dup vs tee

the name "dup" may be confusing, shouldn't it rather be "tee" ?

It is named dup because it is clear that it duplicates a stream, and also not to confuse it with "tee". "tee" does not offer the same features and should not be used with vpp.

I do not mean to use the program "tee", my concern is with the choice of the name "dup" for this function (creating a new stream with the same contents). This has always been called "tee", whereas dup(2) is used to give a new name to the same stream (without creating a new stream).
