Hello Boris,
I still don't quite think you get it. Without seeing an example of what is in your log file, I'm just guessing, but try this instead of what you have now:
The tail in your pipeline isn't doing anything but wasting system resources. I think the awk above does the same thing as the three awk commands in your pipeline. I don't have an inotifywait utility on my system, but it looks like it is waiting for file opened by the awk command to be closed. If that is what it is doing, it makes MUCH more sense to just wait for the awk command to complete instead of sticking more stuff in a pipeline that doesn't belong in a pipeline. Your awk command output is being redirected to a file, so there is nothing for your while loop to read so your while loop should not be in the pipeline.
If the intent is to call your script every time a line of data is written to the file ip by your awk script, that would be something more like:
Hope this helps,
Don

Hi All,
