comment command lines

i want to comment out some command lines in a group of powershell scripts but the conversion is not happening, i’m sure it has to do with my handling of the # in $newfile3, here is my code

$Folder = ‘C:\PowerShell\PS_Star*.*’
$file3 = ‘Invoke-Item $global:OutputReportFile’
$newfile3 = ‘#Invoke-Item $global:OutputReportFile’

Get-ChildItem $Folder | Where {$_ -IS [IO.FileInfo]} |
% {

(Get-Content $.FullName) -replace $file3,$newfile3 | Set-Content $.FullName

Write-Host "Processed: " + $.FullName


any ideas?

You have placed the # between the single quotes. PowerShell takes everything between single quotes literrally.

that’s what i thought too but the code doesn’t perform the remove and replace

The use of the single quote marks in your replacement text looks correct to me. Your problem is elsewhere.

To start debugging, I would just process the first file found and break up the pipeline to see which step fails. NOTE: this scriptlet assumes PowerShell V3. (Replace "-File" with "| Where-Object {-not $
.PSIsContainter}" for V2)

Get-ChildItem $Folder -File | Select-Object -First 1 | Foreach-Object {
$NewContent = (Get-Content $.FullName) -replace $file3,$newfile3
$NewContent | Set-Content "$($
Write-Host "Processed: " + $

This will leave you with a variable ($NewContent) that you can examine, plus the original file and the new file with the extension changed to ".TST" that you can compare. I’d check to see if the -Replace is actually working against the whole file, or if you might need to run it against each line separately.
