Stop buffering of adb shell output

问题

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?

回答1:

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 adb/daemon/shell_service.cpp

回答2:

I don't see this behavior using adb 1.0.41.

Only while using tr which I use to delete "\r". In this case I use:

adb command ... | stdbuf -o0 tr -d $'\r'
