How to empty (clear) the logcat buffer in Android

如何清空（清除）Android 中的 logcat 缓冲区？
I use adb logcat from command line and pipe the output to a file, since the DDMS has a very limited buffer. At the moment, when I restart my app (after fixing bugs etc) the logcat buffer has data from the previous launch as well. Even uninstalling the app does not clear the buffer. The only way I've found so far to clear the buffer, is reboot. This is effective, but would like to know if there's an easier way.
我从命令行使用 adb logcat 并将输出通过管道传输到文件，因为 DDMS 的缓冲区非常有限。目前，当我重新启动我的应用程序时（在修复错误等之后），logcat 缓冲区也包含上次启动的数据。即使卸载应用程序也不会清除缓冲区。到目前为止，我发现清除缓冲区的唯一方法是重新启动。这是有效的，但想知道是否有更简单的方法。

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 root
adb logcat -b all -c
or
或者
adb root
adb shell logcat -b all -c
Use the following commands to know the list of buffers that device supports

I give my solution for Mac:
我给出了我的 Mac 解决方案：
- With your device connected to the USB port, open a terminal and go to the adb folder.
- Write: ./adb devices
- The terminal will show something like this: List of devices attached 36ac5997 device
- Take note of the serial number (36ac5997)
- Write: ./adb -s 36ac5997 to connect to the device
- Write: ./adb logcat
- 将您的设备连接到 USB 端口，打开终端并转到 adb 文件夹。
- 写入：./adb devices
- 终端将显示如下内容：List of devices connected 36ac5997 device
- 记下序列号 (36ac5997)
- 写入：./adb -s 36ac5997 连接设备
- 写：./adb logcat
If at any time you want to clear the log, type ./adb logcat -c
如果您想随时清除日志，请键入 ./adb logcat -c
