There is NO output file generated - sh runs the iptables commands immediately from the pipe. Should you need an output file, consider using the tee utility.

Hello,
Don't know, that command is not saving my ip to iptables. I do not see my ip when I type iptables-save

Kind regards

OK, do it in two steps: first run the awk to control what the result is and double check on errors. Then, save the results to a file and source/run the file in a shell with the -x option set.
