[Help] Hide flood ping process in terminal

Hi
I have wrote a script to check latency of pppoe-clients to pppoe-server. script runs flood ping more than 100 times and result of script will be writen on terminal. The problem is result of flood ping will be writen in the terminal too and fill the terminal screen. Finding script result between flood ping status is so annoying.
Is there any way to run flood ping in background of terminal or stop flood ping to write result on terminal?

Any idea?
