adb -d shell (or adb -e shell).

This command will help you in most of the cases, if you are too lazy to type the full ID.

From http://developer.android.com/tools/help/adb.html#commandsummary:

-d — Direct an adb command to the only attached USB device. Returns an error when more than one USB device is attached.

-e — Direct an adb command to the only running emulator. Returns an error when more than one emulator is running.

Another alternative would be to set environment variable ANDROID_SERIAL to the relevant serial, here assuming you are using Windows:

set ANDROID_SERIAL=7f1c864e
echo %ANDROID_SERIAL%
"7f1c864e"

Then you can use adb.exe shell without any issues.

I found this question after seeing the ‘more than one device’ error, with 2 offline phones showing:

C:Program Files (x86)Androidandroid-sdkandroid-tools>adb devices
List of devices attached
SH436WM01785    offline
SH436WM01785    offline
SH436WM01785    sideload

If you only have one device connected, run the following commands to get rid of the offline connections:

adb kill-server
adb devices

This gist will do most of the work for you showing a menu when there are multiple devices connected:

$ adb $(android-select-device) shell
1) 02783201431feeee device 3) emulator-5554
2) 3832380FA5F30000 device 4) emulator-5556
Select the device to use, <Q> to quit:

To avoid typing you can just create an alias that included the device selection as explained here.

There are two Broad use cases:

1) 2 hardware are connected, first is emulator and other is a Device.
Solution : adb -e shell....whatever-command for emulator and adb -d shell....whatever-command for device.

2) n number of devices are connected (all emulators or Phones/Tablets) via USB/ADB-WiFi:

Solution:
Step1) run adb devices THis will give you list of devices currently connected (via USB or ADBoverWiFI)
Step2) now run adb -s <device-id/IP-address> shell....whatever-command
no matter how many devices you have.

For Windows, here’s a quick 1 liner example of how to install a file..on multiple devices

FOR /F "skip=1"  %x IN ('adb devices') DO start adb -s %x install -r myandroidapp.apk

If you plan on including this in a batch file, replace %x with %%x, as below

FOR /F "skip=1"  %%x IN ('adb devices') DO start adb -s %%x install -r myandroidapp.apk

Create a Bash (tools.sh) to select a serial from devices (or emulator):

clear;
echo "====================================================================================================";
echo " ADB DEVICES";
echo "====================================================================================================";
echo "";

adb_devices=( $(adb devices | grep -v devices | grep device | cut -f 1)#$(adb devices | grep -v devices | grep device | cut -f 2) );

if [ $((${#adb_devices[@]})) -eq "1" ] && [ "${adb_devices[0]}" == "#" ]
then
    echo "No device found";
    echo ""; 
    echo "====================================================================================================";
    device=""
    // Call Main Menu function fxMenu;
else
    read -p "$(
        f=0
        for dev in "${adb_devices[@]}"; do
            nm="$(echo ${dev} | cut -f1 -d#)";
            tp="$(echo ${dev} | cut -f2 -d#)";
            echo " $((++f)). ${nm} [${tp}]";
        done

        echo "";
        echo " 0. Quit"
        echo "";

        echo "====================================================================================================";
        echo "";
        echo ' Please select a device: '
    )" selection

    error="You think it's over just because I am dead. It's not over. The games have just begun.";
    // Call Validation Numbers fxValidationNumberMenu ${#adb_devices[@]} ${selection} "${error}" 
    case "${selection}" in
        0)
            // Call Main Menu function fxMenu;
        *)  
            device="$(echo ${adb_devices[$((selection-1))]} | cut -f1 -d#)";
            // Call Main Menu function fxMenu;
    esac
fi

Then in another option can use adb -s (global option -s use device with given serial number that overrides $ANDROID_SERIAL):

adb -s ${device} <command>

I tested this code on MacOS terminal, but I think it can be used on windows across Git Bash Terminal.

Also remember configure environmental variables and Android SDK paths on .bash_profile file:

export ANDROID_HOME="/usr/local/opt/android-sdk/"
export PATH="$ANDROID_HOME/platform-tools:$PATH"
export PATH="$ANDROID_HOME/tools:$PATH"
