Taking logcat and kernel logs simultaneously
提问by manugupt1
I am trying to take logs (logcat and kmsg) via the following command
我正在尝试通过以下命令获取日志（logcat 和 kmsg）
"logcat -v time -f /dev/kmsg | cat /proc/"
“logcat -v 时间 -f /dev/kmsg | cat /proc/”
However I am not sure, where the log file is stored, and what will be its name. How do I identify it
但是我不确定日志文件的存储位置以及它的名称。我如何识别它

OK, here are the results of a quick Google search:
好的，以下是快速 Google 搜索的结果：
What I got from those links are:
我从这些链接中得到的是：
- The last part of your command should actually be
cat /proc/kmsg logcat -v time -f /dev/kmsgwrites logcat outputs to kernel message buffer
- 命令的最后一部分实际上应该是
cat /proc/kmsg logcat -v time -f /dev/kmsg将 logcat 输出写入内核消息缓冲区
So,
所以，
logcat -v time -f /dev/kmsg | cat /proc/kmsg
will output both logcat and kernel logs to stdout(whatever it is). Probably, you may write the output to a file as follows:
将 logcat 和内核日志输出到stdout（无论它是什么）。可能，您可以将输出写入文件，如下所示：
logcat -v time -f /dev/kmsg | cat /proc/kmsg > /sdcard/log.txt
The above worked from adb shellprompt on a rooted Android 4.4.2 device.
以上工作adb shell在有根的 Android 4.4.2 设备上从提示开始。
Hope this helps.
希望这可以帮助。

Just execute the following line and that would show the kernel messages on to the logcat
只需执行以下行，即可将内核消息显示到 logcat
$ adb shell
$亚行外壳
$ logwrapper cat /dev/kmsg &
$ logwrapper cat /dev/kmsg &
$ logcat
$ logcat

Using below commands: start cmd.exe /c "adb shell cat /dev/kmsg > kmsg.txt" start cmd.exe /c "adb logcat -v threadtime > logcat.txt"
使用以下命令： start cmd.exe /c "adb shell cat /dev/kmsg > kmsg.txt" start cmd.exe /c "adb logcat -v threadtime > logcat.txt"
