作为多年Android习惯使用ADB命令，对于HarmonyOS HDC命令如何使用？两者之间区别及原子化服务开发过程中HDC命令与ADB命令使用技巧，请移步下文讲解。
一、HDC与ADB介绍
HDC介绍
HDC，即HarmonyOS Device Connector，是HarmonyOS为开发人员提供的用于调试的命令行工具，通过该工具可以在windows/linux/mac系统上与真实设备或者模拟器进行交互。
HDC通过HarmonyOS SDK获取，存放于sdk的toolchains目录下，使用时将sdk的toolchains目录添加到环境变量。

ADB介绍
ADB，即 Android Debug Bridge，是一种功能多样的命令行工具，可让您与设备进行通信。adb 命令可用于执行各种设备操作（例如安装和调试应用），并提供对 Unix shell（可用来在设备上运行各种命令）的访问权限。它是一种客户端-服务器程序，包括以下三个组件：
- 客户端：用于发送命令。客户端在开发机器上运行。您可以通过发出 adb 命令从命令行终端调用客户端。
- 守护程序 (adbd)：用于在设备上运行命令。守护程序在每个设备上作为后台进程运行。
- 服务器：用于管理客户端与守护程序之间的通信。服务器在开发机器上作为后台进程运行。
adb 包含在 Android SDK 平台工具软件包中。您可以使用 SDK 管理器下载此软件包，该管理器会将其安装在 android_sdk/platform-tools/ 下。或者，如果您需要独立的 Android SDK 平台工具软件包，也可以点击此处进行下载。

二、HDC与ADB常用命令对比
HDC | ADB | 说明 |
hdc -h | adb --help | 查看帮助 |
hdc -v | adb --version | 查看版本 |
hdc list targets | adb devices | 查看连接设备 |
hdc kill | adb kill-server | 结束服务 |
hdc kill -r | adb start-server | 启动服务 |
hdc app install [安装包路径] | adb install [安装包路径] | 安装应用 |
hdc app uninstall package | adb uninstall package | 卸载应用 |
hdc hilog | adb logcat | 抓取log |
hdc shell hilogcat >log.log | adb shell logcat >log.log | 抓取log并保存 |
hdc shell reboot | adb reboot | 重启设备 |
hdc shell bm get -u | adb shell bm get -u | 获取UUID |
hdc file recv REMOTE… LOCAL | adb pull REMOTE… LOCAL | 接收文件 |
hdc file send LOCAL… REMOTE | adb push LOCAL… REMOTE | 发送文件 |
hdc shell screencap filename | adb shell screencap filename | 截屏 |
hdc shell screenrecord filename | adb shell screenrecord filename | 录屏 |
三、日常开发常用命令
日常FA开发中以上命令的使用对于前端同学来说比较陌生，命令不容易记住。如：获取UUID，命令记不住需要往期的赋能资料，最终才能获取到UUID。针对命令记不住的问题可通过提供简单脚本的方式，提供给前端使用。
注意：HDC服务和ADB服务不能共存。在执行脚本时，如果获取的数据为空，则需要确认手机设备使用的是hdc命令还是ADB服务。
确认方式：通过hdc list targets命令获取设备列表，如果获取到设备列表则当前使用的为hdc服务，否则为adb服务。可通过adb kill-server结束adb服务，再通过usb连接设备，使用hdc list targets命令获取设备列表，如果获取到列表则表示当前服务使用的是hdc服务。如下图操作：（1）获取UUID
脚本：uid.bat 已放置于下方资源处，如有需要自行下载。
hdc shell bm get -u > uuid.log将该指令生成uuid.bat脚本，通过脚本获取设备UUID。
（2）获取hilog日志
脚本：hilog.bat 已放置于下方资源处，如有需要自行下载。
hdc hilog（3）抓取log并保存
脚本：hilogs.bat 已放置于下方资源处，如有需要自行下载。
hdc shell hilogcat >log.log总结
- HDC命令及ADB命令都可以通过脚本方式获取或查看对应数据。
- 前端同学可按需自己编写脚本获取自己所需数据。
