Monitoring a file until a string is found

I am using tail -f to monitor a log file that is being actively written to. When a certain string is written to the log file, I want to quit the monitoring, and continue with the rest of my script. Currently I am using: tail -f logfile.log | grep -m 1 "Server Started" When the string is found, grep quits as expected, but I need to find a way to make the tail quit too so that the script can continu

サブシェルでtailをバックグラウンド実行すると、パイプラインは止まってもtailは宙ぶらりんで残ってしまう。それが嫌ならchannelみたいにfifoで待ち合わせすればよい
