# ping -i 4 192.168.1.100
above command send ping packets after every 4 seconds.

# ping -i 0.1 192.168.1.100

this command send ping packets after every 0.1 seconds.

6.how to change the ping packet size which is bydefault 64bytes?


# ping -s 200 192.168.1.100


7.How to specify the timeout for ping?

# ping -w 7 192.168.1.100
