Returning a value from within a ForEach in Powershell
It looks like you are calling ForEach (a function in [System.Array]) with a parameter which is a scriptblock. Essentially, you are defining and returning { Return $_ } every iteration of the loop.
This means ReturnStuff will capture output each time, and because this function does nothing with the output of this line, all the output is returned:
$a.ForEach{ return $_ }This behavior is similar to $a | Foreach-Object { return $_ }
So what to do?
Use a
ForEachloop instead (not to be confused withForeach-Object):ForEach ($item In $a) { return $item }Select the first value returned from all the scriptblocks:
$a.ForEach{ return $_ } | Select -First 1
