I created a .BAT file in Windows 7 that has the following line:
PING XXX.XXX.XXX.XXX -t
(XXX replaces the actual IP number). However, when I double click on this batch file, I can see the ping command repeatedly being executed in a loop. I even tried to rename the ping.BAT
to ping.CMD
but the result is the same.
I want to avoid writing ping command through the command prompt, which is why I created the batch file. I don't know why the ping command is being continuously called when the same statement is put in a batch file.

It is a bit unclear what is exactly the problem you face since you don't provide any output or screenshot of what you don't like, but I'll explain the two most likely problems I see:
Given your script is called
ping.bat
and looks like this:then the interpreter (
cmd.exe
) searches/probes the paths in the environment variable%PATH%
for something that looks likeping
... and it does that by appending each suffix from%PATHEXT%
which contains something like.COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH;.MSC
. so, calling justping
from theping.bat
leads to a search forping.com
ping.exe
ping.bat
and so on. The interpreter will find aping.bat
in the current working directory (yourping.bat
) and calls it.So, you will have a nice recursion here: ping.cmd executes the first line, searches for "ping", finds "ping.cmd", executes the first line, searches for "ping", finds "ping.cmd", executes the first line, searches for "ping", finds "ping.cmd" ...
The second problem you might have is this:
The interpreter of the batch file will usually repeat the commands you have written to the .bat/.cmd file. Thus something like this
ping www.superuser.com
will look like this:If you want to get rid of
C:\Users\XYZ\Desktop>ping www.superuser.com
in the output of the script then you have to either prepend each line with an@
(for example, '@ping www.superuser.com') in the script or place a@echo off
before the bunch of command lines you want to execute "quietly".TL;DR; Don't call your bat files the same as existing programs.
