I use this for my e-mail logs, but I’m sure it could be adapted: tail -n 1000 -f /var/log/mail-submission.log | grep smtp.*relay | awk ' /sent/ {print "\033[32m" $0 "\033[39m"} /bounced/ {print "\033[31m" $0 "\033[39m"} /deferred/ {print "\033[33m" $0 "\033[39m"} ---------------------------------------------------- The main thing for me is to find things that your network is doing that you weren't aware of.
