[Libguestfs] hivexregedit doc - unix2dos command

On the page: http://libguestfs.org/hivexregedit.1.html#encoding Under "ENCODING" section is this command: unix2dos linux.reg | iconv -f utf-8 -t utf-16le > win.reg I couldn't get that to work without placing a redirection operator ('<') after "unix2dos". Could this be due to my version of unix2dos? Or just a typo. I'm a Linux n00b so my apologies for any "stupid" questions.
