This is unclear, what is "network status" for you? Do you have some kind of deamon that monitor the "state" of your servers? Or some kind of centralized logfile? Or do you mean configuration file, maybe?
Please provide more information:
-Tell us what you are trying to do exactly (installing an application? which one? what have you done so far?)
-Give us details about what you call "network status" (are you really talking about the state of the server? If so, what application are you using to monitor it? Can you give an example? Otherwise, is there another name to this?)

Whatever...
If you want to create a new (empty) file in a shell script, use "touch", like in :
This will create an empty mynewfile.txt file.
To make a loop from 1 to 15, you could use something like (where SOMETHING is a command) :
You can also use "echo" to echo text in a file, like in :

sir iam sorry

using shell script a html file to be created .where the mentioned server/s are on or offi want to dispaly thsi in web .Or can i do this with PHP script to display the server connection [on/off] status through web

Create a html file from a shell script would be easy, however, "how" do you want to display this on the web?
I mean, it would be easy to create an html file and to put it on your LOCAL apache webserver, but if the LOCAL server goes down, how do you expect to be able to see this file?

Or do you have some kind of centralized REMOTE webserver that could "display" these files? In that case, you would need to share (with NFS or Samba?) your apache webserver root directory and to mount it on all of the computer you want to "display status", to copy their file there.

About the script itself... calling "/sbin/ifconfig" from a shell script and greping the network card you want to monitor could do what you want. Or you could just call "ping -c 1 something.com" from a script and check the result?
