Pipe Command To PowerShell from Shell Script

I have some Windbg script where I can call out to a cmd shell via the .shell command. Now I want to execute some Windbg command and pipe the output to the shell script which should start powershell.exe to process the input data. So far I did fail.

In principle it should be possible to pass data from stdin to powershell pipes?

echo C: | powershell.exe -Command "| dir"

I do not want to create an extra powershell script because that would complicate the windbg script further and create external dependencies.

You can use the predefined $input variable to use the text you echo into powershell. In conjunction with the pipeline, this works perfectly:

echo C:\ | powershell.exe -command "$input | dir"

Edit: You also need to use echo C:\. I'm not sure of the reasoning, but simply writing Get-ChildItem 'C:' defaults to the current directory.
