如何使用ping命令作为变量在批处理文件中用作中断条件？

Question

I want to create a batch file to first ping a share drive on start to see if it is ready to be mapped, then map when the ping is returned. As psuedo, something like this:

while true:
    ping ipaddr -t
    if (ping returned):
        break
map drive

I believe the syntax would be something like:

:checkping
ping ipaddr -t
if ping:
    goto mountZ
fi
goto checkping

:mountZ
net use Z:....

So how do I go about setting the ping in a usable variable to break the loop?

Answer 1

@echo off
:checkping
ping 8.8.8.8 > nul
IF ERRORLEVEL 1 echo Not Connected &  goto checkping
IF ERRORLEVEL 0 echo Connected     &  net use Z:....
pause 

Answer 2

:loop
    net use K: \\127.0.0.1\C$
If errorlevel 1 goto loop

Is one simple way of doing it.

Answer 3

You could use the below. If there is a TTL (Time To Live) then it will go to A, otherwise it will continue.

:checkping
ping -n 1 www.google.com | findstr TTL && goto a
goto checkping
Break

:a
REM Mapped Drive is connected
