Searching through passed Logfile with something like this:
cat /path/to/logfile | grep -iEw 'some-ip-address-here|correspondig-mac-adress-here'
This gives me all the passed log lines until now so I can see what has been. Now I also want to see what's going on so I need to exchange
tail -f giving me this:
tail -f /path/to/logfile | grep -iEw 'some-ip-address-here|correspondig-mac-adress-here'
