How to make a Batch file/Script that will ping target PC if reply then execute command.

thanks for the effort.. tested it, it didnt work.  btw, it doesnt seem complete to me.... T_T

It work for me.

Can I see your lines ?

Well ...it's not using ping, but if you are running this with administrative access to the machines, you can check for the existence of a file to see if the computer is online...


:1
if EXIST \\192.168.1.155\c$\boo.ini GOTO :RUNCOMMAND
GOTO :1
:RUNCOMMAND
echo This is the command you want to run

sorry, spelling error... boot.ini


:1
if EXIST \\192.168.1.155\c$\boot.ini GOTO :RUNCOMMAND
GOTO :1
:RUNCOMMAND
echo This is the command you want to run

PING does not return an errorlevel you need to use something like this to check using FIND on the output:

@echo off
ping 128.127.1.1 -n 2 -w 200 | find "TTL" >NUL
if %errorlevel%==0 (echo Is repsponding) ELSE (echo is not responding)

Good plan to check a file exists too, but there may be quite a delay while it tries to check - on my machine it was maybe 20-25 secs.

The original intent was to loop until reachable. So both the ping and the file exists approach are suitable. The ping allows for a finer control, however. Based on Steve's code:

:loop
ping PCNAME || goto loop
rem put here what to do if pc is pingable
goto end



(  ||  = double pipe , means execute next command if previous did not complete successfully )

Hello dragon-it,

Check my screen copy, it's not a fake !

Regards.

Curious... On Windows 2000 Pro SP4, XP Sp3, Server 2003 SP1? it does NOT set the errorlevel (just tried it again:)  Cut out some of the crap but the result is the same.  Is this new behaviour on Win 7 or Vista - what are you using?

C:\Documents and Settings\stephen>ping 10.0.0.1 -n 1 -w 100
Pinging 10.0.0.1 with 32 bytes of data:
Request timed out.
echo %errorlevel%
0

ping 127.0.0.1 -n 1 -w 100
Pinging 127.0.0.1 with 32 bytes of data:
Reply from 127.0.0.1: bytes=32 time<10ms TTL=128

echo %errorlevel%
0

C:\Documents and Settings\stephen>ping 10.0.0.1 -n 1 -w 100  || echo OK
Pinging 10.0.0.1 with 32 bytes of data:

ping 127.0.0.1 -n 1 -w 100  || echo OK

Pinging 127.0.0.1 with 32 bytes of data:

Quick test:

W2k SP4 Server: no
XP SP3: yes
W2003 R2 SP2 Server: yes

Looks like the behavio(u)r changed with XP.

Strange, didn't seem to work with my XP... maybe an old build.  That's useful to know, just got to remember which I'm using it on!

Thank you all for your reply on this matter, All posts was very helpful and I tried to combine most of them to reach my goal. eq. leakim971 solution is almost perfect (and "yes" ping does return an errorlevel, so i didn't use the "find" command. I did replaced his >>log.txt to >nul instead since i feel its not that suitable to make a log file for a ping command which loops until it reaches a reply. Again thanks to everyone!
