Ping commands and parameter

There is no meaning because the Windows ping command just ignores any additional characters when the first is a known option.

You can check this with options requiring an additional parameter:

ping -n 2 dest
ping -n1 2 dest

Both will perform the same action (send two requests) and

ping -n1 dest

prints an error message.

This differs from typical Unix command line utilities where multiple options can be concatenated and option parameters can be passed together with the command.
