在许多 shell 命令中，输出是连续的事件流，例如系统日志。我只需要查看现在或当前系统时间的输出。这是我从 adb logcat 得到的程序输出，

它是一个连续流，显示系统启动时的事件，但我只需要来自当前系统时间的日志。那么，我该如何实现呢？

根据adb手册，可以分两步执行此操作：

  1. 使用清除日志logcat -c
  2. 使用常规logcat调用进行持续日志监控

如果这应该结合在一起，我想只是运行logcat -c && logcat将是解决方案。

我的问题用 logcat -c 选项解决了。更通用的解决方案是使用 tail -f 命令行选项。虽然它不是超级准确但有效。
