# ping -h
Usage: ping [-aAbBdDfhLnOqrRUvV] [-c count] [-i interval] [-I interface]
            [-m mark] [-M pmtudisc_option] [-l preload] [-p pattern] [-Q tos]
            [-s packetsize] [-S sndbuf] [-t ttl] [-T timestamp_option]
            [-w deadline] [-W timeout] [hop1 ...] destination
# man ping

       -c count
              Stop after sending count ECHO_REQUEST packets.

       -f     Flood ping. 

       -s packetsize
              Specifies the number of data bytes to be sent. 

       -i interval
              Wait  interval  seconds between sending each packet.
              The default is to wait for one second between each packet normally, or not to wait in flood mode.

       -w deadline
              Specify a timeout, in seconds, before ping exits regardless of how many packets have been sent or received.

       -R     ping only.  Record route.
