Power of PING

In our respective interactions with various networks accessible to us.....as administrators we keep pinging so many IPs for testing the connectivity at various times like ping 192.121.23.1 etc....and we get a response...but ping it self has so many switches that most of us hardly use......i came across a chart today that in a summarized form tells the switches of ping command with examples and a brief explanation.....sharing here with you...thanks http://www.activexperts.com

ping -c count	ping -c 10	Specify the number of echo requests to send.
Ping -d	ping -d	Set the SO_DEBUG option.
Ping -f	ping -f	Flood ping. Sends another echo request immediately after receiving a reply to the last one. Only the super-user can use this option.
Ping host	ping 121.4.3.2	Specify the host name (or IP address) of computer to ping
ping -i wait	ping -i 2	Wait time. The number of seconds to wait between each ping
ping -l preload	ping -l 4	Sends "preload" packets one after another.
Ping -n	ping -n	Numeric output, without host to symbolic name lookup.
Ping -p pattern	ping -p ff00	Ping Pattern. The example sends two bytes, one filled with ones, and one with zeros.
Ping -q	ping -q	Quiet output. Only summary lines at startup and completion
ping -r	ping -r	Direct Ping. Send to a host directly, without using routing tables. Returns an error if the host is not on a directly attached network.
Ping -R	Ping -R	Record Route. Turns on route recording for the Echo Request packets, and display the route buffer on returned packets (ignored by many routers).
ping -s PacketSize	ping -s 10	Sets the packet size in number of bytes, which will result in a total  packet size of PacketSize plus 8 extra bytes for the ICMP header
ping -v	ping -v	Verbose Output. Lists individual ICMP packets, as well     as Echo Responses
