I can best explain via example. Let's say I want to iterate through a directory and do something to each file:

  ls C:\ | foreach{echo $_.Name}

That will print out the file name. The $_ variable represents each file object that ls returns. Let's say I want the file creation times instead:

  ls C:\ | foreach{echo $_.CreationTime}

Or just the day of the week the file was created:

  ls C:\ | foreach{echo $_.CreationTime.DayOfWeek}

It's incredibly powerful. And the default is always a text representation of the object anyway, so it seems like text is getting piped, just like Unix. If you do this:

  ls C:\ | foreach{echo $_}

You get a typical directory listing.
