Can I Pass Arguments To A Powershell Function The Unix Way?

Question

I have a PowerShell function that basically looks like this:

function DoSomething-ToTask {
    [cmdletbinding()]
    param(
          [parameter(Mandatory=$t

Yes, you can use the ValueFromRemainingArguments parameter attribute.

function DoSomething-ToTask {
    [cmdletbinding()]
    param(
          [Parameter(Mandatory=$true, ValueFromRemainingArguments = $true)]
          [int[]]$TaskNums
    )

    foreach ($TaskNum in $TaskNums) {
        do something $TaskNum
    }
}

Here is a working example:

function Do-Something { 
    [CmdletBinding()]
    param (
        [Parameter(ValueFromRemainingArguments = $true)]
        [int[]] $TaskNumber
    )

    foreach ($Item in $TaskNumber) {
        Write-Verbose -Message ('Processing item: {0}' -f $Item);
    }
}

Do-Something 1 2 3 -Verbose;

Result:
