本文深入探讨了ADB exec-out命令的使用技巧，对比adb shell，该命令不使用pty，适用于处理二进制输出，如通过screencap捕获屏幕截图。同时，文章提供了在压缩目录时如何避免STDERR干扰的解决方案。

Unlike adb shell the adb exec-out command doesn't use pty which mangles the binary output. So you can do

Linux$ adb exec-out screencap -p > test.png (Note: Linux \n will be converted into \r\n on Windows)

Note that if you are using this technique for a command that produces output on STDERR, you should redirect it to /dev/null, otherwise adb will include STDERR in its STDOUT corrupting your output. For example, if you are trying to backup and compress a directory:

adb exec-out "tar -zcf - /system 2>/dev/null" > system.tar.gz
