Android Debug Bridge is a versatile command-line tool that lets you communicate with a device. It's included in the Android SDK Platform-Tools package. Must-have tool while developing android apps.
adb is great, it becomes a bit cumbersome when used with more than one android device (connected real phone/emulator to host). You have to specify a "target device", by providing it's unique device number.
adbs ease this pain by giving you a nice UI for selecting "target device". Can be used interchangeably with
adbcommands to multiple devices/emulators
$ npm install --global adbs # or $ yarn global add adbs
$ adbs [adbs options] [adb command] Options all Run commands on all devices dev Run commands on all physical devices emu Run commands on all running emulators help | -h Displays this screen version | -v Display current adbs version Examples $ adbs all shell netstat $ adbs emu install app.apk
