this parameter. I was training few candidates on PowerShell and someone asked me what is the use of this parameter during the class and I was stumbled. I told him that I don't know and I will find out and let them know.
Still, I can't find the answer 🙂
