a quick way to add timestamp for coredns(only use linux cli)

[anonymity12]

i find that dnstap cannot support date, only show hours and minutes, so i find a easy(maybe simple&stupid way) to log coredns,

here is the solution:

/usr/bin/coredns -conf /etc/storage/csc/coredns/Corefile 2>&1 | stdbuf -oL awk '{ print strftime("[%Y-%m-%d %H:%M:%S]"), $0 }' | stdbuf -oL tee -a log7.log

result:
