Hi, I have a program that constantly displays values on the screen. The program 'ping' for example.
What I'd like to do is watch the output and as soon as i see some values, i would do something. For example, as suppose when pinging a host I would constantly get a reply. however, if I remove the network cable, of my pc, I would start seeing host unreachable or something. As soon as I see this message, I would like to do something. This is how I want to do this (executing the program once and watching the output). I could probably run ping every one second and check the output of each execution, however, that is not how I want to do it. The program I will be running has to be run only once, like for example the 'top' program. Any idea how to accomplish this?
