I believe you have confused between ping on windows
and ping on linux. Altough on both operating system
ping is used in, generally, the same purpose, but it
takes different parameters.
On windows :
===================================================
F:\Tools>ping /?
Usage: ping [-t] [-a] [-n count] [-l size] [-f] [-i
TTL] [-v TOS]
[-r count] [-s count] [[-j host-list] |
[-k host-list]]
[-w timeout] target_name
Options:
-t Ping the specified host until
stopped.
To see statistics and continue -
type Control-Break;
To stop - type Control-C.
-a Resolve addresses to hostnames.
-n count Number of echo requests to send.
-l size Send buffer size.
-f Set Don't Fragment flag in packet.
-i TTL Time To Live.
-v TOS Type Of Service.
-r count Record route for count hops.
-s count Timestamp for count hops.
-j host-list Loose source route along host-list.
-k host-list Strict source route along
host-list.
-w timeout Timeout in milliseconds to wait for
each reply.
F:\Tools>
=====================================================
On Linux :
=================================================
brad_brock@leonhart:~$ ping -h
Usage: ping [-LRUbdfnqrvVaA] [-c count] [-i interval]
[-w deadline]
[-p pattern] [-s packetsize] [-t ttl] [-I
interface or address]
[-M mtu discovery hint] [-S sndbuf]
[ -T timestamp option ] [ -Q tos ] [hop1
...] destination
=================================================
It is the output from Windows and Linux on ping.
Please remark on option -n on both output.
This is taken from manual ping on Linux about -n
option :
-n Numeric output only. No attempt will be
made to lookup symbolic
names for host addresses.
