====== ping ======

Normal ping operation is continuous.
<code>
ping 8.8.8.8
</code>

To get intermittent statistics, the SIGQUIT signal can be sent to the ping command.

Example output:
<code>
64 bytes from 8.8.8.8: icmp_seq=185 ttl=116 time=20.8 ms
64 bytes from 8.8.8.8: icmp_seq=186 ttl=116 time=22.1 ms
186/186 packets, 0% loss, min/avg/ewma/max = 20.775/24.063/23.094/37.955 ms
64 bytes from 8.8.8.8: icmp_seq=187 ttl=116 time=21.3 ms
64 bytes from 8.8.8.8: icmp_seq=188 ttl=116 time=22.7 ms
64 bytes from 8.8.8.8: icmp_seq=189 ttl=116 time=28.3 ms
</code>

Key combination while running:
''CTRL''+''\'' or ''CTRL''+''|'' or ''CTRL''+''4'';

Send to one or more known pids
<code>
kill -SIGQUIT <pid> [...]
</code>

Send to all running
<code>
ps -o pid= -C ping | xargs -r kill -SIGQUIT
</code>

Periodically send to all running
<code>
while sleep 20; do ps -o pid= -C ping | xargs -r kill -SIGQUIT; done
</code>

As a background job
<code>
while sleep 20; do ps -o pid= -C ping | xargs -r kill -SIGQUIT; done &
