Thanks! This is really great trick. I will obviously use less +F for tailing single file. Meanwhile, tail -f still useful for simple tailing to multiple machine, like function dogfight_tail { logfile=/var/log/nginx/access.log pids="" for box in 02 03; do ssh lb$box tail -f $logfile | grep " 500 " & # find error machines pids="$pids $!" done trap 'kill -9 $pids' SIGINT trap wait } dogfight_tail
