Same, I was hoping for some mention of /proc/PID/fd*, but nothin'.

  /proc/ is not a fundamental to understanding Unix or Unix pipes and is not present on many Unixes.

    You're right, but for what it's worth, the folks that I've taught the nuance of pipes seem to really only "get it" after pointing them to /proc/PID/fd* and having them cat in/out the files there. It directly leads into much deeper understandings of what "everything is a file" means.
