I saw THIS posting over on Mark Minasi’s forums that caught my eye.  It gives you a random help file under the motto of: “A powershell help file a day, keeps Don Jones away”.  🙂

Don responded pointing out one of our new V2 cmdlets:  Get-Random.  Since that cat is out of the bag and Get-Random is so cool, let’s explore it:

PS>Get-Help Get-Random


    Gets a random number or selects objects randomly from a collection.

    Get-Random [-Count [<Uint32>]] [[-InputObject] [<psobject>]] [-SetSeed [<in
    t>]] [<CommonParameters>]

    Get-Random [-Minimum [<Object>]] [[-Maximum] [<Object>]] [-SetSeed [<int>]]

    The Get-Random cmdlet gets a randomly selected number. If you submit a coll
    ection of objects to Get-Random, it gets one or more randomly selected obje
    cts from the collection.

    Without parameters or input, “Get-Random” returns a randomly selected 32-bi
    t unsigned integer between 0 and Int32.MaxValue (0x7FFFFFFF, 2,147,483,647)

    You can use the parameters of Get-Random to specify a seed number, minimum
    and maximum values, and the number of objects returned from a submitted col


    For more information, type: “get-help Get-Random -detailed”.
    For technical information, type: “get-help Get-Random -full”.

At the end of the day, the cmdlets that manage the OS features need to come from those feature teams so you should not expect PowerShell to deliver a ton of those.  For instance, the AD team needs to deliver the AD cmdlets, the network team needs to deliver networking Cmdlets.  If you are not getting the cmdlets you need, you should knock on the doors of those feature teams.  Don’t suffer in silence, complain.

PowerShell will deliver some management cmdlets but by and large, we are going to focus our efforts on utility cmdlets that work against anyones objects and make it a good deal for those feature teams to develop cmdlets.  Get-Random is just such a cmdlet.  I’ll bet you a dollar to a doughnut that no feature team would ever prioritize Get-Random but it turns out that all of their customers will use it at some point.  PowerShell delivers it and thus the feature team’s customers benefit.  That’s the deal – you invest in writting cmdlets/providers and we invest in ensuring that that was a great investement by delivering a ton of functions to your customers.  How can you go wrong with that?
