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.

I downloaded the file and put it into app-debug dir. I changed alias from adb to android-select-device but when I try to execute any adb command this message appears: bash: android-select-device: command not found. What could it be?

If you execute /path/to/android-select-device.sh directly what's the result?

My fault. I put the path to android-select-device wrong. Thank you.
