How can I erase the old data from logcat?
提问by aarona
When I execute the command
当我执行命令时
adb logcat
adb logcat
while running the android emulator, all of the old logs blow past and so I figure they are stored in a file somewhere. Is there a command I can run to clear the logs and start fresh? If not, is there some other way to do this?
在运行 android 模拟器时，所有旧日志都过去了，所以我认为它们存储在某个文件中。有没有我可以运行的命令来清除日志并重新开始？如果没有，有没有其他方法可以做到这一点？

Dup 如何清空（清除）Android 中的 logcat 缓冲区
The following command will clear only non-rooted buffers (main, system ..etc).
以下命令将仅清除非根缓冲区（主、系统 .. 等）。
adb logcat -c
If you want to clear all the buffers (like radio, kernel..etc), Please use the following commands
如果要清除所有缓冲区（如收音机、内核等），请使用以下命令
adb logcat -b all -c
or
或者
adb root
adb shell logcat -b all -c

For me, adb logcat -cwas not working and was giving following error :
对我来说，adb logcat -c无法正常工作并出现以下错误：
failed to clear the 'main' log
For this, I first did :
为此，我首先做了：
adb shell
Than I did :
比我做的：
logcat -c
then exit the shell. This way I was able to clear logcat when same was not getting cleared from adb logcat -c
然后退出外壳。这样我就可以在没有从 adb logcat -c 中清除 logcat 时清除 logcat
