Powershell ver 4. Windows 7.
I wanted to replace ',' with new lines in a text file. I tried below script
(Get-Content C:\Test\test.txt).Replace(',','`n') | Set-Content C:\Test\testv2.txt
[IO.File]::ReadAllText(C:\Test\test.txt) -replace ',',"`r`n" | Out-File C:\Test\testv2.txt
P.S. Sorry that don't have time to explain it, now.
