What have you tried so far? Please show your code.

Looks like 2 possible solutions to me. Use regex with the -replace operator or iterate over the lines in a foreach loop. I’d probably recommend using regex with the -replace operator. Here’s some references to get you started.

Post back with some code or questions.

You can use a simple loop to compare the current line with the next line. Example:

$text = Get-Content .\text.txt$newText = for ($i = 0;$i -lt $text.Count;$i++) {

if ($text[$i] -ne $text[$i+1]) {

$text[$i]

}

}

Set-Content -Path E:\Temp\Files\newFile.txt -Value \$newText
