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

Reason: Add missing pipe symbol and Note.
Below code is not printing ip file

Could you please let me know if I could make it shorter or make system less busy?
Thanks in advance

Please use CODE tags when displaying sample input, output, and code segments; not QUOTE tags.

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.

Of course not. At least, not immediately. ip is not written to by the awk command. The awk prints to screen, the while loop reads from stdin --> you're supposed to enter the IPs found manually (which I doubt is what you really want).

Final working status:
As has been pointed out before, the three awks can be concentrated into one as done in the example before. Redirecting stdout into the file ip PLUS piping it into something (here: while loop) doesn't work - use either. (Ususally, redirection takes precedence)
A while loop checking a closed file is somewhat pointless - either it exists or it does not.
The ban.sh is unknown, and so is grep3.sh, so there is not a snowball's chance in hell for to judge

Wouldn't it make sense you depict the entire situation (file/directory structure, input samples, scripts used, final action/output desired) so you can get useful help?
Hello Don,
I mean that it's not creating a file named ip
Thanks for your time and suggestions
Kind regards
Boris
Ouch. Yes, the script I suggested:
was missing a pipe symbol (as pointed out by RudiC). I intended to write:
But, as I said before, I have no idea if this is what you want to do since you still have not specified what you are trying to do! And, we have no idea what ./ban.sh does, whether you want to run it each time an IP address is added to the file ip, or if you just want to run it once each time awk processes your apache2 log file.

Hi All,
I am new to unix.
In this forum some days back, I have read something like below:
1) Do not use perl if awk can do your work.
2) Do not use awk if sed can do your work.

I do not re-collect the whole thing. I think it is good to know the precedence of using these... (2 Replies)

Hello,
I have a logfile which is in this format:

Is there a way to read the logfile line by line every time I execute the code and put the two numbers in the line in two separate variables?
