How to empty (clear) the logcat buffer in Android [duplicate]

Question

adb logcat -c

Logcat options are documented here: http://developer.android.com/tools/help/logcat.html

The following command will clear only non-rooted buffers (main, system ..etc).

adb logcat -c

If you want to clear all the buffers (like radio, kernel..etc), Please use the following commands

adb root
adb logcat -b all -c

or

adb root
adb shell logcat -b all -c 

Use the following commands to know the list of buffers that device supports

adb logcat -g
adb logcat -b all -g
adb shell logcat -b all -g

I give my solution for Mac:

1. With your device connected to the USB port, open a terminal and go to the adb folder.
2. Write: ./adb devices
3. The terminal will show something like this: List of devices attached 36ac5997 device
4. Take note of the serial number (36ac5997)
5. Write: ./adb -s 36ac5997 to connect to the device
6. Write: ./adb logcat

If at any time you want to clear the log, type ./adb logcat -c

For anyone coming to this question wondering how to do this in Eclipse, You can remove the displayed text from the logCat using the button provided (often has a red X on the icon)
