Operation Manual
If you only need to check the functionality of the connection, you can limit the number
of the packets with the -c option. For example to limit ping to three packets, enter
ping -c 3 example.com.
Example 13.10:

ping -c 3 example.com

64 bytes from example.com (192.168.3.100): icmp_seq=2 ttl=49 time=184 ms
64 bytes from example.com (192.168.3.100): icmp_seq=3 ttl=49 time=183 ms

rtt min/avg/max/mdev = 183.417/185.447/188.259/2.052 ms
The default interval between two packets is one second. To change the interval, ping
provides the option -i. For example, to increase the ping interval to ten seconds, enter
ping -i 10 example.com.
In a system with multiple network devices, it is sometimes useful to send the ping
through a specic interface address. To do so, use the -I option with the name of the
selected device, for example, ping -I wlan1 example.com.
For more options and information about using ping, enter ping -h or see the ping
(8) man page.
TIP: Pinging IPv6 Addresses
For IPv6 addresses use the ping6 command. Note, to ping link-local addresses,
you must specify the interface with -I. The following command works, if the
address is reachable via eth1:
ping6 -I eth1 fe80::117:21ff:feda:a425
