android - 如何从当前时间戳获取 shell 输出。 Linux、Unix

Question

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 获得的程序输出，

它是一个连续的流，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？

Answer 1

根据 adb手册，可以分两步完成:

1. 使用 logcat -c 清除日志
2. 使用常规 logcat 调用进行连续日志监控

如果这应该结合在一起，我想只需运行 logcat -c && logcat 即可解决。
