batch file

Hi i am looking for a batch file which can check my site if all verticals are reponding well or not. i am new to batch programming, hence i need your help,,,

i am looking for a batch programme which will do the following for me….

ping google.com -t >> c:\test.txt

now there is a average value of ping response in test.txt

check in the average > 0 , or check if loss is not 100% then
print google.co is reponding well.
else
there is some issue and google is not responding well….. . . . .

all we have to do is get the input from one file and check it if it is what we want or something else….

If got an idea… please post…………

Thanx in advace…. MD
