Only if both commands support objects. If one of them doesn't then PowerShell just deals with text. I've sent the output of PowerShell commands to perl scripts and GNU utils without any problems. It just worked. I'm still a powershell newbie, and this has made it easy for me to learn it while still using what I know.
