shell script

1. When you need to jump to a certain path to perform operations, you can use the cd command. The following means to jump the current path to C:\ZhouXi

C:\shellShow>cd C:\ZhouXi          ---------//cd就是change directory的缩写
C:\ZhouXi>

2. When you need to debug your phone, but you are not sure whether the phone is connected, you can use adb devices to view the currently connected device

C:\ZhouXi>adb devices
List of devices attached
FRU6R20426000630        device    ---------//连接的平板
emulator-5554   device            ---------//android studio打开的虚拟机

3. The log needs to be viewed during apk debugging, you can use adb shell logcat to output the log

C:\ZhouXi>adb logcat -c                     -------//清除日志缓存，c代表clear
C:\ZhouXi>adb logcat >C:\ZhouXi\logcat.txt  ------//打印日志到C:\ZhouXi\logcat.txt，如果文件不存在则新建
^C                                    ------------------//日志打印需要使用ctrl+c来结束，否则一直输出日志
C:\ZhouXi>adb logcat -c | adb logcat >C:\ZhouXi\logcat.txt   ----//日志缓存清除和日志打印可以使用|合在一起
^C         -----//同上

4. When you need to install the apk on the computer to the phone, you can use adb install to install the apk

C:\ZhouXi>adb install app-debug.apk       ------//尝试安装app-debug.apk
Performing Streamed Install
adb: failed to install app-debug.apk: Failure [INSTALL_FAILED_TEST_ONLY: installPackageLI]  --//由于是测试apk，安装失败

C:\ZhouXi>adb install -t app-debug.apk    ------//加上-t表示允许test的apk安装
Performing Streamed Install
Success

5. When you want to transfer files to your phone, or pull files from your phone to your computer, you can use adb push and adb pull

C:\ZhouXi>adb push app-debug.apk /data/          ------//两者都需要手机root权限
C:\ZhouXi>adb pull /data/app-debug.apk

echo var: %var%           //打印var,通过%var%获取var的值
pause>nul                 //关闭显示“请按继续键继续...”

cmd显示结果:
var: xizhou
