Editing an RDP session with Notepad and Powershell

Question

This worked for me:

ls "~\desktop\CMR Desktop.rdp" -recurse | %{ (gc $_ ) -replace "session bpp:i:32", "session bpp:i:24" | set-content $_.FullName -force }

Instead of the -replace switch, which one do I use to add or insert new lines to the config file?

Such as:

ls "~\desktop\CMR Desktop.rdp" -recurse | %{
     (gc $_ ) -insert "set audioqualitymode:1:2" |
     set-content $_.FullName -force
}

The -insert or -add doesn't work.

Answer 1

Recurse and looping is redundant as there are no sub folders under a file:

ls "~\desktop\CMR Desktop.rdp" | %{ "set audioqualitymode:1:2" | Out-File $_.FullName -append }

or even easier:

"set audioqualitymode:1:2" | Out-File (ls "~\desktop\CMR Desktop.rdp") -append

You need to use append. Set-Content or using Out-File without the append parameter will completely overwrite the file with JUST the text in the quotes.
