Actually it is an interesting exercise. What I need this is for remotely configuring my WiFi access points that runs with hostapd. So hostapd has a configuration file called hostapd.conf.

what I want is to send only the modifications in the conf file over a perl socket. I am able to do that already. But now I need to process the downloaded file and merge into the existing conf file and then reboot the AP.

I am new to perl so i am stuck for the time being :)
