I'm trying to figure out how to stop processing the inner loop in my PowerShell script and move on to the next iteration of the outer loop. Here's the code I'm working with:
```
1..3 | ForEach-Object {
"Outer $_"
1..5 | ForEach-Object {
if ($_ -eq 3) { continue }
"Inner $_"
}
}
```
I want the output to look like this:
```
>Outer 1
> Inner 1
> Inner 2
>Outer 2
> Inner 1
> Inner 2
>Outer 3
> Inner 1
> Inner 2
```
But currently, my code halts operations after the first `continue`. I tried using `return`, but it only stops the current inner loop instead of moving on to the next outer loop. Any suggestions would be greatly appreciated! Thanks!

This can get tricky. Since `ForEach-Object` is a cmdlet and not a traditional loop, you can't use keyword control statements like `break` in the same way. I'm thinking the best approach is to redesign your looping logic. You could either use standard `foreach` loops as follows:
```powershell
:outer foreach($outer in 1..3){
"Outer $outer"
foreach($inner in 1..5){
if($inner -eq 3){ continue outer }
"Inner $inner"
}
}
```
Or, if you need to stick with pipeline structures, consider using a `do-while` loop as a workaround. Just be careful, it's a hack and might look a bit funny in the code review!
You can use `return` inside the inner block because `ForEach-Object` works differently. Instead of `continue`, which doesn't behave as expected here, just `return` from the inner loop to skip to the next iteration of the outer loop. Remember, the behavior might be surprising, but once you get it, it's manageable.
