Ping a range of numbered machines

c:\>for %t in (0 1 2 3 4 5 6 7) do for %d in (0 1 2 3 4 5 6 7 8 9) do ping -n 1 machine-0%t%d
%t are tens. %d are digits. One may have further outer loops to provide hundreds, thousands, etc. This example applies ping to the numbered machines. The pattern can be used in other ways to apply all combinations of components to a task.
