Parameters with prompts

    Hi all

    I'm new to Powershell and Google didn't turn up anything useful (or that I could get working) so I'm here asking for help.

    I've got a script that requires parameters but I'd like a slightly better prompt than the one I'm getting.

    This is my parameters:-
    [Parameter(Mandatory=$True] [string]$servername, # this is server to upload to

    This gives me a prompt of:
    servername:

    What I'd like to do is have a prompt of :-
    Enter a server name:
    but I'm not sure how to go about it.

    I don't want to use Read-Host as I want to be able to call this from the command line.

    I've tried:-
    [Parameter(Mandatory=$True,HelpMessage="Enter a server name")] [string]$servername, # this is server to upload to
    but it doesn't change the prompt.

    Can I do what I want and, if so, where am I going wrong?

    Remove the Mandatory=$True
    Then check if servername was entered on the command line.  If not use read-host to get it with your custom prompt.
    if (! $servername) { $servername = read-host "Enter a server name...?" }
