Long output format showing additional device information (product, model, device, transport_id)

[serial] [state]

$ [serial] [state] product:[name] model:[name] device:[name] transport_id:[id]

sudo dnf install android-tools

sudo pacman -S android-tools

sudo apk add android-tools-adb

sudo zypper install android-tools

nix profile install nixpkgs#android-tools

CAVEATS

Devices showing "unauthorized" require you to accept the RSA key prompt on the device. "No permissions" errors on Linux usually require udev rules for your device. Emulators appear as emulator-5554 or similar.

HISTORY

The adb devices command has been part of adb since its initial release with the Android SDK in 2008. The -l flag for extended information was added later to help distinguish between multiple devices of the same model.
