Power of PING

In our respective interactions with various networks accessible to administrators we keep pinging so many IPs for testing the connectivity at various times like ping 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

ping -c countping -c 10Specify the number of echo requests to send.
Ping -dping -dSet the SO_DEBUG option.
Ping -fping -fFlood ping. Sends another echo request immediately
after receiving a reply to the last one.
Only the super-user can use this option.
Ping hostping the host name (or IP address) of computer
to ping
ping -i waitping -i 2Wait time. The number of seconds to wait between
each ping
ping -l preloadping -l 4Sends "preload" packets one after another.
Ping -nping -nNumeric output, without host to symbolic name lookup.
Ping -p patternping -p ff00Ping Pattern. The example sends two bytes, one
filled with ones, and one with zeros.
Ping -qping -qQuiet output. Only summary lines at startup and
ping -rping -rDirect Ping. Send to a host directly, without using
routing tables. Returns an error if the host is not on
a directly attached network.

Echo Request
packets, and display the route
buffer on returned packets (ignored by many
ping -s PacketSizeping -s 10Sets the packet size in number of bytes, which will
