The host address and round-trip times for each pair of packets are displayed. Outputs packets as fast as they come back or one hundred times per second, whichever is more. This provides a rapid display of how many packets are being dropped. Only the super-user may use this option. This can be very hard on a network and should be used with caution.
Pause wait seconds between sending each query packet.
By de- fault, ping waits one second between each packet. If preload is specified, ping sends that many packets as fast as possible before continuing in its normal mode. Numeric output only. No attempt will be made to lookup symbolic names for host addresses. This is useful for diagnosing data-dependent problems in a network.
