解析Windows批处理文件的输出以在下一个批处理文件命令中使用

Question

我正在做一些Windows批处理文件“编程”，以使用AWS CodeDeploy注册应用程序修订版。

到目前为止，这是我的批处理文件中的内容：

@echo off
aws --region us-east-1 --endpoint-url https://codedeploy.us-east-1.amazonaws.com deploy push --application-name MyApp1 --s3-location s3://s3-codeDevel-MyApp1.zip --source .\ --description "Application Revision Pushed from Tst"

当我运行命令时：

aws --region us-east-1 --endpoint-url https://codedeploy.us-east-1.amazonaws.com deploy push --application-name MyApp1 --s3-location s3://s3-codeDevel-MyApp1 --source .\ --description "Application Revision Pushed from Tst"

...就其本身而言，上述命令的输出将显示在命令提示符中：

To deploy with this revision, run:
aws deploy create-deployment --application-name MyApp1 --s3-location bucket=s3-codeDevel-MyApp1,key=MyApp1.zip,bundleType=zip,eTag=f4f28724b951fdeeee61d57c24ceba99 --deployment-group-name <deployment-group-name> --deployment-config-name <deployment-config-name> --description <description>

我想在批处理文件中运行另一个命令，因为“ eTag”的值发生了变化，因此该文件将解析并在下一个命令中使用上面的输出。

归根结底，这是我希望我的批处理文件如下所示：

@echo off
aws --region us-east-1 --endpoint-url https://codedeploy.us-east-1.amazonaws.com deploy push --application-name MyApp1 --s3-location s3://s3-codeDevel-MyApp1.zip --source .\ --description "Application Revision Pushed from Tst"
aws deploy create-deployment --application-name MyApp1 --s3-location bucket=s3-codeDevel-MyApp1,key=MyApp1.zip,bundleType=zip,eTag=<Parsed from previous command> --deployment-group-name DeploymentGroup --deployment-config-name DeploymentConfigName --description "My Description"

我将如何完成这项工作？

多种技巧的组合：
-运行命令并从输出中捕获最后一行
-删除所有直到eTag
-从“ rest”中获取第一个单词-使用该值执行命令

@echo off
set "command=aws --region us-east-1 --endpoint-url https://codedeploy.us-east-1.amazonaws.com deploy push --application-name MyApp1 --s3-location s3://s3-codeDevel-MyApp1 --source .\ --description "Application Revision Pushed from Tst""
for /f "delims=" %%a in ('%command%') do set "line=%%a"
set "line=%line:*eTag=%"
for /f "delims== " %%a in ("%line%") do set "key=%%a"
echo Debug: Key=%key%
aws deploy create-deployment --application-name MyApp1 --s3-location bucket=s3-codeDevel-MyApp1,key=MyApp1.zip,bundleType=zip,eTag=%key% --deployment-group-name DeploymentGroup --deployment-config-name DeploymentConfigName --description "My Description"
