Do something every 10 seconds batch file.

Question

I have a batch file:

arp -s 192.168.1.254 xx-xx-xx-xx-xx-xx
ipconfig /flushdns

How can I do these two commands on Windows XP, every 10 seconds?

Answer 1

:top
arp -s 192.168.1.254 xx-xx-xx-xx-xx-xx
ipconfig /flushdns
sleep 10
goto top

Edit: As mentioned in the comments, SLEEP won't be available in a normal install. You'll need something like the Windows 2003 Resource Kit, or some other trick to simulate it (the ping trick Bruno mentions), and notes to do so can be found here.

Answer 2

Try this one:

:loop
arp -s 192.168.1.254 xx-xx-xx-xx-xx-xx
ipconfig /flushdns
ping localhost -n 11 > nul
goto loop

The ping command will execute for 10 seconds, and all the output will be redirected to the NUL device, meaning that you will see no output from the ping command. It works indeed as a "sleep" command would.

Answer 3

Install Cygwin which will make sleep and cron available to you (among other things).

Answer 4

You could set up a Windows service to run your batch file.

Answer 5

Cheat:

Use this command to pause the batch for 10 seconds

choice /n/t:c,<10>/c:cc

Now, place it in a never ending loop in the batch and voilà!

Answer 6

More precise solution ping unexistent host once and set timeout

ping 1.0.0.0 -n 1 -w 10000 >nul

But it generate parasite traffic
