Hello baris35,
My repeated attempts to explain how pipelines work have clearly failed. You are still stringing together things in a pipeline that are completely unrelated to each other.

You say you now have final working code. It contains what appears to be an infinite loop inside an infinite loop. It contains a ps, grep, awk, awk pipeline and an if statement in the outer loop that will never be executed because the inner loop will never terminate. It runs the command ./ban.sh inside the inner loop, but we have no idea what that does, nor why you would want to run it repeatedly. You have given us no indication of why you need an infinite loop waiting for a file to be opened and closed repeatedly then that file that will only be opened and closed once by the preceding code.

You say that the code I suggested doesn't print the list of IP addresses it found. This is true; it only writes them to a file (the file named ip) just like your earlier code did.

If you're only going to show us code that doesn't work and then complain that our suggestions to help you improve it don't work, there is nothing we can do. If you're willing to write a clear description of what your code is trying to do, explain what your current code is doing correctly, and explain what your current code is failing to do; then we might be able to help you correct your code so it will do what you want it to do.
