Powershell 无法访问运行时环境变量

Question

I want to create a task which calls a Powershell script to do some processing. However I can't access Azure Batch runtime environment variables from my Powershell script.

I can access via cmd, command below correctly outputs

D:\batch\tasks\applications\test12020-05-04-17-32':

cmd /c echo %AZ_BATCH_APP_PACKAGE_Test#1%

However equivalent Powershell command below shows incorrect output

%AZ_BATCH_APP_PACKAGE_Test#1%':

powershell -Command echo %AZ_BATCH_APP_PACKAGE_Test#1%

Of course there is a hacky way around this which is to create a.bat script to call my.ps1 script. But I was looking for a better solution.

Is it possible to access Azure Batch runtime environment variables from Powershell?

Answer 1

As iRon said, echo is not really a PowerShell command, try the code as below:

powershell -Command $Env:ComSpec

The environment variables in my local is as below:

And here is the PowerShell running snapshot:
