diagtext = cmd;

split = Regex.Split(diagtext, @"%");

foreach (var item in split)
{
   diskmem = split[10];
}

```

So I have this long string called `cmd` and I'm using regex to display a particular string next to the percentage `%` (sign). I was able to display this string: `/ run / user / 1000total 120G 15G 105G 13 %`, but I only need the `13` not the strings before `13`.

How can I do this?
