Call powershell function in file without dot sourcing

Question

Is this possible if I only have one function in the file named the same as the file? I seem to remember reading about it before. Something like this:

hello.ps1

Answer 1

I would get rid of the function call altogether. You don't lose named parameters and cmdlet wrapping at all. So this:

 function Hello
 {
    [CmdletBinding()]
    param(
       [Parameter(Mandatory=$true)]
       $Message
    )
    Write-Host "Hello, $Message!"
 }

becomes:

 [CmdletBinding()]
 param(
    [Parameter(Mandatory=$true)]
    $Message
 )
 Write-Host "Hello, $Message!"

And you can all it like this:

> .hello.ps1 "World"
