Powershell Read File, search $$I and Replace, write file?

cane someone Help me a bit.
I want to read a Text file, Search for $$I and replace it with the current Dir Name, Then write the file again.
Well something does not work 🙁

$content = [IO.File]::ReadAllText("CC.comp")
$content = $content -replace '$$I','Split-Path -Path (Get-Location) -Leaf'
Print $content
pause

>Solution :

-replace uses regex and $ is a special regex character which needs to be escaped with \ if you want to match it literally:

'$$I' -replace '$$I', 'test'    # Nothing is replaced
'$$I' -replace '\$\$I', 'test'  # Outputs 'test'

However, much easier is to use the .Replace method for literal replacement, no escaping is needed:

(Get-Content CC.comp -Raw).Replace('$$I', (Split-Path $pwd -Leaf)) |
    Set-Content CC.comp
