Operational mode

The ping command tests whether a network host is reachable.

The ping command uses the ECHO_REQUEST datagram (ping) of the ICMP protocol to get an ICMP ECHO_RESPONSE from a host or gateway. ECHO_REQUEST datagrams have an IP and an ICMP header, followed by a struct timeval data type and then an arbitrary number of pad bytes that are used to fill the packet.

When the ping command is interrupted by typing <Ctrl>+c, a brief statistical summary is displayed.

This example shows how to print only the ping summary page for www.google.com.
