Stop buffering of adb shell output

Issue

I observed this new behavior in adb v1.0.39. The command:

adb shell getevent -l

gives the output below:

Observe that the last line is incomplete. This happens on many different devices. The same command is working without buffering in adb v1.0.32.

How do I stop adb shell output buffering in adb v1.0.39?

Solution

Use adb exec-out instead of adb shell command to force the new adb to use the raw mode and avoid stdout buffering.

For more info read comments in shell_service.cpp
