adb devices

Main function: View the currently connected devices, and the Android devices or emulators connected to the computer will be displayed in a list.

Output format:[serialNumber][state]

If there is no emulator or device currently running, adb will return List of devices attached as empty

offline: indicates that the device is not connected to the computer or does not respond
device: the device has been connected to the computer. Note that this state does not mean that the Android device is available. When the Android device is in the startup phase, it will return this state if the connection is successful.

Filter logs with different priorities: adb logcat *:W (filter logs with a lower priority than W)
