对我的测试有效的方法:

Ubuntu bash终端:

$ adb devices
List of devices attached 
646269f0    device
8a928c2 device
$ export ANDROID_SERIAL=646269f0
$ echo $ANDROID_SERIAL
646269f0
$ adb reboot bootloader

Windows命令提示符:

$ adb devices
List of devices attached 
646269f0    device
8a928c2 device
$ set ANDROID_SERIAL=646269f0
$ echo $ANDROID_SERIAL$
646269f0
$ adb reboot bootloader

这使您可以使用正常的命令和脚本，就好像只有ANDROID_SERIAL设备附加。

或者，您可以每次都提到设备序列号。

$ adb -s 646269f0 shell

当有多个设备连接时，这个要点将为你显示菜单做大部分工作:

$ 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:

为了避免输入，您可以创建一个别名，其中包括此处解释的设备选择。

创建一个Bash (tools.sh)从设备(或模拟器)中选择一个串行:

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

然后在另一个选项中可以使用adb -s(全局选项-s使用设备与给定的序列号，覆盖$ANDROID_SERIAL):

adb -s ${device} <command>

我在MacOS终端上测试了这段代码，但我认为它可以跨Git Bash终端在windows上使用。

还记得在.bash_profile文件中配置环境变量和Android SDK路径:

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

下面是我为自己编写的shell脚本:

#! /bin/sh

for device in `adb devices | awk '{print $1}'`; do
  if [ ! "$device" = "" ] && [ ! "$device" = "List" ]
  then
    echo " "
    echo "adb -s $device $@"
    echo "------------------------------------------------------"
    adb -s $device $@
  fi
done

对于Windows，这里有一个简单的例子，告诉你如何在多个设备上安装一个文件

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

如果您计划在批处理文件中包含此文件，请将%x替换为%%x，如下所示

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

在命令前使用-s选项指定设备，例如:

adb -s 7f1c864e shell

对于多个模拟器，使用进程的IP和端口作为id，例如:

adb -s 192.168.232.2:5555 <command>

参见如何获取Android模拟器的IP地址? 但如果只有一个模拟器，请尝试: Adb -e <命令>
