When trying to output a text file to the screen using PowerShell and the following command:

$configText = get-content "C:\Helloworld.txt"
Write-Host "Helloworld:"
Write-Host $configText

The output was:

Helloworld:
Line 1 Line 2 Line 3

I.e. no carriage returns that were in the text file. To get the output to be as per the text file (with each line being on a separate line), you can amend your script to be the following:

$configText = get-content "C:\Helloworld.txt" | Out-String
Write-Host "Helloworld:"
Write-Host $configText

This then output the expected:

Helloworld:
Line 1
Line 2
Line 3

I believe this is because as default get-content actually returns an array of strings, and displays them all on the same line when you do a Write-Host (even if you specify $OFS = "'r'n") so you have to get the content as a single string.
