In PowerShell it is not possible to redirect the output of an entire session (so Powershell.exe .... >filename.txt won't work) however a very similar text output can be produced using the Start-Transcript cmdlet.
The text files produced by PowerShell are by default in Unicode (UTF16), if you need a different encoding, use Out-File instead of the redirection operator.
PS C:\>Get-ChildItem c:\windows\system >> "c:\my logs\text1.txt"
PS C:\>Get-ChildItem c:\windows\system | Out-File text2.txt -encoding ASCII
PS C:\>Start-Transcript -path c:\docs\Text3.txt
