| What are the immediate users of this command? Is something broken? Are | we in need of patching something? Does it solve some problem that "tail | -r" cannot solve? Aside from tail needing coypu's new -q option to suppress the file name noise, clearly not, as the proposed tac is (literallty) "tail -rq" But we have plenty of other cases where we use the cmd name to affect behaviour (cu/tip cc/cpp more/less ...) it is convenient to have a different name for a different operating mode of the command (and tail -r is really nothing like any other use of tail, it just doesn't really belong). More importanly, the name is just so "right". kre ps: the tac in gnu coreutils is by no means "original" - the tac command way predates GNU - I forget who created it initially, but the real original (non GPL'd) version could probably be found if there was a good reason for that.
