powershell whereis first draft

whereis.ps1

function get-path{
	$env:path -split';'
}

function whereis 
{
	$argument = $cmd, [string]$arguments = $args;
	foreach ($item in get-path){
		foreach ($thing in gci $item -ErrorAction silentlycontinue){
			if($thing.Name.StartsWith($cmd + ".")){
				echo $item;
			}
			
		}
	}
}

it's not 100%, but was good enough to find what I wanted. will maybe consider improving it...
