can display the Android device selection list and enter the shell script for the specified Android device console

If you have multiple Android devices (including Android emulators) connected to your PC, you will need to use the Adb-s DeviceID shell when you enter the console. More trouble, this article has written a shell script file (need to be used under Linux or OS X, Windows needs to be newly written with bat or cmd).
The basic idea is to use the ADB devices command to scan how many Android devices are connected to the PC, then intercept the device name from the return value and display a menu. Finally, the user can select the sequence number in front of the menu item to enter the specified Android device. No more input DeviceID.

The effect is as shown.

shell.sh

Source Common. SH find_devices if " $selected _device " ""  Then -S $selected _device Shell $1fi         

You need to put the common.sh and shell.sh files in the same directory and execute the shell.sh (you need to set their executable permissions using the chmod command)
