# ping a host with a total count of 15 packets overall.    
ping -c 15 www.example.com

# ping a host with a total count of 15 packets overall, one every .5 seconds (faster ping). 
ping -c 15 -i .5 www.example.com

# test if a packet size of 1500 bytes is supported (to check the MTU for example)
ping -s 1500 -c 10 -M do www.example.com

# CMD PING

ping -n -c1 -Mdo -s 1472 172.17.1.2

ping -i 60 -a www.google.com
# Give an audible sound as soon as the server comes live.

ping -c100 4.2.2.2 | sponge | pee head tail 
# The pee command can run head and tail on same input. sponge waits for all the data first.

# Assuming my network is 10.10.0.0/24, if i run a ping on the broadcast address like
ping -c 5 -b 10.10.0.255 | grep 'bytes from' | awk '{ print $4 }' | sort | uniq

# Also using the "ping the broadcast address" method pointed out by chburd, this pipe should do the trick for you:
ping -c 5 -b 10.11.255.255 | sed -n 's/.* \([0-9]\+\.[0-9]\+\.[0-9]\+\.[0-9]\+\).*/\1/p' | sort | uniq

# Generating list of IP addresses and ping
for ip in 192.168.1.{1..10}; do ping -c 1 -t 1 $ip > /dev/null && echo "${ip} is up"; done
	oder
for i in {1..254} ;do (ping 192.168.1.$i -c 1 -w 5  >/dev/null && echo "192.168.1.$i" &) ;done

# Ping mit echo
ping -c 1 -t 1 192.168.1.1 && echo "192.168.1.1 is up!"

# oder ping mit exit code der variablen $?
ping -c 1 -t 1 192.168.1.1;
if [ $? -eq 0 ]; then
    echo "192.168.1.1 is up";
else 
    echo "ip is down";
fi

# Hiding ping output
ping -c 1 -t 1 192.168.1.1 > /dev/null && echo "IP is up"
	IP is up

# Add timestamp to the output of ping
ping some_host | while read LINE; do echo $(date): $LINE; done
# Explanation: The while loop reads the output of ping line by line, and echoes it back with $(date) prepended.

mtr google.com
# Most of us are familiar with ping and traceroute. How about combining the functionality of both the command into one with mtr command.

mping(){ ping $@|awk -F[=\ ] '/time=/{t=$(NF-1);f=2000-14*log(t^18);c="play -q -n synth 1 pl "f"&";print $0;system(c)}';}
# mping yahoo\.com or mping any other number of IPs that have various ping times. Try mping 127.0.0.1 vs. mping your gateway IP.

arping 10.0.8.5
# Like ping, but it uses an ARP request to check, which gets around host firewalls blocking ICMP. Only works on same subnet
