Usage:

1. Make an alias for this script, e.g. adb2, or simply run the script whenever you would otherwise run adb.
2. Run a regular adb command on the script: ./adb.sh install -r my_app.apk
3. If you have multiple devices attached, the script will list them all and asks which one to run it on
4. Hit a number, the command will be executed on that device

Example:

./adb.sh install -r my_app.apk

Output:

Choose a device to execute this command on:
  adb install -r my_app.apk

  [1] Nexus 6P
  [2] Nexus 5
  [a] All
  [c] Cancel
