        "Pipe", "gozinta", "thru" and "pipesinta" refer to the use of
        "|" in {Unix} shells to create a {pipe}.
     
        Some keyboards show both a solid vertical bar (code 124) and a
        broken vertical bar (code 166).
     
        [Does anyone call either kind of vertical bar "{pling}"?
        Other codes?]
