-b n       amount of ping data to send, in bytes (default 56)

-B f       set exponential backoff factor to f

-c n       count of pings to send to each target (default 1)

-C n       same as -c, report results in verbose format

-e         show elapsed time on return packets

-f file    read list of targets from a file ( - means stdin) (only if no -g specified)

-g         generate target list (only if no -f specified)             (specify the start and end IP in the target list, or supply a IP netmask)             (ex. fping -g 192.168.1.0 192.168.1.255 or fping -g 192.168.1.0/24)

-i n       interval between sending ping packets (in millisec) (default 25)

-l         loop sending pings forever

-m         ping multiple interfaces on target host

-n         show targets by name (-d is equivalent)

-p n       interval between ping packets to one target (in millisec)             (in looping and counting modes, default 1000)

-q         quiet (don't show per-target/per-ping results)

-Q n       same as -q, but show summary every n seconds

-r n       number of retries (default 3)

-s         print final stats
