#
# File:      pingi

This is absolutely awesome, @brunobraga!

Can you please modify it to report packet loss percentage and count on every line?

Hello I bumped in this script on Stack Exchange, your code is exactly what I wanted but there is a small issue. If the hostname is not resolved "sleep" statement is never run and i this case there is a flood of "name resolution error". Please move the sleep command out of if statement but keep it in while loop. Thanks
