Replacing text in a text file with special characters

Question

Hi all,
in my test text file i found an interesting issue, where i can't replace text that looks something like this "New Text Document - Copy (2).txt"
(gc $logeps)|foreach{$_ -replace "$($file.name)",""}|Out-File $logeps
the context of my $($file.name) is "New Text Document - Copy (2).txt"
how can i escape the parentheses characters inside of a variable that i am passing?
thanks

That should work if you're running PowerShell 3.0 or later, but in older versions, you'd run into errors if you try to run .Replace on an array of strings.
While I prefer the string .Replace method in this instance, for future reference, if you want to escape a literal string so it can be used in a regular expression, call the [regex]::Escape method:
$pattern = [regex]::Escape($file.Name)
(gc $logeps) -replace $pattern | Out-File $logeps
