Thanks! For me, it doesn't print 1), but 2) and 3) just works well.

➤ adb $(android-select-device.sh) shell dumpsys window | grep mCurrentFocus
  3) 23456789ABCDEF     device
2) xxxxxxxxxx   device
Select the device to use, <Q> to quit: 2
  mCurrentFocus=Window{xxxxxxxxxxxxxxxxxxxxxxxxxxx}

BTW, alias adbs="adb \$(/drives/d/tools/bin/not_exported/android-select-device.sh)" is cool.
